2 Safety
Danger to life due to electric shock when live components or cables of the
inverter are touched
High voltages are present in the conductive components or cables of the inverter. Touching live
parts and cables of the inverter results in death or lethal injuries due to electric shock.
• Disconnect the inverter from voltage sources and make sure it cannot be reconnected
before working on the device.
• After disconnection, wait 5 minutes until the capacitors have discharged.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch non-insulated parts or cables.
Danger to life due to electric shock when live components or DC cables are
touched
When exposed to light, the PV modules generate high DC voltage which is present in the DC
cables. Touching live DC cables results in death or lethal injuries due to electric shock.
• Do not touch non-insulated parts or cables.
• Disconnect the inverter from voltage sources and make sure it cannot be reconnected
before working on the device.
• Do not disconnect the DC connectors under load.
• Wear suitable personal protective equipment for all work on the product.
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 inverter 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.
• Once disconnected from voltage sources, wait five minutes before touching any parts of the
PV system or the inverter.
