UPS MKD2000/3000 Manual
8.2 Communicational interface of the UPS
A convenient communications interface is available that facilitates data
exchange with the UPS.
The connection should only be made using the cables specified in the
“Accessories” chapter.
When using the SNMP adapter, the communicational interface is switched-off.

The communicational interface is completely galvanically isolated.
The UPS can also be forced to shut down immediately during support mode
via the RS232 serial interface. This is triggered via a permanent +12V signal
on receive data (Rx) (shutdown function).
