Wiring the DC Inputs

The 7705 SAR-F has a standard, dual-feed, terminal block attached to the front of the
chassis. The terminals are the DC power feed points for source voltage from the DC circuit.
For redundant power configurations, you must use both DC power feeds (one for each pair
of power terminals).
To connect power cables to the terminal block, attach a ring lug to each power cable at the
router end, as shown in
7705 SAR-F Installation Guide
Ensure that all power is OFF from the DC circuit. Locate the circuit breaker on the panel
board that services the DC circuit and switch the circuit breaker to the OFF position. For
extra safety, you can tape the handle of the circuit breaker in the OFF position.
When wiring the unit, the chassis ground connection must always be made first and
disconnected last.
