Chapter 2 Switch Installation
Verifying Switch Operation
To wire the switch to a DC-input power source, follow these steps:
Step 1 Locate the power and relay connector (see Figure 2-12).
Figure 2-12 Power and Relay Connector
Step 2 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 Figure 2-12.
Step 3 Measure two strands of twisted-pair copper wire (18-to-20 AWG) long enough to c onnect to the DC
power source.
Step 4 Using an 18-gauge wire-stripping tool, strip each of the two twisted pair wires coming from each
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 wir e can leave
exposed wire from the power and relay connector after installation.
Figure 2-13 Stripping the Power Connection Wire
Step 5 Insert the exposed part of the positive wire into the connection la beled V and the exposed part of the
return wire into the connection labeled RT. See Figure 2-14. Make sure that you cannot see any wire lead.
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.
