8.1 Connecting External Batteries
Do not connect an external battery
charger to the D6600.
Use the terminal on the rear panel to connect an
external DC power source. During AC power outages,
the external DC source supplies power to the receiver.
Use a 12 VDC lead-acid battery for external back-up
power.
Only use approved stationary standby batteries for UL
applications. Battery wiring must run from the receiver
through the UL Listed rack, exit the rack through a
conduit connection, and terminate at a UL Listed
battery enclosure suitable for the size and number of
batteries used for UL applications.
