Configuring the DC Output Connections
Before making any of the DC output connections, make sure you read and fully understand the DC Connection
Procedure below, including Section 3.2.
Select proper size for the DC wires using Table 4. If the distance between
the charger’s DC output and the battery/load exceeds 10 feet, use the Power Wiring Guide in Appendix C to
minimize the voltage drop across the wire distance.
NOTE:
It is recommended to use a battery disconnect breaker between charger and battery bank; helpful during
battery or charger maintenance.

Operation
3.1
A12B Startup
All equipment is shipped from the factory fully inspected and adjusted to manufacturer defined default values
based on the model number. Do not make any adjustments unless the equipment has been energized and the
settings have been determined to be incorrect.
3.2
Checking the Installation
Before attempting to start the A12B, check and verify the following:
Verify all connections are correct.
Check all terminations are tightened securely.
Check for any loose connection or unsecured components in the charger.
Check that the transformer input taps are set correctly for desired input voltage.
Verify the AC input and battery/load voltages match the voltages on the nameplate of the charger.
Verify AC feeder breaker matches charger input protection rating.
