KPC Capacitor Bank
Installation Instruction
INPUT
When installing the KPC capacitor
bank on the INPUT side of the Variable
Frequency Drive (VFD) or induction
motor, please use the following guidelines
when wiring the unit:
e KPC capacitor bank is wired in
parallel with the load.
Refer to NEC wiring practices for
appropriate wire sizes for your application.
Power Wiring: Only use 75°C
copper conductors unless the wire
connector is marked for Al/Cu, then the
use of aluminum wire is permitted.
In standard 40°C ambient or less
installations, a clearance of 3 inches on
all sides of the capacitor bank and its
enclosure is recommended for assisting in
heat dissipation and ample wire bending
space.
ese capacitors are designed to be
panel mounted.
