Allen-Bradley SLC 500 Installation And Operation Manual

A–16 Setting Up the DH-485 Network
Publication 1747-6.2
You can connect an unpowered link coupler to the DH-485 network
without disrupting network activity. In addition, if an SLC 500
controller powers a link coupler that is connected to the DH-485
network, network activity will not be disrupted should the SLC 500
controller be removed from the link coupler.
Installing and Attaching the Link Couplers
1. Take care when installing the link coupler in an enclosure so that
the cable connecting the SLC 500 controller to the link coupler
does not hit the enclosure door.
2. Carefully plug the terminal block into the DH-485 port on the
link coupler you are putting on the network. Allow enough cable
slack to prevent stress on the plug.
3. Provide strain relief for the Belden #9842 cable after it is wired to
the terminal block. This guards against breakage of the Belden
cable wires.
