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 junction
box. Circuits must be sized for all case
components. See next page for wiring
routes.
MERCHANDISER ELECTRICAL DATA
Technical data sheets are included with
this manual. The data sheets provide
merchandiser electrical data, electrical
schematics, parts lists and performance data.
Refer to merchandiser serial plate or case
data sheets for electrical information.
WIRING COLOR CODE
Leads for all electrical circuits are identified by a colored plastic band: neutral wire for
each circuit has either White insulation or a White plastic sleeve in addition to the color band.

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.
IDENTIFICATION OF WIRING
Leads for all electrical circuits are identified
by colored plastic bands. These bands
correspond to the
color code sticker
(shown
below) located inside the merchandiser’s
raceway cover.
