Safety with insulation monitoring with GFDI and insulation monitoring device

Danger to life from electric shock due to live voltage
High voltages are present in the conductive components of the inverter. Touching live components results in death or
serious injury due to electric shock.
• After switching off the inverter, wait at least 15 minutes before opening it to allow the capacitors to discharge
completely.
• Wear suitable personal protective equipment for all work on the product.
• All work must be carried out in accordance with this document. All safety information must be observed.
• Do not touch any live components of the inverter or the medium-voltage grid. Comply with all applicable safety
regulations for handling medium-voltage grids.
Ground-fault monitoring with GFDI does not provide protection from personal injury.
