5 Disconnecting the Inverter from Voltage Sources
15. Release and remove the DC connectors. To do so,
insert a flat-blade screwdriver or an angled
screwdriver (blade width: 3.5 mm) into one of the
side slots and pull the DC connectors out. When
doing so, do not lever the DC connectors out, but
insert the tool into one of the side slots only to
release the locking mechanism, and do not pull on
the cable.
16. Ensure that no voltage is present at the DC inputs of the inverter.
17. Disconnect the communication assembly from the
inverter. To do so, release and remove the ribbon
cable from the communication assembly.
18.
Danger to life due to high voltages in the inverter
The capacitors in the inverter take 20 minutes to discharge.
• Wait 20 minutes before opening the upper enclosure lid.
• Unscrew all screws of the upper enclosure lid (AF4) and remove the upper enclosure
lid.
19. Discharge the DC link in the following order. For this purpose use, for example, a 2-pole
voltage detector that does not have its own voltage source.
