PREPARING THE CHARGER FOR OPERATION
Selecting AC input voltage
The charger is
pre-set to operate from input AC voltage of 120 VAC, 60 Hz
.
To operate the charger from AC input voltage of 230 VAC, 50 Hz, change the internal
setting as follows :
1. Remove the 4 screws on the ammeter side of the top cover
2. Gently slide the top cover out by 2 to 3 inches. (
Caution !
The top cover will be
restrained from fully sliding out by the wires connecting the ammeter, LED and
the fan )
3. Locate the jumper wire with a quick female disconnect. In the pre-set condition,
it is connected to the male vertical pin marked “115 V”. Pull this female discon-
nect upwards to disconnect from the “115 V” position. Connect this to the male
vertical pin marked “230 V”
4. Replace the fuse with the fuse recommended for 230 VAC operation ( See fuse
rating at page 12)
5. Replace the AC plug of the power cord with a suitable 3 pin grounded plug to
mate with the 230 VAC outlet. (
Caution !! The new plug should have 3 poles
i.e. Line ( L ) , Neutral ( N ) and Earth ground. Color code for the power
cord conductors is : Line ( L ) - Black , Neutral ( N ) – White and Earth
ground – Green )
Selecting the Type of Battery and Charging Stages
The Float Voltage and Boost Voltage (Also called Absorption or Overcharge Voltage ) of
different types of Lead Acid Batteries are different. Also, when a charger is used to charge
a battery and simultaneously supply a load , the Boost Stage is required to be disabled to
prevent overcharging of the battery . A
Dip Switch
is provided on top of the output
terminals for selecting the battery type and for disabling the Boost Stage when charging
loaded batteries. The following selections can be made with the help of the Dip Switch.
CAUTION ! (Do not change the Dip Switch setting when the charger is operating.
Always change the Dip Switch setting when the charger is off , i.e. after disconnect-
ing the charger from the AC input power )
NOTE : The voltages are for a temperature of 80 Degrees F
