Wire 24 Vac power
After the termination module is mounted in the selected location, wire
24 Vac power to the termination board. Table 5 shows the specifications
for power wiring.
IMPORTANT
The 24 Vac wire conduit may not contain input/output or communica-
tion wires. Failure to comply may cause the Tracker controller to mal-
function due to electrical noise.
1. Route input wires into the termination module through the conduit
box or any of the conduit access openings designated for input and
communication wiring (Figure 12 on page 19).
2. Wire the two 24 Vac power input wires and the ground wire to the
controller 24 VAC terminals (Figure 14 on page 24).
