To ensure that the SUN2000 can operate properly for a long term, you are advised to perform
routine maintenance on it as described in this chapter.

Before cleaning the system, and maintaining the cable connections and grounding
reliability, power off the system (see 6.3 Powering Off the SUN2000) and ensure that the
two DC switches on the inverter are OFF.

If you need to open the maintenance compartment door in rainy or snowy days, take
protective measures to prevent rain and snow entering the maintenance compartment. If it
is impossible to take protective measures, do not open the maintenance compartment door
