Connecting communication
GUID-ABE5A9D7-4292-4AE3-A8B7-0C52F54E754E v7
Before connecting communication, check that the HW module has the correct communication
interfaces. The communication module is located on the left side of the IED when viewing the
case from the rear.
The fiber optical cables are very sensitive to handling. Do not bend too sharply. The minimum
curvature radius is 250 mm for the glass fiber cables. If cable straps are used to fix the cables,
apply with loose fit.
Always hold the connector, never the cable, when connecting or disconnecting optical fibers.
Do not twist, pull or bend the fiber. Invisible damage may increase fiber attenuation thus
making communication impossible. Strictly follow the instructions from the manufacturer for
each type of optical cables/connectors.
See the technical manual for product-specific communication interfaces.
