12.2.1 Introduction
With IP54 protection degree, the container can be installed outdoors. Harsh environment condition
or long-time operation, however, may cause age and damage of the container. Check and maintain
the container periodically and replace the aged components can effectively enlarge the service life
and increase the device performance inside the container.
12.2.2 Maintenance Interval
Maintain the container and internal electric devices periodically to ensure the good performance of
the container.
The maintenance interval described in this chapter is indicative only. The actual interval depends
on the on-site environment condition. If the container is located in harsh environment places, for
example desert areas, the maintenance interval shall be shortened. Esp. the cleaning of the
container outside and anti-corrosion & anti-rust work should be more frequent.
If the container is located in desert areas, it is advisable to check thoroughly the container inside
and outside and clean completely after the sand storm.
WARNING:
Check the module fans inside the container periodically and the fans on top of the
cabinet for abnormal operation and abnormal noise. If so, there may be dust
penetrating inside the inverter. Stop the inverter and clean the dust.
Wait at least 5 minutes after the inverter discharge completely. Before cleaning, make
sure, with multimeter, the inverter internal is discharged completely to avoid electric
shock.
WARNING:
Almost all maintenance work needs to remove the internal protective grid during
maintenance. Make sure to reassembly the grid and fasten all the screws after the
maintenance work.
Make sure all bolts are securely fixed.
WARNING:
Once any unconformity is found during routine maintenance of the container and
internal devices please make correction immediately. If any doubts arise, please
contact CPS.
