9 Maintenance , Repair and Cleaning
Prior to removal of any cover for maintenance or repair, turn off
the switch on the AC and DC sides
9.1 Checking Heat Dissipation
If the inverter regularly reduces its output power due to high temperature,
please improve the heat dissipation condition. Maybe you need to clean the
heat sink.
9.2 Cleaning the Inverter
If the inverter is dirty, turn-off the AC breaker and DC switch ,waiting the
inverter shut down ,then clean the enclosure lid, the display, and the LEDs
using only a wet cloth. Do not use any cleaning agents (e.g. solvents or
abrasives).
9.3 Checking the DC Isolator
Check for externally visible damage and discoloration of the DC Isolator and
the cables at regular intervals.If there is any visible damage to the DC Isolator,
or visible discoloration or damage to the cables, contact the installer.
Once a year, turn the rotary switch of the DC Isolator from the On
position to the Off position 5 times in succession. This cleans the contacts
of the rotary switch and prolongs the electrical endurance of the DC
Isolator.
