5.5 Serial interfaces for communication with PLCs or devices
The RS232- interface is not electrically isolated.
CAUTION
NON-GALVANICALLY-ISOLATED INTERFACES
The XV300 may be damaged by potential differences.
The GND terminals of all bus modules must be connected.
Do not connect the connector to the XV300 or disconnect it without
first de-energizing the system.
