II. PLUG-IN HORSEPOWER RESISTOR®
A Plug-In Horsepower Resistor® (PHR) must be
installed for the KBWS to operate. Select a Plug-
In Horsepower Resistor® to match the motor
characteristics to the control. See Figure 3 and
Table 3 on page 12. The PHR plugs into the two
female terminals that are provided on the KBWS.
Plug-In Horsepower Resistors® are supplied
separately by your distributor.
