DANGER
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
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.
• Only touch the cables of the PV modules on their insulation.
• 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.
DANGER
Danger to life due to electric shock when live components are touched on
opening the inverter
High voltages are present in the live parts and cables inside the inverter during operation.
Touching live parts and cables results in death or lethal injuries due to electric shock.
• Do not open the inverter during operation.
• 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.
