5.3 Opening the Maintenance Compartment Door

Precautions

NO TICE

● Do not open the host panel cover of the inverter.
● Before opening the maintenance compartment door, ensure that no electrical

connections are made for the inverter on the AC or DC side.

● If you need to open the maintenance compartment door in rainy or snowy

days, take protective measures to prevent rain or snow entering the

maintenance compartment. If unavoidable, do not open the maintenance

compartment door.

● Do not leave unused screws in the maintenance compartment.

Procedure

Step 1 Partially loosen the two screws on the maintenance compartment door.

Step 2 Open the maintenance compartment door and install a support bar.

Figure 5-1 Opening the maintenance compartment door

Step 3 Remove the accessories that are bound in the maintenance compartment for

future use.

NO TE

For some models, a three-hole rubber plug is bound in the maintenance compartment.

After removing the rubber plug, save it properly for future use
