10 Disconnecting the Inverter from Voltage Sources

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.

Destruction of the measuring device due to overvoltage

• Only use measuring devices with a DC input voltage range of 1000 V or higher.

Procedure:

1. Disconnect the AC circuit breaker and secure it against reconnection.

2. Set the DC load-break switch of the inverter to

O

.

3. Wait until the LEDs have gone out.

4. Use a current clamp to ensure that no current is

present in the DC cables.
