MERCHANDISER ELECTRICAL DATA
Merchandiser data sheets for specific models are
shipped with this manual. The data sheets provide
case electrical data, electrical schematics, parts
lists and performance data. Refer to the merchan-
diser data sheets and case serial plate for electrical
information.
FIELD WIRING
Field wiring must be sized for component amperes
stamped on the serial plate. Actual ampere draw
may be less than specified. Field wiring from the
refrigeration control panel to the merchandisers is
required for defrost termination thermostats and for
optional refrigeration thermostats. When multiple
merchandisers are on the same defrost circuit, the
defrost termination thermostats are wired in series.
ALWAYS CHECK THE SERIAL PLATE FOR
COMPONENT AMPERES
.
ELECTRICAL CONNECTIONS
All wiring must be in compliance with NEC and
local codes. All electrical connections are to be
made in the electrical raceway on the serial plate
side of the case (front).
IDENTIFICATION OF WIRING
Leads for all electrical circuits are identified by
wire insulation color or colored plastic bands.
These bands correspond to the color code sticker
(shown below) located inside the merchandiser’s
raceway.

WIRING COLOR CODE
Leads for all electrical circuits are identified by wire insulation color or a
colored plastic band: neutral wire for each circuit has either White insu-
lation or a White plastic sleeve in addition to the color band.
