2. Connect the assembled DC connectors to the
inverter.

☑ The DC connectors snap into place.
3. Ensure that all DC connectors are securely in place.
6.5.3
Disassembling the DC Connectors
To disassemble the DC connectors (e.g. due to faulty assembly), proceed as follows.
DANGER
Danger to life due to electric shock and electric arc when pulling off the DC
connectors when connecting a PV field to the battery inverter
If the DC connectors with the DC conductors of the PV field were accidentally connected to the
battery inverter, the high voltages of the PV field are present at the DC conductors. The removal
of the DC connectors results in death or serious injury due to electric shock and electric arc.
• Leave the DC connectors plugged on the battery inverter.
• Stop working on the inverter, and only once it is dark, unlock and then remove the DC
connectors and assemble again.
• If you would like to leave the system before troubleshooting, secure the danger zone
against unauthorized entry (e.g. with a fence).
DANGER
Danger to life due to electric shock when touching exposed DC conductors or
DC plug contacts if the DC connectors are damaged or loose
The DC connectors can break or become damaged, become free of the DC cables, or no longer
be connected correctly if the DC connectors are released and disconnected incorrectly. This can
result in the DC conductors or DC plug contacts being exposed. Touching live DC conductors or
DC plug connectors will result in death or serious injury due to electric shock.
• Wear insulated gloves and use insulated tools when working on the DC connectors.
• Ensure that the DC connectors are in perfect condition and that none of the DC conductors
or DC plug contacts are exposed.
• Carefully release and remove the DC connectors as described in the following.
