6.3 Connecting the bus coupler electrically

Applied electric voltage
Danger of injury from electric shock
Make sure the relevant system component is not under voltage or pressure
before electrically connecting modules to the valve terminal.
Faulty wiring
Faulty wiring can lead to malfunctions as well as damage to the network.
Unless otherwise stipulated, comply with the directive Network Infrastructure
for EtherNet/IP™ Publication Number: PUB00035R0.
Only a cable that meets the fieldbus specifications as well as the connection speed
and length requirements should be used.
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 bus cable, as this will remove the shielding, which could damage the
line and connected bus coupler.
If necessary, connect the measuring points for the system using
a separate line.
