0.5VDC drop in voltage from the iDCS 500 and the batteries. Ensure polarity prior to
connecting the external –48VDC power source to the system.
The -48VDC cable assembly has a male 3 pin mate and lock connector on the system
end
(see Figure 2–7) . Insert this end of the DC cable into the battery (BATT) connector
on the left hand side of the cabinet. Attach the other end of the DC power cable to the –
48VDC power source.
WARNING : Be sure the proper polarity is observed. Equipment damage will result if
polarity is reversed. Do not connect external AC or DC power to the System (see
Section 4 Power Up Procedures).
2.9 MDF CABLING
All connections to the iDCS 500 system are made by way of a customer-provided main
distribution frame (MDF). Each interface card (with the exception of the TEPRI, MGI,
E911 cards) is connected to the MDF using a 25 pair female amphenol-type cable.
These cables can be routed into the iDCS 500 cabinet(s) from below or on the right
side of the cabinet.
Label each cable to correspond with the slot numbers
(see Figure 2–5) . Label each 66
type terminating block to identify the cabinet, slot and port numbers. Use one pair
twisted jumper wire to cross-connect stations or lines to their associated port.
