11 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.

WARNING

Danger to life due to electric shock from destruction of the measuring device
due to overvoltage

Overvoltage can damage a measuring device and result in voltage being present in the
enclosure of the measuring device. Touching the live enclosure of the measuring device results in
death or lethal injuries due to electric shock.

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

Procedure:

1. Disconnect the circuit breaker from all three line conductors and secure against reconnection.
2. If the multifunction relay is used, switch off any supply voltage to the load.
3. Turn the DC load-break switch to the position

O

.

4. Wait until the LEDs have gone out and, if necessary, the load connected to the multifunction

relay has been switched off.

5. Use a current clamp to ensure that no current is present in the DC cables.
6. Unscrew the two screws on the DC load-break

switch using an Allen key (AF 3).
