Electrical Connections - IEC Vertical F*C Series Installation, Operation & Maintenance Manual

Electrical Connections

The unit serial plate lists the unit electrical characteristics
such as the required supply voltage, fan and heater
amperage and required circuit ampacity. The unit wiring
diagram shows all unit and field wiring. Since each project
is different and each unit on a project may be different, the
installer must be familiar with the wiring diagram and serial
plate on the unit BEFORE beginning any wiring.

Make sure all field electrical connections are in accordance
with unit wiring diagram and all applicable national and
local codes. The type and sizing of all wiring and other
electrical components such as circuit breakers, disconnect
switches, etc. shall be determined by the individual job
requirements. Verify conductor size is suitable for the
distance to the equipment connection and will support
the equipment electrical load. All installations including
field wiring shall be made in compliance with all governing
codes and ordinances. Compliance with all codes is the
responsibility of the installing contractor.
All components furnished for field installation by either
the factory or the controls contractor shall be located and
checked for proper function and compatibility. Check
all internal components for shipping damage. Check all
electrical connections within the unit control box and
accessories and tighten if necessary.
Any devices such as fan switches or thermostats that have
been furnished from the factory for field installation must
be wired in strict accordance with the wiring diagram
that appears on the unit. Failure to do so could result in
personal injury or damage to components, and will void all
manufacturer warranties.
Never control fan motor(s) by any wiring or device other
than the factory-supplied switch or thermostat/switch
combination unless prior factory authorization is obtained.
Fan motor(s) may be temporarily wired for use during
