MOUNTING
WARNING
• Risk of explosion! Never install the controller in a sealed
enclose with flooded batteries! Do not install the controller 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 turn o the
breaker before wiring and be careful when wiring.
• Controllers have no battery reverse protection. Do not
reverse the battery during the wiring. Otherwise, the
controller may be damaged.
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 procedures:
Step 1: Determine the installation location and heat-dissipation space
When installing the controller, ensure enough air flowing through the
controller’s heat sink. Please leave at least 150mm clearance away from the
upper and lower edges.
CAUTION
Ventilation is highly recommended if mounted in an enclosure.
