Connecting communication

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. 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.
