Please review these important safety warnings. WARNING DANGER – HIGH CURRENT HAZARD! Power terminals pose an extreme arcing hazard when module is charged. Always discharge module prior to removal or handling. For information about the discharge procedure, refer to Section 7. Do not operate unit above specified voltage: INPUT Across Battery Positive (B+) and Battery Negative (B-): 32V max OUTPUT Across Starter (S+) and Battery Negative (B-): Do not connect to other voltage sources. Do not operate unit above specified temperature rating of +149⁰F (+65⁰C). Protect terminals from accidental shorting. If jump start is required use the external jump post if the vehicle is equipped with one, or jump across any Battery Positive (+) and Battery Negative (-) Terminal. WARNING DO NOT CONNECT IN REVERSE POLARITY! Do not connect the terminals in reverse (+ to – and/or – to +). Sparks and arcing will occur on a charged ESM creating a shock and/or burn hazard. Permanent damage to the ESM will also occur. WARNING DANGER DO NOT CONNECT CABLES FROM THE BATTERY TO THE STARTER (S+) TERMINAL OF THE ESM. This will short the batteries and cause arcing. WARNING WARNING – THIS IS NOT A BATTERY! DO NOT JUMP START Do not connect battery or Jump Start across the STARTER (S+) and BATTERY (B-) terminals. Chance of arcing or damage to the battery. Installation Guide and User Manual – 24V Engine Start Module (ESM) Document No. 3000313.7 © 2012, 2013, 2014, 2015 Maxwell Technologies, Inc. Page 1 2 Introduction The Engine Start Module by Maxwell Technologies, Inc. is intended to provide years of reliable starting for high compression gas or diesel engines up to 15L in displacement. The 24V ESM works with either 12V or 24V vehicle electrical systems and connects directly to a 24V starter solenoid. It is designed to recharge from an existing system battery(s) and provides starting power across a broad temperature range even when batteries would not have sufficient power. There are two products in the 24V ESM family, the ESM ULTRA 31/900/24V, and the ESM ULTRA 31/1100/24V. Please make sure you install the correct ESM product for the engine displacement size shown in the specification table in Section 11. 3 Unpacking Inspect the shipping box for signs of damage prior to unpacking the ESM. Damage to the shipping box or ESM should be reported to the carrier immediately. Retain the shipping materials until the unit has been inspected and is determined to be operational. Remove the ESM from the shipping box by lifting the ESM straight up. The ESM weighs only 19.2 lbs. (ESM ULTRA 31/900/24V) or 19.6 lbs. (ESM ULTRA 31/1100/24V) and is significantly lighter than a similarly sized lead-acid/AGM battery. DO NOT lift the ESM from the box or carry it using the provided jumper wire from the Starter (+) to the Battery (–) terminals. Discard jumper wire before installation. If the unit is found to be defective or any parts are missing, contact your original Point of Purchase or Maxwell Technologies, Inc. Technical Support toll-free at (888) 890-3337. A Return Material Authorization (RMA) number must be issued prior to returning the unit for repair or replacement. 4 Aftermarket Accessories Required for Installation Additional materials that may be needed for installation (see step 7 in Section 5.2.2, below) are shown below. These items are not included with ESM, but may be necessary to isolate other vehicle electronic nonstarting loads from the starter system. These are not required for new trucks with the ESM factory installed from the Original Equipment Manufacturer (OEM). Terminal block, Stainless Steel 3/8”–16 thread or equivalent. Examples are shown below: In place of a terminal block, a simple Stainless Steel 3/8” bolt, washer and nut may be used to connect non-starter vehicle loads to the batteries. Electrical insulation material (Heat Shrink) is also required for proper isolation. 0 AWG – 6 AWG (or appropriately size cable for the load) Cable with 3/8” ring lugs to connect other vehicle electronic non-starting loads to a Positive (+) battery terminal. Tools Required: (not supplied) • Large Compound-Action Crimp Tool (or similar) • Standard Shop Tools Installation Guide and User Manual – 24V Engine Start Module (ESM) Document No.: 3000313.7 © 2012, 2013, 2014, 2015 Maxwell Technologies, Inc. Page 2 5 Installation 5.1 Mounting Location The 24V ESM is designed to mount in the same space as a BCI Group 31 battery. The typical location is in the battery box of a Class 3-8 truck. If there is adequate space, the ESM should be installed in addition to batteries. If batteries fill the battery box, one battery must be removed (12V systems only) and replaced with the ESM. In 24V systems there is generally no available space to accommodate an extra battery so it may be necessary to fabricate a bracket or shelf along with a hold-down for the ESM in a safe location. However, a 