If the enclosure openings are not adequately sealed, renew the sealing material.
Adverse ambient conditions
Location and ambient conditions influence the maintenance intervals. In particular, cleaning and corrosion protection
work may be required more frequently depending on the conditions at the installation site.
• If the PV power plant is subject to adverse ambient conditions, it is recommended to shorten the maintenance
intervals.
