CONNECTIONS.
A. AC Line – Wire AC line voltage to terminals L1 and L2. Be sure jumpers J1A and

J1B are both set to the correct input line voltage 115 or 230 VAC. Connect ground
wire (earth) to green ground screw.
wire (earth) to green ground screw.
B. Motor.
1. Permanent Magnet (PM Type). Connect motor armature leads to M1(+) and
M2 (–). Be sure jumper J3 is set to the proper position “A90" for 90 volt DC
motors and “A180" for 180 volt DC motors. Note: 180 volt DC motors must be
used with 230 VAC line, 90 volt motors can be used with a 230 VAC or 115 VAC
line.

used with 230 VAC line, 90 volt motors can be used with a 230 VAC or 115 VAC
line.
Note: Motor performance and efficiency, including brush life, can be
adversely affected when using 90 volt motors with a 230 VAC line. Contact
motor manufacturer for derating information.

2. Shunt Wound Motors. Connect motor armature leads as above. Connect full
voltage shunt field leads (90 volt motors with 100 volt fields and 180 volt with
200 volt fields) to F+ and F-. Connect half voltage field leads (90 volt motors
with 50 volt fields and 180 volt motors with 100 volt fields) to F+ and L1.

MOTOR CURRENT.
Jumper J2 is factory set for 7.5 amp motors (7.5A). For lower amperage motors, place
J2 in the proper position. If motor amperage is less than 1.7 amps, use the 1.7 amp
position and readjust the IR and CL trimpots according to section VII, C and D on pages
28 and 29. Note: The factory setting for Current Limit is 150% of the nominal current
setting (e.g., if J2 is selected for 5 amps, the actual CL setting will be 7.5 amps). Note:
If the 10.0 amp setting (10.0A) is required, an auxiliary heatsink (KB P/N 9861) must be
used.

ENABLE.
A jumper must be connected between “EN” and “COM” terminals or control will not
operate. (See sec. V, G, page 22.)

Note: For the location of jumpers and trimpots, see fig. 12, control layout, on page 20.
5.
SPEED OR TORQUE MODE.
Jumper J5 is factory set for speed control operation (SPD). For torque control, set J5
to the “TRQ” position.
