Chapter 2 Switch Installation
To wire the switch to a DC-input power source, follow these steps:
Locate the power and relay connector (see
Step 1
Figure 2-12
Identify the positive and return DC power connections on the connector. The positive DC power

connection is labeled V, and the return is the adjacent connection labeled RT. See
Measure two strands of twisted-pair copper wire (18-to-20 AWG) long enough to connect to the DC

power source.
Using an 18-gauge wire-stripping tool, strip each of the two twisted pair wires coming from each
Step 4
DC-input power source to 0.25 inch (6.3 mm) ± 0.02 inch (0.5 mm). Do not strip more than 0.27 inch
(6.8 mm) of insulation from the wire. Stripping more than the recommended amount of wire can leave
exposed wire from the power and relay connector after installation.

Step 5 Insert the exposed part of the positive wire into the connection labeled V and the exposed part of the
return wire into the connection labeled RT. See
Only wire with insulation should extend from the connector.
Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure
that no exposed portion of the DC-input power source wire extends from the power and relay
connector. Statement 122
