pressure or connected to power when electrically
connecting modules to the valve system.
O
Do not insert or disconnect plug connectors under load.
O
In order to assure both the protection class and the
required strain relief, the cable and plug assembly must
be done professionally and in accordance with the
assembly instructions.
Current flow in shield due to differences in potential
Compensating currents caused by differences in potential
must not flow over the shield of the PROFINET cable, as this
will cancel the shielding, which could damage the line and
connected participants.

If necessary, connect the grounding points for the system
using a separate line.
