Wiring Overview - Fuji Electric FRENIC-HVAC Series Instruction Manual

Wiring Overview

The FRENIC-HVAC Combination VFD must be connected to an input power source, a
motor (output power), ground, and control may be local or by using remote devices such
as switches, potentiometers, etc....
WARNING
•
Wiring should be performed by a qualified electrician using standard practices as
specified by local and national codes.
•
Always make sure the input power source is OFF before connecting or disconnecting
any power input, output, or control wiring.
•
Ground the panel, as specified by local and national codes, using the provided
grounding lugs.
•
Make sure that the input power source (phases, voltage, and current capacity)
matches the requirements of the panel as stated on the nameplate.
•
Never connect line voltage to the drive output terminals (U, V, and W).
•
IF not using the provided conduit holes, then when making holes for conduit fittings,
be sure to cover the drive and other components to protect them from metal
shavings.
CAUTION
•
All field wiring should be copper with a minimum insulation rating of 75°C.
•
Sizing of field wiring conductors should be based upon the current ratings listed on
the nameplate label, in accordance with local and national codes.
Refer to the Elementary diagram that shipped with this panel and the torque table in this
Instruction Manual.
Refer to the diagrams on the following pages for general component layout and for
general routing of power input, power output (motor connections), and control wiring for
your panel. Power input wiring should be routed away from power output wiring, and
both should enter the panel from separate conduit. Control wiring should be routed away
from power wiring, and should enter the panel from separate conduit.
Refer to the following section Control Wiring for descriptions of the control connections.
