Wiring
IMPORTANT
All wiring must agree with applicable codes,
ordinances and regulations.
Fig. 8 through 16 show schematics and typical
connections. Also refer to instructions supplied with other
system components.
IMPORTANT
To avoid electrical interference, which can
cause erratic performance, keep wiring runs as
short as possible and do not run wires adjacent
to the line voltage electrical distribution
systems. Use shielded cable (Belden type 8762
or equivalent for 2-wire and Belden type 8772 or
equivalent for 3-wire). The cable shield must be
grounded only at the controlled equipment
case.
