Communication and Telephone Cable Wiring
A communication cable must join the EMU and the monitor. First you must verify
that the EMU cable connector is not connected to the monitor because cables easily
short and blow a fuse in the monitor when they are pulled through conduit.
Note:
The instructions on the seal-off data sheet (included with the seal-off
fitting) must be followed exactly to maintain a Class I, Division 1, Groups C
and D rating for installation.
Next, connect the individually colored-coded wires on the communication cable to the
hard-wired in-field connectors on the communications box inside the EMU (see the
following figure). The color wires should be installed in the following order to match
the marking strip alongside the hard-wired connectors. As you review the following
table, please note that 18 gauge wire is thicker than 22 gauge wire.
