DC Power
The OAG2400-ACDC and OAG1000-ACDC SafeGuard Controllers provide a DC power
input connector that allows you to use a 48-VDC power source as backup for the system.
You must provide the appropriate cable for use with the connector.
To attach the connector to a three-wire cable, follow these steps:
1
Strip 1/8 inch from the end of each wire.
2 Loosen the retaining screws along the side of the connector (see Figure 11 ).

3 Insert each wire firmly into the connector, and tighten the retaining screw to
secure the wire. Make sure that no wire is exposed beyond the connector housing.
With the retaining screws at the left, the order of wires from top to bottom is red,
black, and green.
NOTE: We recommend that you provide a 10-A fuse on your external DC
connection to safeguard against connecting the power source with the
incorrect polarity.
