Excessive line capacitance can prevent the relay contacts from interrupting
the contact current. In control circuits operated with alternating current, take
into account the effect of the line capacitance of long control cables on the
function of the relay contacts.
If you want to route Ethernet connections from a control cabinet or building,
we recommend using fiber-optic cables (in accordance with the
IEC61850-90-4 recommendation).

6.4.2 Electromagnetic compatibility
The device has been developed in accordance with applicable EMC stan-
dards. The following points must be noted in order to maintain the EMC
standards.
6.4.2.1 Wiring requirement of installation site
Note the following when selecting the installation site:
▪ The system's overvoltage protection must be effective.
▪ The system's ground connection must comply with all technical regula-
tions.
