11 Shutdown/Disassembly
11.1

Shutdown

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 may occur if the cables and terminals in the inverter are touched.
When there is solar radiation, DC voltage will be present at the open ends of the DC leads. Arcing may
occur if the DC cables are disconnected while they are still live.
›
It is essential that the shutdown sequence is 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 dis-
connect the DC main switch on the generator junction box at all poles (or the DC plug connectors).
Disconnecting the grid voltage is not enough.
CAUTION
Risk of burns from hot housing components.
The housing surface and the semiconductor can adopt a surface temperature of 75° in operation.
›
Do not touch the housing surface or semiconductor during and immediately after operation.
›
Allow the device to cool down before touching the housing surface.
Shutdown sequence
1. Switch off the grid voltage by turning off the external circuit breakers.
2. Disconnect the PV generator using the DC isolator switch.
DANGER! The DC cables are still live.
Ensure that there is no voltage present on the grid connection terminals.
11.2

Uninstallation

Shut down the inverter.
1. Open the connection area.
2. Remove the interface cable.
3. Detach DC connection plug.
4. Detach AC connection plug.
5. Unfasten cable ties.
6. Pull out the cables.
» The uninstallation of the inverter is complete. Continue with the disassembly.
