4.1 Safety during Commissioning
Danger to life from electric shock due to live voltage
High voltages are present in the live components of the product. Touching live components results in death or serious
injury due to electric shock.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch any live components.
• Observe all warning messages on the product and in the documentation.
• Observe all safety information of the module manufacturer.
• After switching off the inverter, wait at least 15 minutes before opening it to allow the capacitors to discharge
completely (see Section 5.2, page 51).
Danger to life from electric shock due to ground fault
If a ground fault has occurred, parts of the PV power plant that are supposedly grounded may in fact be live.
Touching incorrectly grounded parts of the PV power plant results in death or serious injuries from electric shock.
• Before working on the PV power plant, ensure that no ground fault is present.
• Wear suitable personal protective equipment for all work on the device.
