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
NOTE: 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
.
NOTE: While wiring the controller do not close the circuit breaker or fuse
and make sure that the leads of "+" and "-" poles are connected correctly.
NOTE: A fuse which current is 1.25 to 2 times the rated current of the
controller must be installed on the battery side with a distance from the
battery not greater than 150 mm.
NOTE: If an inverter is to be connected to the system, connect the inverter
directly to the battery, not to the load side of the controller.
Step 3
：
Grounding
As the TRIRONN series is a common negative controller, the negative poles of the PV
array, battery and load can be grounded together.
NOTE: The controller can also be used in a common positive system. In this
case, the negative poles of the controller, PV and load can’t be grounded
together, but only one of them can be grounded.
