The Coral IPx 500 can operate as an AC powered system or as a DC powered system.

DC Powered Systems
This section describes how to connect the power wires to the Coral IPx 500 cage for
DC powered systems (that is, when the PS500 DC power supply card is installed in the
cage).
Figure 2-42
shows one IPx 500 cage installed in the system, and
Figure 2-43
shows three cages installed within the system.
The DC power wires provided with the system are 6.6ft (2m) long. Verify that
the connection to the facilities power source is made according to local
requirements.
1. The PS 500 DC power supply unit is supplied with a 6.6ft (2m) long pair of
14 AWG wires (one red and one black). If this is not long enough to connect the
facilities power source to the cage, fabricate an extension at the customer’s site
with two wires that are identical to the ones above.
2. Route each power wire through one of the slots at the rear panel of the top section
of the cage. Take care not to let the free end of the cable cause damage by
swinging loose or making contact with another electrical connection. Leave
approximately 12” (30cm) of wire length within the cage to reach the DC power
input connection.
3. Do not insert the DC power input connector at this time. Leave the DC power
input connector unplugged on the cage top section.
4. Connect the other ends of the wires to the -48VDC facilities power source and a
circuit breaker as shown in
Figure 2-42
and
Figure 2-43
and according to local
regulatory requirements.
