6.2 Maintenance Schedule and Consumables
6.2.1 Notes on Maintenance Work
Adverse ambient conditions reduce maintenance intervals
Location and ambient conditions influence the maintenance intervals. Note that cleaning and corrosion protection
may be required more frequently depending on the conditions at the installation site.
• If the DC subdistribution is subject to adverse ambient conditions, it is recommended to shorten the
maintenance intervals.
• SMA recommends an optical inspection every six months to determine the maintenance requirements.
Maintenance report for maintenance
All maintenance work must be documented in a maintenance report. The maintenance report can be found in the
download area at www.SMA-Solar.com.
Consumables and maintenance materials
Only those consumables and maintenance materials not normally included in the standard equipment of an
electrically qualified person are listed. It is taken for granted that standard tools and materials such as torque
wrenches, one-contact voltage testers and wrenches will be available for all maintenance operations.
Spare parts
Only original parts or parts recommended by SMA Solar Technology AG are to be used as spare parts when
replacing components.
Spare parts can be identified via the reference designation and the circuit diagram. The spare-parts list includes
the article numbers of each spare part. For information on a specific article number, contact us (see Section9
"Contact", page68).
