Load disconnectors /D11 and /M11
WARNING
Electric shock due to dangerous voltages at the line terminals.
The switch disconnector disconnects the electronics cover from the voltage supply. Voltage is still present at the terminals of the device.
- A correct installation includes that terminals of the device are protected against contact.
- Secure the device against unintended reconnection of the voltage supply.
- Wait for at least the following time before removing the electronics cover: 5 minutes
NOTICE
Premature aging of the switch contacts.
- Do not operate the switch disconnector under load.
The switch disconnector of the device serves to interrupt the voltage supply of the electronics cover. The control unit of the decentralized inverter will remain supplied after the load disconnector is opened only if the optional, external DC 24 V backup voltage is connected.
The feedback contact (NC contact) of the switch disconnector affects the digital input DI04. You can query the load disconnector status at the digital input DI04 when the DC 24 V backup voltage is connected to the device.
INFORMATION
The M11 load disconnector remains in the "TRIP" position after an overcurrent trip.
To switch the device on again, set the switching position to "0". Only then can the power be switched on again.
The load disconnector can be secured with 3 locks.
