1st step: Connect loads

Connect the load cable with the correct polarity of the right-hand side pair of terminals on the solar 
charge controller (with the lamp symbol). To avoid the presence of any tension on the cable/wires, please 
connect these first to the load before connecting them to the charge controller.

2nd step: Connect the battery

Connect the battery cables observing the correct polarity to the center pair of terminals (make sure you 
identify the battery marking/symbol on the controller casing!) of the PV charge controller. Pay greatest 
attention to polarity. Never, ever invert the plus+ and minus- poles). 

1)Should your system be nominal 12 Vdc, make sure the battery voltage is between the 

10

.0 and 15.

0

 Vdc 

voltage range; 

2)

for 24 Vdc nominal voltage, the battery voltage should be within the 20.0 to 3

0

.0 Vdc range

3)for 

36

 Vdc nominal voltage, the battery voltage should be within the

 31.0 to 42.0Vdc; 

4)for 

48

 Vdc nominal voltage, the battery voltage should be within the

 42.0 to 62.0Vdc. 

If the polarity is correct, the LCD on the controller will begin to display those.

3rd step: Connect the solar module

When connecting the PV-Module make sure to cover it from incident sun light. Double check the PV-
Module will not exceed the maximum permissible input current of the Charge Controller (please refer to 
the section Technical Data). Connect the solar module connection cable to the correct polarity of the left 
pair of terminals on the solar charge controller (with the solar module symbol).

4th step: Final work

Tighten all cables connected to the controller and remove all the remains around the controller (leaving a 
void of minimum 15 cm).

5.5 Grounding

Be

 

aware

 

that

 

the

 

positive

 

terminals

 

of

 

controller

 

are

 

interconnected

 

and

 

therefore

 

bear

 

the

If

 

any

 

grounding

 

is

 

required

always

 

do

 

this

CAUTION: 1

If

 

no
