7.Start-Up and shut down the inverter
7.1 Start-Up the inverter
1. Connect the AC breaker of the inverter.
2. Turn on the dc switch, and the inverter will start automatically when the input voltage is
higher than 200V.
7.2 Turn-off the Inverter
Do not disconnect the DC connectors under load.
Turn –off the inverter step:
1. Disconect the line circuit breaker from three-phases grid and prevent it from being
reactivated.
2. Turn off the dc switch.
3. Check the inverter operating status.
4. Waiting until LED, display have go out, the inverter is shut down.
8.Maintenance and Cleaning
8.1 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.
8.2 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).
8.3 Checking the DC Disconnect
Check for externally visible damage and discoloration of the DC Disconnect and the cables at
regular intervals. If there is any visible damage to the DC Disconnect, or visible discoloration
or damage to the cables, contact the installer.
Once a year, turn the rotary switch of the DC Disconnect 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 Disconnect.
