Step 1: Determination of Installation Location and Heat-dissipation Space
Determination of installation location: The controller shall be installed in a place with sufficient air flow
through the radiators of the controller and a minimum clearance of 150 mm from the upper and lower
edges of the controller to ensure natural thermal convection. Please see Figure 2-1: Mounting
CAUTION: If the controller is to be installed in an enclosed box, it is important to ensure
reliable heat dissipation through the box.
Step 2
：
Connect the system in the order of
❶
battery
❷
load
❸
PV array in accordance with Figure
2-
2,”Schematic Wiring Diagram” and disconnect the system in the reverse order
❸❷❶
.
CAUTION:
While wiring the controller do not close the circuit breaker or fuse and make sure that the
leads of "+" and "-" poles are connected correctly.
CAUTION:
A fuse which current is 2 times the rated current of the controller.
NOTE:
The controller is common negative one.
CAUTION:
Don’t connect the loads with surge power exceeding the ratings.
CAUTION:
Secure all wiring for mobile applications. Use cable clamps to prevent cables from
swaying. Unsecured
cables create loose and resistive connections which may lead to
excessive heating and fire.
WARNING:
Risk of explosion or fire! Never short circuit battery positive (+) and negative (-) or
cables.
