4 Cabling specifications
This section provides an overview of the cabling requirements for the
Intelligent Peripheral Equipment Column (IPEC). It includes connections to
external power sources, internal power distribution, Extended System Monitor
(XSM) alarms cabling, switchboard cabling, ground cabling, and cabling card
cage modules.
Power cable requirements
An IPEC is powered by an external -48 V dc power supply. The Meridian
Power Distribution Center (MPDC) provides dc power to the IPE lineup,
which is separate from the standard SL-100 cabinet lineup. Power feeder
cables (#6 AWG wire) between the MPDC and the IPEC must not exceed 52
feet.
Terminating equipment power feeders and returns
Terminating equipment power feeders and returns for the IPEC and for the
Meridian Power Distribution Center (MPDC) are described and illustrated
below.
IPEC
Direct current (dc) power for the pedestal (NT7D09CA) provides circuit
protection of 30 amps for BAT0 and BAT1 feeds and 30 amps for BAT2 and
BAT3 feeds (see "Direct current power distribution" on page 4-2).
The -BAT (-48 V dc cable) wiring from the MPDC connects to terminal block
TB1 in the bottom of the pedestal. One #6 AWG wire feeds -48 V dc to two
IPEs, a total of two wires for BAT connections (see "Terminal Block Harness
(TB1) wiring diagram" on page 4-3).
•
IPE 0 and IPE 1 are connected to BAT 0/1 (-48 V dc[A])
•
IPE 2 and IPE 3 are connected to BAT 2/3 (-48 V dc[B])
The BAT RTN (48 V dc cable) wiring from the MPDC connects to terminal
block TB1 in the bottom of the pedestal. One #6 AWG wire feeds +48 V dc
to two IPEs, a total of two wires for BAT RTN connections (see "Terminal
Block Harness (TB1) wiring diagram" on page 4-3).
•
IPE 0 and IPE 1 are connected to BAT RTN 0/1 (BR[A])
•
IPE 2 and IPE 3 are connected to BAT RTN 2/3 (BR[B])
