2 Safety
Danger to life due to electric shock when live components or DC cables are
touched
The DC cables connected to a battery or a PV module may be live. Touching live DC cables
results in death or serious injury due to electric shock.
• Disconnect the product and battery from voltage sources and make sure it cannot be
reconnected before working on the device.
• Wait five minutes before working on the inverter.
• Observe all safety information of the battery manufacturer.
• Do not touch non-insulated parts or cables.
• Do not pull the DC conductors under load out of the terminal blocks.
• Wear suitable personal protective equipment for all work on the product.
Danger to life due to electric shock from touching an ungrounded PV module
or array frame
Touching ungrounded PV modules or array frames results in death or lethal injuries due to electric
shock.
• Connect and ground the frame of the PV modules, the array frame and the electrically
conductive surfaces so that there is continuous conduction. Observe the applicable local
regulations.
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 and battery 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.
• Ensure that no voltage is present and wait 5 minutes before touching any parts of the PV
system or the product.
