Specifications and Configurations Section 1-2

Note Normally, the communications cable must be disconnected from a Wired Con- troller Link Unit to replace it. Doing this, however, will interrupt communica- tions on the network, requiring that all node be turned OFF to ensure safety before replacing a Unit. With the above Relay Terminal Block, a Controller Link Unit can be replaced by turning OFF only the specific Unit being replaced, i.e., without turning OFF any other Units. The communications cables are left connected to the Relay Terminal Block and only the Relay Ter- minal Block is removed from the Controller Link Unit. (The built-in terminating

resistance connected at the Units at the end of the network prevents using the Relay Terminal Block on the end Units.) Refer to Appendix C Using the Relay Terminal Block for details on using the Terminal Relay Block.
