5.3 Maintenance

The following inspections and maintenance tasks are recommended at least two times per year for best performance.
 Check that the air flow and ventilation around the controller is not blocked. Clear all dirt or fragments on the heat sink.
 Check all the naked wires to make sure insulation is not damaged for serious solarization, frictional wear, dryness, insects or rats etc. Maintain or
replace the wires if necessary.
 Check and confirm that LED or LCD is consistent with required. Pay attention to any troubleshooting or error indication .Take corrective action if
necessary.
 Tighten all the terminals. Inspect for loose, broken, or burnt wire connections.
 Confirm that all the terminals have no corrosion, insulation damaged, high temperature or burnt/discolored sign, tighten terminal screws to the
suggested torque.
 Inspect for dirt, insects and corrosion, and clear up.
 Check and confirm that lightning arrester is in good condition. Replace a new one in time to avoid damaging of the controller and even other
equipments.
NOTE: Dangerous with electric shock!
Make sure that all power source of controller is cut off when operate above processes, make inspection or other operations！
