2. Mount the Marshalling Utility Panel, Utility Panel or user fabricated panel in a MODULPAC
marshalling cabinet or user supplied cabinet. Refer to Instruction SD39MODULPAC-1 for
installation of the Utility Panel or Marshalling Utility Panel.
3. Retrieve the EAM Marshalled Termination Assembly to be mounted including a supplied bag of
EAM labels (PN 14205-665) and a Cable Keying Kit (PN 16056-435). Set aside the Cable Keying
Kit.
1) Consult user documentation and note the MODULRAC address number (1 to 16) and slot number
(1 to 10) assigned to the EAM, and if applicable the redundant EAM that will be connected to this
EAM Marshalled Termination Assembly. For rack-to-rack redundant EAMs connected to a
MODULNET, the MODULNET node address must also be noted for each MODULRAC.
2) Retrieve an EAM label and record the noted MODULRAC and slot numbers on the label (see
Figure 1-1) If MODULNET redundancy is applicable, record the appropriate node addresses on
both EAM labels. Save the remaining labels for use in section 2.6.3.
4. Refer to Figure 1-1 and attach the EAM label adjacent to connector J1 as illustrated in the figure. If
applicable, attach the redundant EAM label adjacent to J2. Ensure that J1 and J2 are factory keyed
according to the pattern shown in Figure 2-3.
The user then keys the connector on the mating
Interconnect I/O Cable, in section 2.6.3. This prevents connection to the Termination Assembly
of an Interconnect I/O Cable from another type of APACS I/O module (e.g. SDM or VIM).
5. Refer to Figure 2-5 to mount the EAM Marshalled Termination Assembly to a DIN rail.
2.6.2 Optional (Flat Surface) Marshalled Termination Assembly Installation
The removal of the DIN rail mounting feet from the EAM Marshalled Termination Assembly (MTA), in
conjunction with the installation of four Mounting Ears (accessory item), permits the MTA to be flat
mounted to a panel or bulkhead. Four P/N 16056-562 (single piece) Mounting Ears are required per
MTA.
Refer to Figure 2-6 and the following installation procedure:
1. At one end of the MTA, remove the three end cap securing screws from the card holder End Cap.
Remove and set aside the End Cap.
2. Slide the DIN rail mounting feet from the grooves in the bottom of the MTA card holder. Discard the
mounting feet and re-install the just removed End Cap.
3. Retrieve four Mounting Ears and insert them in the appropriate mounting holes provided in the End
Caps as illustrated in Figure 2-6.
4. Use the MTA as a template to mark the location of the mounting ear holes on the surface of the panel.
Refer to Figure 2-3 for MTA dimensions.
5. Typical mounting screw size is M4, or users can select another size. After drilling or punching the
holes, the holes should be threaded.
