CAUTION
ensuring reliable heat dissipation through the box is important.

CAUTION
x
While wiring the controller, disconnect the circuit breaker or fast-acting fuse
and ensure the electrode polarity is correctly connected.
x
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.
x
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.
CAUTION
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.
Step 4 ˖ ˖ Connect accessories
y Connect the remote temperature sensor cable (model: RTS300R47K3.81A)
Connect one end of the remote temperature sensor cable
to the interface
ʔ
and place the other end close to the battery.
CAUTION
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
without temperature compensation.
y Connect the accessories for RS485 communication
Refer to 3.2 “Setting and Operation of Controller.”
CAUTION
The RS485 port is designed without isolation, and it is recommended to connect
an RS485 communication isolator at the interface for communication.
