Therefore, when using grounded thermocouples, do not ground control output terminals. (Doing so may result in temperature measurement errors due to unwanted current paths.) • There is basic insulation between the power supply inputs and outputs for this product. If reinforced insulation is required, connect the input and output terminals to equipment without any exposed charge-carrying parts, or to equipment with basic insulation sufficient for the maximum operating voltage of the power supply and the inputs and outputs. • To comply with the standards for noise terminal voltage for class A in EN 61326, install a noise filter (Densei Lamda MXB-1206-33 or the equivalent) to the DC power line as close as possible to the Temperature Controller. Using with the E5ZN-SCT24S-500 Wiring for terminals 1 to 18 is the same as for the E5ZN-SCT18-500.

Ensure that the rated voltage is reached within 2 seconds of turning power ON. 10.Allow 30 seconds’ warm-up time. 11.Install the product as far away as possible from devices that generate strong, high-frequency noise and devices that generate surges. 12.Keep wiring separate from high-voltage power lines or power lines carrying large currents. Do not wire in parallel with or together with power lines. • Locations subject to exposure to water or oil • Locations subject to intense temperature changes 15.When the Terminal Unit is separated from the Temperature Controller, under no circumstances touch the electrical components or apply shock to the Temperature Controller. 16.Do not use solvents to clean the product. Use commercial alcohol. 17.After wiring is completed remove the dust-protection label to allow proper heat dissipation. 18.When mounting the Temperature Controller to the Terminal Unit, make sure that the hook on the side of the Temperature Controller facing the Terminal Unit is inserted properly. 19.Install the DIN track vertically. 11 E5ZN ■ Precautions for Correct Use Service Life Use within the following temperature and humidity ranges: • Temperature: −10 to 55°C (with no icing or condensation) • Humidity: 25% to 85% If the product is installed inside a control panel, the temperature around the product (and not the temperature around the control panel) must be kept below 55°C. With electronic devices like the E5ZN, the service life will depend not only on the number of switching operations performed by the relay but also on the service life of the internal electronic components. The service life of these components depends on the ambient temperature; it will be shorter if the ambient temperature is high, and longer if the ambient temperature is low. For this reason, the service life of the product can be lengthened by keeping the inside of the E5ZN at a low temperature. Operating Precautions 1. A time of approximately 4 s is required after the power supply is turned ON until the outputs turn ON. Take this time into consideration when the Temperature Controller is incorporated in a sequence circuit. 2. Using the product near radios, televisions, or other wireless devices may result in reception interference. Mounting and Dismounting • To mount using a mounting track, first hook part A (see below) onto the track and then push down on part B. If several Units are mounted side-by-side or are arranged vertically, the heat generated may cause the internal temperature of the Units to rise, reducing service life. To prevent this, take steps to ensure that the Units are cooled, such as installing fans. Ensure, however, that the terminals are not also cooled, otherwise correct temperature measurement will not be possible. Measurement Accuracy • To dismount, insert a flat-bladed screwdriver into part C, pull the hook down, and then lift the bottom part of the E5ZN upwards. When extending the lead wires for thermocouples, use a compensating conductor appropriate for the type of thermocouple used. When extending the lead wires for platinum resistance thermometers, use lead wires with a low resistance, and make the resistance in the 3 lead wires equal. Make sure that the temperature sensor type and the input type of the E5ZN are the same. Mount the E5ZN horizontally. If significant errors occur, check that input compensation has been set correctly. Waterproofing 30 mm min. The degree of protection is given below. Parts for which the degree of protection is not clearly indicated, and parts with [email protected] ratings (where @ is not 0) do not have waterproof specifications. • Temperature Controller: IP00 • Terminal Unit: IP00 Stopper • Mount the E5ZN at least 30 mm away from other devices to ensure easy mounting and dismounting.
