Shutdown/Disassembly

11.1

Switching off the unit

DANGER
Lethal voltages are still present in the terminals and cables of the inverter even after the
inverter has been switched off and disconnected.
Severe injuries or death will occur when touching the cables and terminals in the inverter.
When there is solar radiation, DC voltage will be present at the open ends of the DC cables. Arcing
may occur if the DC cables are disconnected while they are still live.
›
It is absolutely essential that the shutdown sequence be carried out in the correct order.
›
After shutdown, wait at least 30 minutes before working on the inverter.
›
When working on photovoltaic modules, in addition to disconnecting from the grid, always discon-
nect the DC main switch on the generator junction box at all poles (or the DC plug connectors).
Simply disconnecting the grid voltage is not sufficient!
CAUTION
Risk of burns from hot housing components.
The housing surface and the heat sink can adopt a surface temperature of 75° in operation.
›
Do not touch the housing surface or heat sink during and immediately after operation.
›
Allow the device to cool down before touching the housing surface.
