Attaching the Power Connectors to the Switch

To attach the power connectors to the front panel of the switch, follow these steps:

Step 1 Insert one power connector into the DC-A receptacle on the switch front panel, and the other into the DC-B receptacle. See Figure 2-17.

Warning Failure to securely tighten the captive screws can result in an electrical arc if the connector is accidentally removed. Statement 397

Warning When you connect or disconnect the power and/or alarm connector with power applied, an electrical arc can occur. This could cause an explosion in hazardous area installations. Be sure that all power is removed from the switch and any other circuits. Be sure that power cannot be accidentally turned on or verify that the area is nonhazardous before proceeding. Statement 1058
