Risk of burns from touching hot components
The components of the DC sub-distributions and the central inverter can get very hot. Touching these
components may cause burns.
• Do not touch hot components.
• Wait until hot components have cooled down sufficiently.
• Observe all safety warnings in the DC sub-distributions and the inverter.
• Wear safety gloves when working on the device.
