OPERATING INSTRUCTIONS 

1. Connect 

power supply 
 
Red lamp 
lights up 

Whilst not necessary for proper operation it is good practice to 
shield the charger from rain and direct sunlight whenever possible.  
Free airflow over the unit should be ensured at all times.  
 
Choose type of power supply (AC or DC). 
 
Connect the power supply cable for 12/24VDC or the power supply 
cable for 230VAC to the battery charger.  
 
Connect the power cable to the power source. 
 
The red lamp on the charger should light up.  
 

2. Connect 

battery  
 
Green lamp 
lights up 

Connect battery/batteries to the charger. 
 
The green lamps should light up for all connected batteries. 
The red lamp goes out when first battery is connected.  
 
All connected batteries will be charged simultaneously and 
independently of one another. 
 

3. Battery 

charged 
 
Green lamp 
flashes 

A battery is fully charged if the green lamp flashes. 
 
The charged battery may be replaced immediately by another. 
Charged batteries may alternatively be left connected to the 
charger. 
 

 Fault 

indication 

The red lamp alone will flash if a fault develops within the charger or 
if the input power source voltage is too low or too high.  
 
The red and green lamps both flash quickly if a battery fault is 
detected. (Typically this warning indicates excessively low battery 
voltage or unexpectedly high internal battery resistance.)  Batteries 
which cause the display of this warning should be replaced and 
must not be subjected to further attempted charge cycles. 
 

Automatic protection of discharging 12V supply battery in the 
vehicle. 

The charger will automatically be turned off if the 12V DC 

supply voltage in the vehicle becomes too low. The charger will 
flash the red lamp slowly.
