BATTERY
THE RED LED IS OFF
The DC side fuse may have blown due to wrong polarity of battery connection. Ensure positive of the battery is
connected to the positive of the charger and the negative of the battery is connected to the negative of the charger.
Check the DC side fuses inside the charger and replace, if blown
The battery may be shorted. In this condition, the unit is shut down by the short circuit protection circuit. Remove
the battery connection. If the LED now comes on, the battery is shorted. If the LED still does not come on, check
there is AC power in the receptacle. If there is power, check the AC side fuse inside the unit . If the fuse is not
blown, call technical support.

The unit is also feeding external circuit (s) in parallel with the battery. The current drawn by the external
circuit(s) is preventing the unit from reverting to the float condition (see under caution on page 4). Disconnect
the external load when charging battery.
