10 Decommissioning
10�1 Instructions for inverter replacement
When replacing the inverter, note the following:
 Before replacing the inverter, write down the total yield. The procedure for viewing
the total yield is described in Section 7.5.4.
10�2 Dismounting the inverter
The inverter may only be dismounted by qualied electricians.
DANGER!
Fatal electric shock hazard!
Components within the inverter are charged with a high voltage. After the
inverter has been disconnected, high residual voltages remain in the inverter
for approx. 5 minutes.
 Before starting to dismount the inverter, the inverter must be fully discon-
nected in accordance with the procedure described in this chapter.
WARNING!
Risk of injury from electric arc!
Dangerous electric arcs could occur when removing live DC input conductors.
 Switch off the DC disconnector before removing the DC input
conductors.
Procedure
1. Disconnect the AC power supply to the inverter (switch off the external AC circuit
breaker).
– The "No grid" status message is shown on the inverter.
2. Switch off the DC disconnector at the inverter.
