This chapter provides instructions on wiring output contactors, motor overload
protection, and output wiring to the motor.
6.1 Installing Output Contactors (Optional)
Output contactors provide a positive means of disconnecting the motor from the drive.
If the application requires the use of output contactors, contact Reliance Electric for
assistance.
6.2 Installing Mechanical Motor Overload Protection
(Optional)
To provide the motor with overload protection, local, national, and international codes
(e.g., NEC/CEC) require one of the following:
•
•
The Motor Overload Enable parameter (P.040) can be used in place of thermal motor
overload relays in single motor applications. Note, however, that temperature
measuring devices integral to the motor are the best way to thermally protect AC
motors under all conditions. Parameter P.040 must be enabled to provide overload
protection. Refer to the GV3000/SE Software Start-Up and Reference manual for
more information.
In multiple-motor applications (V/Hz regulation only), each motor must have its own
user-supplied overload protection.
6.3 Installing Output Wiring from the Drive Output
Terminals to the Motor
Use the following steps to connect the AC output power wiring from the drive to the
motor:
Step 1. Wire the three-phase AC output power motor leads by routing them

A motor thermostat be installed internal to the motor.
An electronic thermal motor overload relay, sized to protect the motor, be installed
between the motor and the drive's output terminals.
according to drive type. Refer to figures 4.1 to 4.7. Tables 3.3 to 3.8 contain
the recommended power wiring sizes.
Do not route more than three sets of motor leads through a single conduit.
This will minimize cross-talk that could reduce the effectiveness of noise
reduction methods. If more than three drive/motor connections per conduit
are required, shielded cable must be used. If possible, each conduit should
contain only one set of motor leads.
