7. 

INITIAL SET UP AND CONNECTION 

 

1. 

Leave the output terminals disconnected. 

2. 

Connect a 48V battery to the input terminals.   

 

DOUBLE CHECK FOR CORRECT POLARITY BEFORE CONNECTION. 

3. 

Programming Procedure using the SET button 

4. 

Press and hold the SET button until shows up and display flashes. 

5. 

Flashing digits indicate unit is in programmable mode. 

 

Otherwise repeat step 4 to get to programmable mode again. 

6. 

Each short press will increase the output voltage setting by 0.2V steps-> 15.0V -> CHA (Charger Mode).

 

And then back to 12.0V as shown in the following cycle chart. 

 

 

6. 

Stop at the desired Output Voltage or at the 

  if you select to set to battery charger mode. 

7. 

After few seconds, the display will stop flashing to confirm the selected setting.

 

The unit will then               

operate in new set voltage output or as a battery charger. 

8. 

Now you can connect the output terminals to a 12V device or to a 12V battery. Always double check for 
correct polarity.
