2.2 Safety Instructions
DANGER!
Danger to life due to high voltages.
• All work on the Sunny Boy must only be carried out by a qualified personnel.
CAUTION!
Danger of burn injuries due to hot housing parts!
• Do not touch the housing of the Sunny Boy during operation.
NOTICE!
Foreign objects or water entering the Sunny Boy can damage the device!
Once the Electronic Solar Switch has been pulled out, the Sunny Boy only provides
protection degree IP21. The Sunny Boy is then no longer protected against water and
contamination with dirt!
In order that the protection level IP65 is also provided during a temporary
decommissioning, proceed as follows:
• Unplug all DC plug connectors and seal them with the protecting caps provided.
• Attach the Electronic Solar Switch again.
Grounding the PV generator
Comply with the local requirements for grounding the modules and the PV generator. SMA
reccomends to electrically bond the module frames, the racks and all metal surfaces and
ground these in order to have optimal protection of the system and personnel.
