The recommended battery wire is selected when the battery terminals are not
connected to any additional inverter.

WARNING
Risk of explosion! Never install the controller in a sealed enclose with
flooded batteries! Do not install in a confined area where battery gas can
accumulate.
Risk of electric shock! When wiring the solar modules, the PV array can
produce a high open-circuit voltage, so disconnect the breaker before
wiring and be careful.
CAUTION
The controller requires at least 150mm of clearance above and below for
proper airflow. Ventilation is highly recommended if mounted in an enclosure.
Installation Procedure:
Figure 2-1 Mounting
Step 1: Determination of the installation location and heat-dissipation space
The controller shall be installed in a place with sufficient airflow through the controller radiators and
a minimum clearance of 150 mm from the upper and lower edges of the controller to ensure natural
thermal convection. See Figure 2-1: Mounting
CAUTION
Suppose the controller is to be installed in an enclosed box. In that case,
ensuring reliable heat dissipation through the box is important.