24V ESM can replace one of the 12V batteries for use with a 24V starter motor on a 12V vehicle configuration. An installation video is available at the Maxwell Technologies, Inc. Website for additional installation instructions. Please visit http://www.maxwell.com/esm/video and click on the Maxwell Technologies ESM Installation Video. On some vehicles the Diesel Particulate Filter (DPF) After-Treatment System (ATS) may be located near the vehicle battery box. These systems typically generate very high temperatures during the regeneration process which may cause the Engine Start Module to experience an Over-Temperature Fault (>149⁰ F / 65⁰ C). Mount the ESM far away from the DPF. Refer to Section 6, below for additional diagnostic and troubleshooting information. 5.2 Electrical Installation WARNING DANGER DO NOT CONNECT BATTERY CABLES TO THE STARTER+ TERMINAL OF THE ESM. This will short the battery and cause arcing. 5.2.1 Electrical Connection Identification Push-to-Test Button (Activates Status LEDs) Battery (–) Terminal Ground Connection Battery (+) Terminal +12V or +24V Input Starter (+) Terminal Status LEDs ULTRA 31/1100/24V shown for illustration purposes Installation Guide and User Manual – 24V Engine Start Module (ESM) Document No.: 3000313.7 © 2012, 2013, 2014, 2015 Maxwell Technologies, Inc. Page 3 5.2.2 Cable Selection Installation of the ESM requires adding new cables from the ESM Starter (+) terminal to the Starter Solenoid positive terminal and the ESM Battery (-) terminal to the Starter Solenoid negative terminal. Typically a smaller diameter wire gauge cable is recommended to meet starter motor life requirements due to the higher current supplied by the ESM. All cabling used to replace the starter cables should have insulation that meets the requirements as per SAE J1127, SAE J2549 and TMC RP 166. Cable insulation recommendations are: a. 125°C Rated Cross-linked polyethylene — SAE J1127 Type SGX. b. 125°C Rated Thermoset Elastomer — SAE J1127 Type SGR where flexibility is required. Selection of the correct size American Wire Gauge (AWG) of cable depends upon the length of the Positive and Negative cables required to connect the ESM to the Starter. Add both the Positive and Negative cable lengths from the ESM to the Starter for total length and select the cable size from the table below: RECOMMENDED ESM TO STARTER SOLENOID POSITIVE AND NEGATIVE CABLE SIZE SELECTION TABLE Total Cable Length Feet 15 - 20 Feet 20 - 25 Feet 25 - 30 Feet 30 - 40 Feet (Length in Meters) (4.5 - 6.1 m) (6.1 - 7.6 m) (7.6 - 9.1 m) (9.1 - 12.2 m) Use AWG Cable Size 2 AWG 1 AWG 1/0 AWG 2/0 AWG 2 2 2 2 (Metric Cable Size) (35 mm ) (50 mm ) (50 mm ) (70 mm ) Select the proper gauge cable for the total length of the positive and negative cables from the ESM to the Starter Motor. Note: Cable gauges in the table above may seem small. They are correct and must be followed to achieve the maximum life of the starter motor. 5.2.3 Pre-Installation Checks 1. Prior to installing the ESM test the starting and charging system to isolate any pre-existing problems. Refer to the Technology and Maintenance Council (TMC) of the American Trucking Associations (ATA) Recommended Practice 129A (RP 129A) for procedures to test the cable interconnects between all the starting and charging system components for maximum voltage drop. Repair any issues found before proceeding. 2. Remove all cables from the vehicle batteries, noting where they were originally connected. 3. All cable lug terminations and battery terminals should be thoroughly cleaned to remove grease and oxidation. 4. Test the vehicle batteries individually and ensure they are properly charged to avoid issues later. Remove and replace any batteries that are discharged below their specified voltage or failed to test to their Cold Crank Amp (CCA) rating. 5. Place the ESM in the desired location being careful to align the (+) and (-) terminals in line with the existing Vehicle Battery(s) (+) and (-) terminals; remove a Battery if needed to install the ESM. DO NOT CONNECT THE ESM UNTIL INSTRUCTED. 5.2.4 Wiring Instructions (refer to the “before and after” installation diagrams below) 1. For aftermarket installations remove all the cables from the Starter Solenoid Positive terminal. Note: If the Starter includes an Integrated Magnetic Switch the short cable from the Magnetic Switch to the Starter Solenoid Positive Terminal can remain connected. All other connections to Starter Solenoid Positive Terminal must be isolated from the ESM. 2. Most vehicle manufacturers connect the Alternator and other vehicle power cables to the Starter Solenoid Positive Terminal. Remove the Alternator, any vehicle power cables and Battery (+) cables from the Starter Solenoid Positive Terminal. Connect these together using a terminal block or a nut and bolt so that they are isolated from the Starter Solenoid Positive Terminal but remain connected to any Battery (+) terminal or most positive Battery (+) terminal in a 24V system. Installation Guide and User Manual – 24V Engine Start Module (ESM) Document No.: 3000313.7 © 2012, 2013, 2014, 2015 Maxwell Technologies, Inc. Page 4 3. Mount the Terminal Block or other junction point to a secure location and make sure it is properly isolated from all vehicle grounds. Securely insulate, tie wrap and/or bundle all loose cables to minimize damage from vibration, potential grounds, abrasion and corrosion. 