The unit can operate from an AC power source (AC100-240V), built-in batteries or an external DC power
source (DC12/24V).
Whenever the power cord is not connected to a power outlet, or the power supply from an AC
power source (AC100-240V) or an external DC power source (DC12/24V) is shut down, the
power is automatically supplied from the built-in batteries.

Power Outlet and Grounding
The following power supply ratings are available. Do not connect the unit to any other power
source.
Voltage - AC100-240V; power consumption - 220VA; frequency - 50/60Hz; operating voltage
range - AC100-240V±10%
Voltage - DC12V; current - 13A; operating voltage range - DC12.4-15.1V
Voltage - DC24V; current - 6.5A; operating voltage range - DC24.8-30.3V
The power outlet should be located near the unit in order to prevent accidental contact with a
trailing power cord. Use a separate power outlet for each unit.
Do not put many loads on one power outlet.
In order to complete the ground connection, only connect the power cord to a correctly ground-
ed 3-prong power outlet.
Do not operate the unit if you have any doubts about its ground connection.
Peripheral electrical equipment must also be grounded securely.
