Panel Identification
Each FRENIC-HVAC Combination VFD has a nameplate label, like the example
pictured above, which contains important information about the panel. This label is
located on the inside of the hinged door or cover of the enclosure.
CAUTION
•Refer to the nameplate label to determine the panel input voltage and current
requirements prior to installation and wiring.
•Refer to the nameplate label for the correct wiring diagram (Elementary Drawing).
•Sizing of field wiring conductors should be based upon the current ratings listed on
the nameplate label.

Installation
CAUTION
The FRENIC-HVAC Combination VFD should be located:
•Away from flammable or combustible liquids, gases, and other materials
•Away from sources of severe dust, metal shavings, or other particulate
material
•Away from corrosive liquids, spray, or mist
•Away from sources of heat
•Where the ambient temperature will remain between -10°C (14°F) and 40°C
(104°F)
•Where the elevation is 3300ft or lower, above this level requires derating the
current
Wall-mount panels must be mounted to a surface that is capable of supporting the
weight of the panel.
Refer to the Outline/Layout drawing that shipped with the panel for required clearances.
Routing of field wiring should be planned in coordination with choosing a mounting
location.
Disconnect – Motor branch circuit protection to be provided by customer/others per table
on next page.

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.

Power Wiring (Motor Leads)
The customer power output (motor leads) wiring connects directly to the U, V, and W
terminals on the drive. The following picture shows wiring connections that are available
on FRENIC-HVAC drives:
** Note **
The enable jumpers (PLC to EN1 & EN2) have been removed from the following pictures
for clarity of illustration. DO NOT remove these jumpers unless specific use of these
terminals is required for the application. Please reference the FRENIC-HVAC User’s
Manual (24A7-E-0069*) for details on utilizing EN1 & EN2 terminals.
