*AWG, Cu wire only.
A. AC Line – Connect AC line to
terminals L1 and L2. (See fig
3.)
B. Ground – Be sure to ground
(earth) the control via green
screw located on chassis
C. Motor Armature – Connect
motor armature to terminal M1 and
M2. (See fig. 3)
D. Field (For Shunt Wound motors
only) – Do not use F+ and F-
terminals for any other motor type. Connect motor shunt field to terminals F+ and F- for
180VDC motors with 200VDC fields. For motors with half voltage fields, 180VDC motors
with 100VDC fields, connect field to terminals F+ and L1 (see fig 4A and 4B). See table
5 for summary of Field Connections.
CAUTION – Shunt-Wound motors may be damaged if field remains connected
without motor rotating for an extended period of time. To remove field voltage from
motor, disconnect AC line.

E. Main Speed Potentiometer – The main speed potentiometer can be connected in several
ways using terminals "10," "11," "12" and "13." ( A 5K ohm potentiometer is supplied with
control. A 10K potentiometer can also be used.) [WARNING: Terminals 10, 11, 12 and
13 are not isolated from AC line. Do not ground (earth).]
i. Unidirectional operation only – Connect potentiometer to terminals "10," "12," "13" for
forward direction. (To operate in reverse direction, connect to "11," "12," "13.")
