Safety Precautions - SMA SUNNY MINI CENTRAL 4600A Installation Manual

Safety
2.2 Safety Precautions
DANGER!
Danger to life due to high voltages in the inverter.
• All work on the inverter may only be carried out by an electrically qualified person.
CAUTION!
Risk of burns due to hot enclosure parts.
• Do not touch the enclosure during operation.
• Only touch the enclosure lid during operation.
NOTICE!
Dust and water intrusion can damage the inverter.
Once the Electronic Solar Switch has been pulled out, the inverter only provides degree of
protection IP21. The inverter is then no longer protected against water and dust intrusion.
In order to also maintain degree of protection IP65 during temporary decommissioning,
proceed as follows:
• Unlock and disconnect all DC connectors.
• Open all DC connectors and remove the cables.
• Close all DC inputs with the corresponding DC connectors and the supplied sealing
plugs.
• Firmly connect the Electronic Solar Switch again.
PV array grounding
Comply with the local regulations for grounding the PV modules and the PV array. In order
to maintain the best possible protection for both the PV plant and human life,
SMA Solar Technology AG recommends connecting together the PV array frame and other
electrically conductive surfaces and grounding them.
