Align fixing holes of the controller with the two pre-fixed screws and hang
the controller up. And then fix the lower two screws.
Step 4: Wiring
For installation safety, we recommend a wiring sequence as follows;
however, wiring in other sequence instead of this one will not damage the
controller.
Warning: Danger, Electric shock hazards! We strongly recommend connect a
fuse or circuit breaker to the PV array and battery terminals to prevent electric shock
hazards during wiring or error operation, and make sure that fuse or circuit breaker is
disconnected before wiring.
Warning: Danger, High voltage hazards! Photovoltaic arrays may generate
very high open circuit voltages. Disconnect circuit breaker or fuse before wiring and be
