5 Disconnecting the Inverter from Voltage Sources
5.1 With one-piece enclosure lid
Prior to performing any work on the inverter, always disconnect it from all voltage sources as
described in this section. Always adhere to the prescribed sequence.
Additionally required equipment:
☐ 2-pole voltage detector that does not have its own voltage source
Procedure:
1. Recommendation: Backup the event and log files using the inverter manager before the
replacement. This will prevent data loss.
2. Disconnect the AC miniature circuit breaker from all 3 line conductors and secure against
reconnection.
3. Set the DC load-break switch to position O and
secure against reconnection.
4. Disconnect the DC power supply in the distribution board (DC-Combiner).
5. 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.
6.
Danger to life due to high voltages
The capacitors in the inverter take 60 minutes to discharge.
• Wait 60 minutes before opening the enclosure lid.
7. Loosen the 2 fastenings screws on the clamping
frame above the display (TX20) and remove the
clamping frame.
8. Remove the display from the display opening.
