Electrical Procedures
Electrical Considerations
CAUTION
Make sure all electrical connections at
components and terminal blocks are tight.
This will prevent burning of electrical
terminals and/or premature component
failure.
NOTE
Raceway covers will be shipped loose.
See the “General-UL/NSF I&S Manual” for
raceway cover installation and removal
instructions.
Case Fan Circuit
This circuit is to be supplied by an uninter-
rupted, protected 120V circuit. The case fan
circuit is not cycled.
Fluorescent Lamp Circuit
The standard case lighting system is 800MA
T-12 high output (HO) lamps. The standard
lighting is 1-row of horizontal canopy lights.
Defrost Information
See “General-UL/NSF I&S Manual” for
operational descriptions for each type of
defrost control.

WIRING DIAGRAMS
ELECTRICIAN NOTE - OVERCURRENT
PROTECTION
120V circuits should be protected by 15 or 20 Amp
devices per the requirements noted on the cabinet
nameplate or the National Electrical Code, Canadian
Electrical Code - Part 1, Section 28. 208V defrost
circuits employ No. 12 AWG field wire leads for field
connections. On remote cases intended for end to
end line-ups, bonding for ground may rely upon the
pull-up bolts.
The following wiring diagrams on pages 10,
11 and 12 will cover the N6DHP and N6DHPR
case circuits. The defrost and lighting circuits
are covered in the case circuit diagrams.
