Warning

Be sure to read, understand, and follow all safety instructions.

Only qualied electricians should carry out all electrical installation and maintenance work on capacitor bank.

All wiring must be in accordance with the National Electrical Code (NEC) and/or any other codes that apply to the installation site.

Disconnect all power before working on the equipment. Do not attempt any work on a powered capacitor bank.

e capacitor bank and other connected equipment must be properly grounded.

e terminals and connected cables are at a dangerously high voltage when power is applied.

Field Wiring Information

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.

3-phase and 1-phase, 600 Volt Class UL Listed; File E-116124 kVar rated device Ambient Temperature: 40°C

Wiring: KPC has 3 power terminals, 1 for each

phase of 3 phase circuit. Wire in any order.
