Period

Cable entry

Check whether the cable entry is in-

sufficiently sealed or the gap is exces-

sively large, and reseal the entry

when necessary.

Once a year

Electrical

Connection

Check whether all cable are firmly

connected in place.

Check whether a cable is damaged,

especially the part contacting the met-

al enclosure.

Six months to a year

9.2.3 Cleaning Air Inlet and Outlet

A significant amount of heat is generated when the inverter is working.

In order to maintain good ventilation, please check to make sure the air inlet and outlet are

not blocked.

Clean the air inlet and outlet with soft brush or vacuum cleaner if necessary.

9.2.4 Fan Maintenance

•

Power off the inverter and disconnect it from all power supplies before main-
taining fans.

•

After the inverter is powered off for 15 minutes, measure the voltage and cur-
rent with professional instrument. Only when there is no voltage nor current
can operators who wear protective equipment operate and maintain the inverter.

•

Fan maintenance must be performed by professionals.

Fans inside the inverter are used to cool the inverter during operation. If the fans do not op-

erate normally, the inverter may not be cooled down and inverter efficiency may decrease.

Therefore, it is necessary to clean dirty fans and replace the broken fans in a timeiy manner.

The operation procedure is as follows:

step 1 Stop the inverter

（

8.1 Disconnecting the Inverter

）

step 2 Loosen the screw on the sealing plate of the fan module.

step 3 Press the tab of the latch hook, unplug the cable connection joint outwards, and loosen the

screw on the fan holder.
