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).
