It may be necessary to reverse the module
mounting in the lower row of the MLE-6
enclosure to insure that the 14-conductor
cables that are supplied can be assembled
(See Figure 5).
5. Note that there are two eight conductor
cables. The long eight conductor cable
(P/N 555-192243) comes with the ACM-1.
Use this cable for communications and
power from P4 on the OMM-1 to either P6
on the PSR or to P6 on the MMB,
whichever is present.
This cable is polarized. Observe polarity
and DO NOT USE EXCESSIVE FORCE.
The black tracer on the cable indicates
the position of pin 1.
6. If there is more than one OMM-1, use the
short eight conductor cable (P/N 555-
190967) to connect P3 of the left-hand
OMM-1 to P4 of the OMM-1 that is to its
right.
This cable is polarized. Observe polarity
and DO NOT USE EXCESSIVE FORCE.
The black tracer on the cable indicates
the location of pin 1. If there are more
OMM-1s in the system, repeat this step.
For additional information on the
MXLV System, refer to the MXLV
Manual, P/N 315-092036.
CAUTION
Handle all plug-in cards with extreme care.
When inserting or removing a card, keep
the position of the card at right angles to
the OMM-1 board. Otherwise, the plug-in
card can damage or displace other com-
ponents. Never insert or remove a plug-in
card with power applied to the panel.
WIRING
(Refer to Figures 4 and 5)
All wiring must comply with
national and local codes.
1. When the 24 VDC is provided by either
the MMB-2/-3 or SMB-2 or PSR-1, use
TB1 on the OMM-1 to connect the power.
The wire for this connection is not
supplied (See MMB-2 Installation
Instructions, P/N 315-095097, or MMB-3
Installation Instructions, P/N 315-048860,
or SMB-2 Installation Instructions, P/N
315-095931, or PSR-1 Installation
Instructions, P/N 315-090911, for terminal
connections.)
2. Assign plug-in cards to the card edge
connectors as determined above. Once
the terminal block related to each edge
connector is wired, place only the
assigned plug-in card in that edge
connector.
3. Refer to the Installation Instructions listed
in Table 1 for directions on wiring to the
22 position OMM-1 terminal blocks and
for attaching these modules to the OMM-1
terminal blocks.
4. If the system includes more than one
OMM-1, use the fourteen conductor
ribbon cable (P/N 555-192155) to connect
P1 of the first OMM-1 to P2 of the second
OMM-1. If there is a third OMM-1,
connect P1 of the second OMM-1 to P2 of
the third OMM-1. No more than three
OMM-1s can be connected together when
they are installed in an MME-3 enclosure.
