Power
Alerts when utility power is available to a de-energized panelboard.
When the main circuit breaker in a generator-ready load center, manual transfer panel or other panel, must be
turned OFF during a power outage, in order for a standby generator to supply power to emergency circuits, the
PowerBACK will sound a 100dB audible alert as soon as utility power is restored. The load center or panelboard may
then be returned to utility power and the PowerBACK disarmed.
To Install: Mount the PowerBACK in any 1/2" KO within 20 inches of the main breaker. Coil the flexible 8-inch volt-
age-sensor around either of the hot legs ahead of the main breaker and connect the ground wire.
PROFESSIONAL INSTALLATION RECOMMENDED.
To Activate: Switch the main breaker to the OFF position. Turn the PowerBACK switch to the ON position. The green
"System Armed" light will illuminate. When power returns to the panelboard, a 100dB alert will sound. Return main
breaker to ON position and switch the PowerBACK to the OFF position.
