7 Disconnecting from Voltage Sources
2. Disconnect the DC power supply in the
distribution board (DC-Combiner).
3. Use a current clamp to ensure that no current is
present in the DC cables. Information:
Depending on the model, several positive and
negative pole lines are connected to the inverter.
Always ensure that there is no current on all DC
lines.
4. Wait 60 minutes before opening the enclosure
lid.
5. Set the DC load-break switch to O and secure
against reconnection.
6. Open the installation area ((see Section 5.6,
page 25)).
7. Use an appropriate measuring device to ensure
that no voltage is present at the AC terminal
block between L1 and PE, L2 and PE, L3 and
PE, L1 and L2, L2 and L3 and L1 and L3.
8. Ensure that no voltage is present at the DC inputs
of the inverter using a suitable measuring device.
