Motor Connections
The 170-101-0212 drive supplies motor voltage from A+ and A- terimnals. It is assumed that
when A+ is positive with respect to A-, the motor will rotate clockwise (CW) while looking at the
output of the shaft protruding from the front of the motor. If this is opposite of the desired
rotation, reverse the wiring of the A+ and A- terminals.
Power Input
Connect the AC power leads to terminals L1 and L2, or to a double-pole single-throw master
power switch (recommended).
Line Fuse
Wire an external line fuse between the stop switch (if installed) and the L1 terminal.
Speed Potentiomenter Connections
Speed adjustments are supplied by speed potentiometers connected to J1 and J2 (Factory
supplied pot kit includes two sets of potentiometer hardware).
