Danger to life due to fire or explosion
In rare cases, an explosive gas mixture can be generated inside the product under fault
conditions. In this state, switching operations can cause a fire inside the product or
explosion. Death or lethal injuries due to hot or flying debris can result.
• In the event of a fault, do not perform any direct actions on the product.
• Ensure that unauthorized persons have no access to the product.
• Only perform work on the product (e.g., troubleshooting, repair work) when wearing
personal protective equipment for handling of hazardous substances (e.g., safety
gloves, eye and face protection, respiratory protection).
• Wait at least 10 minutes for the internal capacitors to discharge after the battery is
powered off.
• Ensure that there is no voltage or current before installing or disconnecting any
connectors.
• All safety instructions, warning labels, and nameplate on the inverter should not be
removed or covered.
• Do not touch any hot parts (such as the heat sink) during operation. Only the DC
switch can safely be touched at any time.
Danger to life from electric shock due to live DC cables at the battery.
The DC cables connected to a battery may be live. Touching the DC conductors or the
live components leads to lethal electric shocks.
• Do not touch non-insulated cable ends.
• Do not touch any live components.
• Have the inverter and the battery mounted, installed and commissioned only by
qualified persons with the appropriate skills.
• Observe all safety information of the battery manufacturer.
• Prior to performing any work on the inverter or the battery, disconnect the inverter
from all voltage sources as described in this document.
• If an error occurs, have it rectified by qualified persons only.
