Decommissioning
13.1 Dismantling the Inverter
13.2 Packing the Inverter
1. Disconnect the inverter as described in section8.
2. Remove all connection cables from the inverter.
3. Screw off all projecting cable glands.
4. Lift the inverter off the bracket and unscrew the bracket screws.
CAUTION
Danger of burn injuries due to hot enclosure parts!
Wait 20 minutes before disassembling until the housing has cooled down.
If possible, always pack the inverter in its original carton and secure it with tension belts.
If it is no longer available, you can also use an equivalent carton. The box must be
capable of being closed completely and made to support both the weight and the size of
the inverter.
13.3 Storing the Inverter
Store the inverter in a dry place where ambient temperatures are always between -25°C
and +60°C.
13.4 Disposing of the Inverter
Do not dispose of faulty inverters or accessories together with household
waste. Please accordance with the disposal regulations for electronic waste
which apply at the installation site at that time. Ensure that the old unit and,
where applicable, any accessories are disposed of in a proper manner.
