5 7 34 Insert (under Installation/AC Connections):
Connect appropriate end of charger power cable to AC supply. The AC
feeding the charger should be the same source feeding the load power
supply.
Proceed to the next section, AC Voltage Selection, before
connecting other end of charger power cable to charger.

5.0 OPERATION
5.1 Startup
Ensure all power and alarm connections are secure and the AC input voltage selection jumpers are set correctly
(see AC Voltage Selection under Installation Instructions for details). Re-install the back cover and plug the AC
cable into the rear of the unit (drawing 010-519-06, page 2).
The battery fuse(s) should be installed after AC power has been applied to the charger and the POWER ON LED
is illuminated. Although this procedure is not critical it will ensure a more controlled charging of the output filter
capacitors, and power up of the control circuitry in the charger.
To properly start up and test the battery reverting charger the DC connections to the load, AC connections for
both the charger and for the connected load must be connected.
Turn on the AC power to both the charger and the connected load. The load will be powered by its own internal
supply and the charger will be charging the system battery.
5.1.1 Test Transfer Function
Remove AC power from both the battery revert charger and the connected equipment. With the AC removed the
charger will connect the battery to the load instantly.
Reconnect AC power to both the charger and the connected load and the charger will disconnect the battery from
the communications equipment and will start recharging the battery. The communications equipment will now be
powered from its own internal power supply.
Note: Due to the nature of the transfer sensing circuitry section 5.1.1 is the only effective method of testing the
transfer circuitry. Bench testing the charger without the connected load will not effectively test the transfer function.
5.2 Shutdown
Ensure the battery is not connected to the load (the ON BATTERY LED(s) are off). Remove the battery fuse(s).
Unplug the AC cable from the rear of the charger.
5.3 Default Operating Mode
The charger’s default operation is in Float mode. The POWER ON and FLOAT MODE LEDs are illuminated.
To change from FLOAT mode to EQUALIZE mode press and hold the FLOAT/EQUALIZE Mode button for 3
seconds. When the charger changes to EQUALIZE mode the output voltage will increase (see Battery Output
Voltage specifications). Pressing this button again will revert to FLOAT mode (no 3 second delay).
NOTE: Refer to Sections 3.3 and 3.4 regarding Equalize mode, controls and other features of charger operation.
5.3.1 Typical System (Transfer Process)
During AC power, the purpose of the charger is to charge and maintain the battery bank in a Float mode with
automatic equalization every 30 days. The battery bank becomes the source of power to the load when AC power
fails, and the charger is turned off.
Under AC power fail condition, the automatic revert circuit detects this condition and connects the load to the
battery for backup battery operation. After normal AC power is restored, the battery and charger are automatically
disconnected from the load and, at that time, the charger will begin to recharge the battery.
