Connecting the Cable for Remote Shutdown

The remote shutdown enables the inverter to be switched off from a distance, e.g. from a control room. The function of
the remote shutdown is similar to the stop function of the key switch.
Shortfall of external supply voltage
If there is an external supply voltage between 18.5 V to 24.0 V, the inverter will continue to operate in its current
operating state. If the external supply voltage falls below 18.5 V, the inverter switches from the current operating
state to the operating state "Stop". If the temperature inside the inverter exceeds the temperature limit, a supply
voltage of 20.0 V to 24.0 V must be present to continue operating the inverter in its current operating state.
Temperature limit: +60°C
• Ensure that the external supply voltage is between 20.0 V and 24.0 V.
Procedure:
1. Disassemble the panels (see Section 7.2.1, page 41).
2. Insert the cables (see Section 7.1, page 41).
3. Connect the cables in accordance with the circuit diagram (see Section 7.4, page 50).
4. Secure the cables on the cable support rail. This will prevent the cables from being pulled out inadvertently.
5. Mount the panels (see Section 7.2.1, page 41).

Connecting the Cable for the Status Report of the Insulation Monitoring

Status report
The switching status can be queried via a contact. For details of terminal assignment, see circuit diagram.
Requirements:
☐ The connected load must operate with a voltage of 230 V
☐ The connected load must draw a current of 10 mA to 6 A.
Procedure:
1. Disassemble the panels (see Section 7.2.1, page 41).
2. Insert the cables (see Section 7.1, page 41).
3. Connect the cables in accordance with the circuit diagram (see Section 7.4, page 50).
4. Secure the cables on the cable support rail. This will prevent the cables from being pulled out inadvertently.
5. Mount the panels (see Section 7.2.1, page 41).
5.6.8

Connecting the Cable for the Supply Voltage

The inverter must be connected to an external, three-phase supply voltage with 230 V line voltage/400 V line-to-line
voltage (3/N/PE) per line conductor.
Circuit breaker between the external supply voltage and the inverter
A type-B circuit breaker with a rated current of 16 A is installed in the inverter.
• Provide a selective circuit breaker for insulating the cable to the inverter.
Cable requirements:
☐ The cable used must be shielded.
☐ Maximum conductor cross-section: 10 mm
