3. Insert the J2 end (use either end of the NKTM01 cable) of
the NKTU02 or NKTU12 cable into the MMU backplane slot
assigned to the master or slave module. The cable should latch
securely into place. Card edge connector P3 of the master or
slave module connects to this end of the cable.
4. Connect the shield wire extending from the J2 end of the
NKTU02 or NKTU12 cable to the shield bus bar.
5. Insert the J1 end (use the remaining end of the NKTM01
cable) of the NKTU01 or NKTU12 cable into the termination
mounting unit backplane slot assigned to the IDI module. The
cable should latch securely into place. Card edge connector P1
of the IDI module connects to this end of the cable.
6. Insert the master or slave module into the MMU until it
locks into place.
7. Replace or add the cable retaining bracket if round type
cables are installed in the termination mounting unit.
Installing the Termination Module
The IDI termination module inserts into a standard INFI 90 ter-
mination mounting unit and occupies one slot. To install:
NOTE: Insure all jumpers are configured prior to installation.
1. Verify the slot assignment of the IDI module.
2. Align the IDI module with the guide rails in the termination
mounting unit and partially insert the module.
Terminal Wiring
Field and power wiring must be connected to the IDI terminal
strip. See Figure
for IDI termination module terminal strip
assignments. Digital inputs must be connected to the IDI mod-
ule in one of two ways depending on how they are powered.
Fuse system powered digital inputs with at least one fuse per
IDI module. The fuse must be located between system power
and the field contacts. Figure
shows an example of system
powered digital input connections. Connect field powered digi-
tal inputs so that they switch the hot lead instead of the
ground or common lead. Figure
shows an example of field
powered digital input connections.
