Directions to Wire Network
Network wiring consists of two pairs of twisted pair cable plus a communications
common wire. Category 5 ethernet cable is recommended. Network wires are
terminated at location D on I/O board - figure 3.25.
WARNING: Disconnect external power to the unit before wiring.
AVERTISSEMENT : déconnectez l’alimentation externe de l’unité avant
d’effectuer un câblage quelconque.
1. Perform steps 1 - 4 of 5200A installation and steps 5 and 6 as required
for the application.
2. Open front panel -page 39.
3. Strip five wires to terminate at network termination strip. Use appropriate
wire stripper to avoid wire nicks.
4. Feed networking cable through drilled hole in rubber grommet and to
location D. Terminal strip is removable.
Installation and Wiring
Note:
- It is essential that wires be terminated cleanly. Nicks (stray wires, not
cleanly terminated) can result in unreliable network communication.
CAUTION : Run high and low voltage wires/cables through separate bulk-
head and conduit.