4. Remove the Alternator cable connection and other vehicle ground cables from the Starter Negative Terminal. Connect these together using a terminal block or a nut and bolt so that they are isolated from the Starter Negative Terminal but remain connected to any Battery (-) terminal or most negative Battery (-) terminal in a 24V system. If there is another cable from the Starter Negative Terminal to the frame remove and discard that cable. 5. Mount the Terminal Block or other junction point to a secure location and make sure it is properly isolated from all vehicle grounds. Securely insulate, tie wrap and/or bundle all loose cables to minimize damage from vibration, potential grounds, abrasion and corrosion. Note: At this point in the installation the Starter Motor Positive and Negative Terminals should now be completely isolated from the Battery Positive and Negative Terminals. All connections that were previously connected to the Starter Positive and Negative Terminals should be connected to Battery (+) and Battery (-), respectively. 6. Construct two new cables, one positive and one negative to connect the ESM to the Starter Solenoid. The recommended cable size (AWG) can be found in the table above based upon the length of the total cable, positive and negative circuit. a. The Positive (Red) cable from the ESM Starter (+) terminal should have a 3/8” lug to connect to the ESM Starter (+) terminal, and a ½” lug to connect to the Starter Solenoid Positive terminal. b. The Negative (Black) cable from the ESM Battery (-) terminal should have a 3/8” lug to connect to the ESM Battery (-) terminal, and a ½” lug to connect to the Starter Solenoid Negative terminal. c. Wrap both cables with a High Temperature Corrugated Wire Loom to prevent abrasion or heat-related damage. d. When routing cables avoid placement near sharp frame edges and secure the cables to existing cables with tie wraps every 18 inches. 7. At the batteries, connect the cable from the primary 12V or 24V Battery Negative (-) Terminal to the “BATTERY –” terminal of the ESM. 8. Connect the cable from the primary 12V or 24V Battery Positive (+) Terminal to the “BATTERY (+)” terminal of the ESM. The ESM will now begin its initial charging once connected to the vehicle batteries. Reconnect all previous cables removed from the vehicle batteries. 9. Connect the new Starter Solenoid Negative Terminal cable to the “BATTERY (-)” terminal of the ESM. 10. Before connecting the cable from the Starter Solenoid Positive Terminal to the Starter (+) Terminal of the ESM measure the voltage from the cable lug to both Battery Positive (+) and Battery Negative (-) Terminals. The voltage should read 0 volts for both. A voltage reading on either test indicates the Starter Solenoid may be bad or there is another wiring path from the Starter Solenoid to the batteries. This will result in improper ESM operation and must be corrected before continuing with the installation. See figure below.

Page 10 7 ESM Discharge Prior to storing or packing the ESM for return on an authorized RMA please discharge the ESM as follows: 1) If the ESM Starter+ terminal to Battery- terminal voltage is above 2V: a. Disconnect all cables from the ESM. b. Connect a 24V load, such as a headlight (or two 12V headlights connected in series) or a 24V blower motor, across the “STARTER +” and “BATTERY -” terminals. Leave connected until the light goes out or the blower motor stops running. This will discharge the voltage stored in the ESM. c. Verify voltage is 2V or less. d. DO NOT use a cable, bare wire or low/no resistance conductor to discharge the ESM! 2) Using a voltmeter, measure the voltage between the “STARTER +” and “BATTERY -” terminals. If the voltage is under 2V, the ESM is now considered safe for handling and shipping. 8 Maintenance Terminals should be periodically checked for oxidation or loose connections and cleaned or tightened as necessary. Prior to removal or system maintenance, ensure that the module is discharged (See section 7). No other regular maintenance is required. 9 Storage The module can be stored fully discharged in the original package in a dry place for up to four years. Observe the maximum storage temperature as stated in the product specifications below. Discharge the ESM prior to storing or shipment. 10 Disposal Do not incinerate or recycle with batteries.
