1305 Connection/Installation Guide Power Wiring Input and output power connections are performed through a ten position terminal block, TB1. (1) Connection for Dynamic Brake Resistors for all models except the 200-230 Volt, 0.37 to 75kW (1/2 to 1 HP) drive. NOTE: The[DB Enable] parameter must be enabled for proper operation. (2) For single phase applications, the AC input line can be connected to any two of the three input terminals R, S, T (L1, L2, L3). (3) Bulletin 1305 drives are UL listed and CSA certified as a motor overload protective device. An external overload relay is not required for single motor applications.

Belden 9460 (or equiv.) - 18 AWG (0.750 mm2), twisted pair, shielded. Note: This drive is not intended for use with single phase motors. Conduit If metal conduit is preferred for cable distribution, the following guidelines must be followed. 1. Drives are normally mounted in cabinets and ground connections are made at a common ground point in the cabinet. If the conduit is connected to the motor junction box and at the drive end, no further conduit connections are necessary. 2. No more than three sets of motor leads can be routed through a single conduit. This will minimize “cross talk” that could reduce the effectiveness of the noise reduction methods described. If more than three drive/motor connections per conduit are required, shielded cable as described above must be used. If practical, each conduit should contain only one set of motor leads. ATTENTION: To avoid a possible shock hazard caused by induced voltages, unused wires in the conduit must be grounded at both ends. For the same reason, if a drive sharing a conduit is being serviced or installed, all drives using this conduit should be disabled. This will eliminate the possible shock hazard from “cross coupled” drive motor leads. Motor Lead Lengths Installations with long cable lengths between the 1305 drive and motor may require the use of an output reactor or Terminator. The following guidelines allow for selection of the appropriate drive HP rating (and output reactor or Terminator, if required) to work with an existing motor, and provide motor–lead length solutions for new installations. Voltage doubling at motor terminals, known as reflected wave phenomenon, standing wave or transmission line effect, can occur when using long motor cables with drives. Long motor cables can cause capacitive charging current in excess of the rating of a smaller drive. To ensure proper installation, follow the guidelines provided. All cabling and distances are based on using 14 AWG, 4-conductor type cabling. In general, motors designed and built without phase separating insulation paper between motor windings should be classified as 1000VP–P insulation design. Section A: No Output Reactor or Terminator The following Table 4 lists the maximum cable lengths permitted when applying a 460V, 1305 drive to a 460V motor for motor insulation ratings of 1000V, 1200V, and 1600V without an output reactor or Terminator. Shielded and unshielded maximum cable lengths also are listed. Tables are based on operation at nominal line condition (480V). 1000V and 1200V Motor Insulation Ratings: Cable lengths listed in Table 4 are for operating the 1305 drive at a maximum carrier frequency of 4 kHz on motor insulation ratings of 1000V and 1200V. Consult the factory regarding operation above 4 kHz carrier frequency. Multiply listed distances by 0.85 for operation at high line conditions (above 480V). If the maximum cable length used exceeds the distances indicated, refer to Section B. 1600V Motor Insulation Ratings: Cable lengths listed in Table 4 are based on operating the 1305 drive at a maximum carrier frequency of 2 kHz on motor insulation ratings of 1600V. Consult the factory regarding operation above 2 kHz carrier frequency. Multiply listed distances by 0.55 for operation at high line conditions (above 480V). If the maximum cable length used exceeds the distances indicated, refer to Section B. The Allen-Bradley 1329-HR is representative of 1600VP-P insulation rating designs and is recommended in applications where long cable lengths are required.

The guidelines in Table 5 are required for proper drive and motor operation, or motor designs without phase–separating insulation paper between motor windings. Applications with non-inverter duty rated motors, with long lead lengths, require an output reactor or Terminator. An output reactor or Terminator helps reduce voltage reflection to the motor to levels which are less than the motor insulation rating. Table 5 lists maximum cable lengths that can be run when using an output reactor, or one of two available Terminators, for motor insulation ratings of 1000V, 1200V, and 1600V. Shielded and unshielded maximum cable lengths also are listed. When an output reactor is required, locate the reactor at the drive if possible. Consult the factory for applications which require mounting the reactor at the motor. 1000V and 1200V Motor Insulation Ratings: Cable lengths listed in Table 5 are for operating the 1305 drive at a maximum carrier frequency of 2 kHz on motor insulation ratings of 1000V and 1200V when used with an output reactor or Terminator. Consult the factory regarding operation above 2 kHz carrier frequency. Multiply listed distances by 0.85 for operation at high line conditions (above 480V). 1600V Motor Insulation Ratings: Cable lengths listed in Table 5 are based on operating the 1305 drive at a maximum carrier frequency of 2 kHz on motor insulation ratings of 1600V. Consult the factory regarding operation above 2 kHz carrier frequency. The Allen-Bradley 1329-HR is representative of 1600VP-P insulation rating designs and is recommended in applications where long cable lengths are required. Example: An existing installation includes a 2 HP, 1200V motor with a 84-meter (275-foot) cablelength requirement between the 1305 drive and the motor. What are the possible solutions to this installation? 1. Table 4 indicates that either an output reactor or a Terminator is required for this installation example. Consult Table 5 for output reactor, Terminator, and cable types. 2. Table 5 suggests these possible solutions: • Install a 1305 2-HP drive with an output reactor installed at the drive, and use unshielded cable. • Install a 1305 3-HP drive with an output reactor installed at the drive, and use shielded or unshielded cable. • Install a 1305 2-HP drive with a 1204-TFA1 Terminator, and use shielded or unshielded cable.

Reactors must have a turn-to-turn insulating rating of 2100 volts or higher. Reactors are not recommended for lightly loaded applications because over-voltage trips may result at low output frequencies.
