INSTALLATION INSTRUCTIONS
CAUTION
: This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the Installation Instructions, may cause interference with radio communication. It has been tested and
found to comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules, which are
designed to provide reasonable protection against such interference when operated in a commercial environment.
Operation of this equipment in a residential area is likely to cause interference, in which case, users at their own expense
will be required to take whatever measures may be required to correct the interference. Any unauthorized modification of
this equipment may result in the revocation of the owner’s authority to continue its operation.
BEFORE INSTALLATION
All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring diagrams.
Digital Wall Module (DWM) wiring can be sized from 16 to 22
AWG (1.5 to 0.34 mm
2
), depending on the application. The
maximum length of wire from a device to a wall module is
164 ft (50 m). Twisted pair wire is recommended for wire runs
longer than 100 ft (30.5 m).
CAUTION
EMI Noise Introduction.
Risk of erratic system operation.
Keep wiring at least one ft (305 mm) away from large
inductive loads such as motors, line starters, lighting
ballasts and large power distribution panels. During
installations, try to avoid areas of high EMI noise.
Run wall module wiring separately from 50 Vac or
greater power wiring.
