3.3.3 INCOM™ Network Communications
Note: To satsify IMPACC Wiring Specifications use only Belden 9463 OR 3072F, or
Culter-Hammer IMPCABLE shielded twisted pair cable or equivalent, according to
system requirements. SEE TD17513, IMPACC WIRING SPECIFICATIONS BASE
RULES for more detailed information.
Connect the IQ200 to the IMPACC network by connecting the twisted pair
communication cable to the INCOM™ port located on the rear face of the IQ 200
Base Module. The polarity of the twisted pair is not important.
Tie the communication cable shield to ground only once at the INCOM™ master
device. If there are more that one remote INCOM™ compatible devices (such as the
IQ 200) cabled to the master device, tie the communication cable shields together
but
do not connect to ground.
Care must be taken in stripping wire due to close proximity of terminals.
CAUTION
PREPARE THE CABLE FOR ATTACHMENT TO THE INCOM™ JACK TO AVOID
SHORTING CABLE SHEILD TO POWER INPUT TERMINALS.
Carefully strip the end of the communi-
cation wire as described in TD 17513.
Install the INCOM™ jack onto the
prepared cable. Place the cable and
jack assembly into the recess in the
side of the shroud component of the
supplied Phoenix Contact Cable
Housing that includes a supplied wire
tie as shown in figure 3.15. Ensure that
the supplied wire tie passes through
the holes in the shroud so the ends of
the tie flank the cable, as shown in
figure 3.15. Tighten the wire tie to
secure the cable to the shroud.

pulse trains are shown in figures 3.15 and 3.16. The energy represented by each
pulse can be specified by the user as: apparent (VAh) ; forward or reverse real
