PCD7.LR-TR40 and PCD7.LR-TR42
LCD and non-LCD Wall Modules
BEFORE INSTALLATION
Fig. 1. PCD7.LR-TR42
Mount the wall module on an inside wall approximately 1372 mm
from the floor (or in the specified location), to allow exposure to
the average zone temperature. Do not mount the wall module on
an outside wall, on a wall containing water pipes, or near air ducts.
Avoid locations that are exposed to discharge air from registers or
radiation from appliances, lights, or the sun.
The wall module can be mounted on a wall, on a standard utility
conduit box using 3.5 mm screws or on a 60 mm wall outlet box
(see Fig. 3). When mounting directly on a wall, use the type of
screws appropriate for the wall material.
CAUTION
Erratic System Operation Hazard.
Failure to follow proper wiring practices can intro-
duce disruptive electrical interference (noise).
Keep wiring at least one foot away from large inductive loads such
as motors line starters, lighting ballasts, and large power distribu-
tion panels.
Shielded cable is required in installations where these guidelines
cannot be met.
Ground the shield only to the grounded controller case.
IMPORTANT
All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring dia-
grams.
• For information on Sylk bus distance limitations,
see Table 1 on page 2.
• All wiring is polarity insensitive.
