2.2 Safety Precautions
DANGER!
Danger to life due to high voltages in the inverter
• All work on the inverter must be carried out by skilled persons only.
CAUTION!
Risk of burns due to hot enclosure parts
• Do not touch the enclosure body during operation.
• Only touch the enclosure lid during operation.
NOTICE!
Water- and dust intrusion can damage the inverter.
Once the Electronic Solar Switch has been pulled out, the inverter only provides protection
rating IP21. The inverter is thus no longer protected against water- and dust intrusion. In
order that the degree of protection IP65 is also maintained during temporary
decommissioning, proceed as follows:
• Release and disconnect all DC connectors.
• Open all DC connectors and remove the cables.
• Close all DC inputs using the corresponding DC connectors and the supplied sealing
plugs.
• Firmly re-connect the Electronic Solar Switch.
NOTICE!
Damage to the inverter due to moisture and dust intrusion
If the Electronic Solar Switch is not plugged in or incorrectly plugged in during operation,
moisture and dust can penetrate the inverter.
If the Electronic Solar Switch is not correctly plugged in, this can cause contacts to wear in
the Electronic Solar Switch or the Electronic Solar Switch might fall out. This can result in
yield loss and damage to the Electronic Solar Switch.
Always plug in the Electronic Solar Switch as described in the following:
• Do not tighten the screw in the Electronic Solar Switch.
• Firmly plug in the Electronic Solar Switch until it is flush with the enclosure.
• Ensure that the maximum distance between the Electronic Solar Switch and the
enclosure is 1 mm.
