Electrical Service Receptacles (When 
Applicable)

The receptacles located on the exterior of the merchandiser 
are intended for scales and lighted displays. They are not 
intended  nor  suitable  for  large  motors  or  other  external 
appliances.

BEFORE SERVICING

ALWAYS DISCONNECT ELECTRICAL

POWER AT THE MAIN DISCONNECT

WHEN SERVICING OR REPLACING ANY

ELECTRICAL COMPONENT.

This includes (but not limited to) Fans, Heaters

Thermostats, and Lights.

Field Wiring and Serial Plate 
Amperage

Field Wiring must be sized for component amperes printed 
on the serial plate. Actual ampere draw may be less than 
specifi ed. Field wiring from the refrigeration control panel to 
the merchandisers is required for refrigeration thermostats. 
Case amperes are listed on the wiring diagram, but always 
check the serial plate.

LED Driver Location

LED Drivers are located within the access panel (Electrical 
raceway) that runs the length of the rear of the case. Refer 
to Figure 3 on page 14.

Wiring Color Code

CASE MUST BE GROUNDED

NOTE:   Refer to label affi xed to case to determine the actual 

confi guration as checked in the “TYPE INSTALLED” 
boxes.

Electrical Circuit Identifi cation

Standard lighting for all models will be full length LED lamps 
located within the case at the top.

The  switch  controlling  the  lights,  the  plug  provided  for 
digital scale, and the thermometer are located at the rear 
of the case mullion.

The receptacle that is provided on the exterior back of these 
models is intended for computerized scales with a fi ve amp 
maximum load, not for large motors or other high wattage 
appliances. It should be wired to a dedicated circuit.
