Chapter 2 Switch Installation
Connecting to Power
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 wire can leave
exposed wire from the power connector after installation.
Figure 2-4 Stripping the Power Connection Wire
Step 5
Remove the two captive screws that attach the power connector to the switch, and remove the power
connector. Remove both connectors if you are connecting to two power sources. See Figure 2-5.
Figure 2-5 Removing the Power Connectors from the Switch
Step 6
On the power connector, insert the exposed part of the positive wire into the connection labeled “+” and
the exposed part of the return wire into the connection labeled “–”. See Figure 2-6. 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 connector(s)
or terminal block(s).
