CAUTION ensuring reliable heat dissipation through the box is important.
Step 2 Connect the system in the order of
2-2," Schematic Wiring Diagram" and disconnect the system in the reverse order
While wiring the controller, disconnect the circuit breaker or fast-acting fuse
and ensure the electrode polarity is correctly connected.
A fast-acting fuse whose 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.
CAUTION
Suppose an inverter is to be connected to the system. In that case, you must
connect the inverter directly to the battery, not to the load side of the
controller.
Step 3 Grounding
As the TRIRON series is a common negative controller, the negative poles of the PV array, battery
and load can be grounded together.
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
CAUTION
only one of them can be grounded.
Step 4 Connect accessories
Connect the remote temperature sensor cable (model: RTS300R47K3.81A)
Connect one end of the remote temperature sensor cable
to the interface and place the other end close to the battery.
Suppose the remote temperature sensor is not connected to the controller. In
that case, the default battery charging or discharging temperature setting is 25°C
CAUTION
without temperature compensation.
Connect the accessories for RS485 communication
Refer to 3.2 "Setting and Operation of Controller."
The RS485 port is designed without isolation, and it is recommended to connect
an RS485 communication isolator at the interface for communication.
