CAUTION: The wire size is only for reference. If there is a long distance between the PV array
and the controller or between the controller and the battery, larger wires can be used to
reduce the voltage drop and improve performance.
CAUTION: For the battery, the recommended wire will be selected according to the
conditions that its terminals are not connected to any additional inverter.

Mounting
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.
WARNING: Risk of electric shock! When wiring the solar modules, the PV array can produce
a high open circuit voltage, so turn off the breaker before wiring and be careful when wiring.
CAUTION：
The controller requires at least 150mm of clearance aboveand below for proper
air flow. Ventilation is highly recommended if mounted in an enclosure.
Installation Procedure:
Figure 2-1 Mounting
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
throughthe 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 seeFigure 2-1: Mounting
