Chapter 2 – Installation

Connecting the Motor Cable
1.
Connect the MS connector on the motor cable to the mating connector on the
motor. (If you use a non-Compumotor motor, see
Appendix B for information.)
2.
Remove the clear plastic cover from the drive terminals. Connect the motor cable’s
green/yellow wire to the drive terminal with the
symbol. This connects the
motor’s protective conductor terminal to the drive’s safety earth.
3.
Connect your motor cable’s phase wires 1, 2, and 3 to the drive’s U, V, W terminals,
respectively, as shown in the drawing below.
WARNING
The drive’s barrier strip terminals are at hazardous voltages when power is
applied to the drive, and up to 30 seconds after power is removed. Lower
voltages may still be present for several minutes after power is removed.
Reinstall the clear plastic terminal cover after you make connections.
4.
Secure the cable to the drive by placing the exposed cable shield in the saddle
clamp on the bottom of the drive (GV6K-H20n/H40n: R-Clamp on heatsink). Make
the loop of cable between saddle clamp and drive terminals as short as possible.
Connecting the Motor Feedback Cable
Compumotor’s motor feedback cable with the GS or GB option has an MS
connector on one end, and a 26 pin connector on the other end.
1.
Connect the MS connector on the motor cable to the mating connector on the
motor.
2.
Connect the 26 pin connector on the motor cable to the drive’s MOTOR FEED-
BACK connector.
3.
Tighten the jack screws on the connector housing to secure the connector to
the drive.
Secure the Motor
1.
If your motor is not permanently mounted, clamp it securely in place during this
Express Setup procedure.
The next drawing illustrates these connections.
