AC Side Fuse Blows As Soon As
Power Is Turned ON
The AC input is selected for 120 VAC but
the unit is plugged into 230 VAC. Always
check that the charger is set for the cor-
rect AC mains voltage. If the AC input
voltage is correct, the charger is defective.
Call Technical Support.
DC Side Fuse Blows As Soon
As The Battery Is Connected
Wrong polarity of the 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.
SYMPTOMS WHEN THE CHARGER
IS POWERED AND IS BEING USED
AS A DC POWER SUPPLY/UPS
The Voltage Drops When Load Is Switched On
The load is trying to draw current more
than the current limit value of the charger
(the current limit value is the maximum

specified charging Amps). Once the load
current reaches the current limit value,
the current limit circuit is activated and
the output voltage drops. Some loads
like motors, compressors, incandescent
lamps, halogen lamps, heating elements,
relays, coils, capacitors etc. draw very large
inrush/starting currents which may reach
up to 10 times their normal operating
currents. Ensure that the starting / inrush
current or the maximum operating cur-
rent of the load is lower than the current
limit value of the charger.
