S3C DISPLAY MODULE
5.2.1 MOUNTING
Mount the Display Module in an indoor location on top of or near the refrigerated display case; outside of the conditioned
space. After a location is determined, carefully cut out a 2.8” X 1.14” rectangle in the panel/bulkhead. The bulkhead
thickness must be less than 0.31”. Remove the fastening clips from the Display Module and slide the display into the cut
out. Slide on the fastening clips on both sides and push up against the bulkhead. Ratcheting sounds should be heard
to ensure rubber knife edge on the Display Module seal tightly against the outside of the bulkhead. Attach power and
communication wiring to the back of the Display Module.
5.2.1.1 WIRING
With Case Controller unpowered, carefully route the power and communication wiring from the Display Module to the
Case Controller. Use 22/2 shielded twisted pair (Belden 8723 or equivalent). Attach one end of the shield to earth ground.
Wire designations are located on the back of the Display Module. Maximum torque on the screw terminals is 3.5 in.-lb.
Carefully tug the leads to ensure they are secure. Ensure that all wiring is properly fastened and away from sharp edges or
moving objects. Do not route the Display Module wiring in the same conduit as 120VAC or greater. See the following figure.
