Wiring
Use three-conductor, 20-guage or larger stranded wire to
connect the module to the control panel or to the NX-320E
power supply. Table 1 below shows the maximum wire length
for each gauge.
Table 1: Maximum wire length
Gauge Maximum wire length to panel
20 gauge 10 ft. (3.1 m)
18 gauge 50 ft. (15.2 m)
16 gauge 100 ft. (30.5 m)
Refer to Figure 2 to identify the wiring terminals of the module
and wire from these terminals to the main control panel or NX-
320E power supply based on Table 2 below.
