50 V00 Installation and operating instructions
8 Disconnecting the Inverter from Voltage Sources
Before 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 against reconnection.
2.
Disconnect the DC-switch and secure against reconnection.
3.
Use a current clamp meter 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.
Loosen the screws of the lower cover using a screwdriver (T25) and remove
the 4 screws.
6.
Use a suitable measuring device to check that no voltage is present at the AC
screw terminal block between L and N, L and PE, then use a blade screw driver
(blade size: 1.0 x 5.5mm) to loosen the screws on the AC terminal block.
7.
Unscrew the screws of the terminal block and the swivel nut of the cable gland,
remove the AC cable.
8.
Tighten the swivel nut (SW46) of the cable gland and secure the 4 screws on
lower cover using a screwdriver (Type: T25, torque: 2.5 Nm).
Danger to life due to high voltages!
The capacitors in the inverter take 5 minutes to discharge.
• Wait 5 minutes before opening the cover.
