Overview; Field Wiring - Hussmann Super Plus Service Manual

Revised August 1, 1996

OVERVIEW

The scope of this section is limited to main
field wiring connections and to the control
panel. Hussmann's Super Plus
Panels feature custom wiring schematics. Most
of the common user choices are detailed in this
section. For a schematic of the control panel as
shipped, see the diagrams on the panel. T h e r e
are three:
– Compressor Control Circuit Diagram
– Defrost Diagram
– Power and Accessories Diagram.
The Fibertronic Circuit Boards are discussed
at length. Both explanation of Board layout
and a troubleshooting chart to determine
Board continuity are here. The Super Plus
System is available wired for 208-230/3/60 or
460/3/60 or other international voltages. In
any case, the control circuit is 120V. Refer to
the serial plate located on the control panel to
determine wire size (MCA) and overcurrent
protection (MOPD).

FIELD WIRING

Super Plus components are wired as com-
pletely as possible at the factory with all work
completed in accordance with the National
Electrical Code (NEC). All deviations
required by governing electric codes will be
the responsibility of the installer.
The lugs on the circuit breaker package in the
compressor control panel are sized for copper
wire only, with 75 C T H W insulation. A l l
O
wiring must be in compliance with governing
electrical codes.
