Equipment and Front Access Cable Installation

Notes

:

1. Inputs to the minor alarm and power minor alarm connections are normally derived from

the -48 volt alarm outputs of a SLC

®

Series 5 Carrier System power shelf. An external

ground must be connected to output-common to access the alarm. Refer to Figure 3-8
(Releases 6 and 7) or Figure 3-10 (Releases 8, 9, 11 and 13).

2. The external inputs to the miscellaneous (environmental) discretes is a contact closure

and is connected to the DDM-2000 by two leads (wires). For each of the miscellaneous
(environmental) inputs that are being used, connect one lead to input-common (TLMI-C)
and the other lead to the appropriate alarm designation (TLMI-#). Refer to Figure 3-8
(Releases 6 and 7) or Figure 3-10 (Releases 8, 9, 11 and 13).

3. J262 and J261 refer to the cable connector at the end of the dangler.
