8 Disconnecting the inverter from voltage sources
Prior to performing any work on the inverter, disconnect it from all voltage sources
as described in this section. Always adhere strictly to the prescribed sequence.
Procedure:
1.
Disconnect the AC circuit breaker and secure it against reconnection.
2.
Disconnect the DC switch and secure it against reconnection.
3.
Use a current clamp to ensure that no current is present in the DC cables.
4.
Release and remove all DC connectors. Insert a flat-blade screwdriver or an
angled screwdriver (blade width: 3.5 mm) into one of the slide slots and pull
the DC connectors out downwards. Do not pull on the cable.
5.
Ensure that no voltage is present at the DC input of the inverter using a suitable
measuring device.
6.
Loosen the screws of the cover using a screwdriver (T25) and remove the
cover.
Danger to life due to high voltages
The capacitors in the inverter take 5 minutes to discharge.
• Wait 5 minutes before opening the cover.
Destruction of the measuring device due to overvoltage
• Only use measuring devices with a DC input voltage range of 1000 V or
higher.
