2.2 Safety Precautions
DANGER!
Danger to life due to high voltages in the Sunny Boy!
• All work on the Sunny Boy must be carried out exclusively by 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!
If the device has been temporarily decommissioned, proceed as follows to restore the IP65
protection rating:
• 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 Solar Technology recommends connecting and grounding the generator frame and
other electricity conducting surfaces in such a way that there is continuous conduction and
grounding in order to achieve maximum protection for systems and persons.
