FIG. 6 – AC LINE AND
ARMATURE CONNECTION
A. AC Line – Connect AC Line to terminals L1 and
L2. (Be sure jumpers J1 and J2 are set to match
the AC Line voltage used.) (See table 5, p. 4.)
B. Motor Armature – Connect motor armature to
terminal M1 and M2. (Be sure jumper J4 is set to
match motor voltage.) (See table 5, p. 4.)
C. Ground – Be sure to ground (earth) control via
green screw located on chassis. Do not ground
any other terminals.
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 90VDC motors with 100VDC fields and
180VDC motors with 200VDC fields. For motors
with half voltage fields, 90VDC motors with
50VDC fields and 180VDC motors with 100VDC
fields, connect field to terminals F+ and L1. See
table 7 for summary of field connections.
CAUTION – Shunt-Wound motors may be
damaged if field remains powered without
motor rotating for an extended period of time.
