6.6.1 Cable recommendation
Please note the following Maschinenfabrik Reinhausen GmbH recommenda-
tion when wiring the device.
▪ Excessive line capacitance can prevent the relay contacts from interrupt-
ing 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 build-
ing, we recommend using fiber-optic cables (in accordance with the
IEC 61850-90-4 recommendation).
▪ Ensure that the copper cables used have a temperature resistance of
70°C.
