DC Powered Systems
This section describes how to connect the power wires to the Coral IPx Office unit for
DC powered systems (that is, when the PS Office DC power supply card is installed
in the unit).
Figure 2-28
shows one IPx Office unit installed within the system, and
Figure 2-29
shows three units 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 Office DC power supply unit is supplied with a 6.6ft (2m) long pair of
16 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 to the DC connection on the front panel of the
PS Office DC. Take care not to let the free end of the cable cause damage by
swinging loose or making contact with another electrical connection.
3. Do not insert the DC power input connector at this time. Leave the DC power
input connector unplugged.
4. Connect the other ends of the wires to the –48VDC facilities power source and
a circuit breaker as shown in
Figure 2-28
and
Figure 2-29
and according to
local regulatory requirements.
