10. Power Switch
AC mains power ON/OFF switch.
11. AC Socket with inbuilt Fuse Holder
Connect to AC mains power with supplied AC power cord.
B. Battery Type Selection
GEL
: Gel sealed type maintenance free.
AGM
: AGM and VRLA sealed type maintenance free.
WET
: Automotive or Deep Cycle Lead Acid Batteries to which water can be added to, Calcium & Calcium-Calcium.
CALCIUM
: Calcium-Calcium type batteries are to be charged in this mode only when boost is required (15.5V). No load is
to be connected to the battery during this charge mode. Charge through one cycle only then set back to WET
charge setting.
B1. FLOAT VOLTAGE SELECTION
Follow the markings on the batteries for selecting Float Voltage setting. Choose 13.8V when in doubt or when operating in
Power Supply Mode.
B2. Recommended Battery Capacity
The following minimum AH capacity is a generalized suggestion as some batteries can take higher charge currents. Check with
battery manufacturers for charging details.
Charger Model
BC-1230 , 30A
BC-1240 , 40A
BC-1250 , 50A
Battery Capacity
100 AH - 300 AH
120 AH - 400 AH
150 AH - 500 AH
C. Battery Charger Installation and Connection
Observe warnings and safety precautions before operating the charger.
Check the battery condition, check the cell levels for wet type batteries and clean the battery terminals.
Secure the battery charger in a well ventilated area making sure the mounting surface is flat. The air intake is at the bottom and the
air outlet is at the back. Make sure both intake and outlet are not blocked.
Never place charger on top of a battery.
Plug in the AC mains and switch on the AC Power Switch. The Charger On LED and the Float LED should be on green indicating
the Charger is ready for charging.
Before connecting or disconnecting the charging cable, switch off the AC Power Switch and unplug the AC mains cord.
First connect the Red cable to Positive (+) Terminal of the Charger and then to Battery Positive (+) Terminal.
Second connect the Black cable to Negative (–) Terminal of the Charger then to Battery Negative (–) Terminal.
Make sure all the connections are tight and secure as voltage drops can occur.
Check again for correct charging settings.
