Plug-In Horsepower Resistor
®
Select the correct Plug-In Horsepower Resistor® (supplied separately), according to armature
voltage and motor horsepower information in Table 4-2. Install the correct Plug-In Horsepower
Resistor
®
as shown in Figure 2-3. (See note below.)
Note:
The Armature Fuse is supplied with the Plug-In Horsepower Resistor® Kit. See Table 4-3 for
Catalog No. and ratings.
2.6 Permanent Magnet (PM) Motor Armature Connection
Connect the motor armature to Terminals “A+” and “A-” of the Barrier Terminal Block, as shown in
Figure 2-2.
2.7 Motor Field (Shunt Wound Motors Only)
Connect the motor field (of the shunt wound motor) to the Barrier Terminal Block. For full voltage
field, use Terminals F+ (positive) and F- (negative). For half voltage field, use Terminals F+ (positive)
and L1 (negative). See Section 4.
CAUTION! Do not connect motor armature leads to Terminals “F+” and “F-”. Do not use
Terminals “F+” and “F-” for any purpose other than to power the field of a shunt
wound motor. Shunt wound motors may be damaged if the field remains
energized without armature rotation for an extended period of time.
