Quick Set-Up Guide

Connect to the Power Supply

If the power supply does not have a fuse
on the output or some kind of short cir­cuit current limiting device, a 4 amp fast
acting fuse should be installed in line
with the “+” power supply lead.

Connect the motor power supply “+” ter­minal to the drive terminal labeled “V+”.
Connect the power supply “-” to the drive
terminal labeled “V-”.

Be careful not to reverse the wires.

Connecting to a Motor

Connect the drive to the motor.
Four lead motors can be connected
in only one way. If using a non
MOONS’ motor, consult the motor
specs for wiring information.
