Danger to life due to electric shock when touching live system components in
case of a ground fault
If a ground fault occurs, parts of the system may still be live. Touching live parts and cables
results in death or lethal injuries due to electric shock.
• Disconnect the product from voltage sources and make sure it cannot be reconnected
before working on the device.
• Touch the cables of the PV array on the insulation only.
• Do not touch any parts of the substructure or frame of the PV array.
• Do not connect PV strings with ground faults to the inverter.
Risk of burns due to hot enclosure parts
Some parts of the enclosure can get hot during operation.
• During operation, do not touch any parts other than the enclosure lid of the inverter.
Damage due to cleaning agents
The use of cleaning agents may cause damage to the product and its components.
• Clean the product and all its components only with a cloth moistened with clear water.
