Cable Connections Section 2-4
Also be sure to cover the unused connectors on the highest and lowest nodes
in the network with the provided Optical Connector Covers.
Note (1) Always use the specified Optical Fiber Cables.
(2) The maximum distance between nodes depends on the method used to
attach the connector to the cable.
Installing Connectors
A special connector is used to connect the Optical Fiber Cable to the SYS-
MAC LINK Unit.
This manual does not provide details on Optical Fiber Cable preparation.
Observe the following precautions when connecting the Optical Fiber Cables.
• Always turn OFF the PLC power supply before connecting Optical Fiber
Cables.
• Special tools are required to attach Optical Fiber Cables to the connec-
tors. The cable may disconnect from the connector if the proper tools and
methods are not used during cable assembly.
• Insert the connectors completely and always check that the connectors
are locked before starting operation.
• If a connector becomes disconnected, the node will be unable to commu-
nicate with other nodes in that part of the network. The network will be
divided into two and communications with the remaining nodes will be
unreliable. Be sure not to remove connectors during communications.
• Do not pull on the Optical Fiber Cable too forcefully.
The maximum tension that can be applied to the cord is 10 kg and the
maximum tension that can be applied to the cable is 50 kg.
• Do not bend the cable too sharply. The minimum radius for bends is
10 cm.
