ground source other than the system single
point ground described in (a) above.
(c) AC service wires bringing AC power to the
cabinet shall not share an enclosure or
raceway with any other system grounds,
DC power distribution wires. or signalling
wires All non-connectorired AC power
terminations shall be enclosed by raceways
and termination boxes whether these en-
closures appear outside or within the
system cabinet This is to ensure that AC
service wires cannot fault to circuitry
within the system or associated ducting
hardware.
(d) All system hardware shall be provided with
an AC fault return path to the system single
point ground, which in turn shall be pro-
vided with a reliable path to the equipment
grounding conductor (i.e. green wire
ground or safety ground). The path from
system equipment to system single point
ground need not be a direct dedicated
path, but can be any reliable path to other
system hardware which receives the above
grounding path
(e)' All sources of external ground he. system
signalling ground to the approved ground
source, etc.). shall connect only to the
system single point ground The intent of
providing for a system single point ground
is to minimize ground loops and prevent
lightning from finding a path through
system components
5. CABLING AND CROSS-CONNECTIONS
General
5.01 This part details the cabling and cross-
connections required when installing the
SX-5 Communications System
Telephone Set and Trunk Cabling
Note:
At present, only a 2-wire connection
per extension is required, however,
4-wire cables should be run to allow
for future expansion to features.
Cross-Connections
5.03 The extensions connected to Equipment
Numbers 1 and 2 have direct access to
trunks 1 and 2 respectively in the event of
Power Failure (refer to MlTL9103-
098- 1 00-NA, paragraph 3.06). For this reason.
consideration should be given to the type of
telephone that is to be connected to Equipment
Numbers 1 and 2; e.g if Trunk 1 is a ground start
trunk, the telephone connected to Equipment
Number 1 must have a ground button
5.04 Connection between the equipment cabinet,
stations. and trunks should be made using
26 AWG 2-pair cable.
5.05 Cabling connections to the SX-5 terminal
strip are shown in Fig. 003-1,
MAP200-003, Appendix 2.
6. INSTALLATION
General
6.01 Installation of the SX-5 consists of six
steps as detailed in Table 6- 1.
Synopsis
6.02 The following paragraphs contain a syn-
opsis for each of the MAP's included in
Appendix 2, Installation Procedures These out-
lines may be used by the experienced installer to
install an SX-5, while making reference to MAP's
when necessary.
6.03 System Inspection, MAPZOO-001:
Inspect shipping carton for damage
If damaged return system
5.02 Telephone set and trunk cabling terminates Open shipping carton
on the SX-5 Terminal slrip. The station
loop limit is 600 ohms (including set) Tip to Ring, Remove equipment
and the Central Office trunk loop limit is 1600
ohms Check equipment against packing slip
