Power Connections for DC Systems
This section describes how to connect the power wires to the Coral IPx cage for DC
powered systems (that is, when the PS500 DC power supply card is installed in the
cage). For instructions on how to connect power wires to AC powered systems, see
page 1-45, Power Connections for AC Systems .
The DC power connection is made via a Molex receptacle on the top panel of the
PS500 DC. The top section of the cage includes a opening above the Molex receptacle
such that the cable with a Molex connector can be connected directly to the PS500 unit.
Each cage is connected directly to the customer’s DC power source and is protected by
a 16A/250V slow blow fuse that is located on the PS500 unit.
Connecting the Cage to the Facilities Power Source
The DC power cable provided with the system is 4.5 feet (1.5 meters) long.
Verify that the connection to the facilities power source is made according to
local requirements.
1. Do one of the following:
„
If the Coral IPx 500 system is located close enough to be connected to the
customer’s power supply with the supplied wires, skip to
Step 2 .
„
If the Coral IPx 500 system is not located close enough to the customer’s power
supply, fabricate a DC power connection from the DC facilities power source
up to a point that is close enough to connect the cage to the fabricated
connection with the supplied 4.5 ft (1.5m) long wire pair. Fabricate the
connection according to local requirements.
2. Connect the DC Molex wire pair into the receptacle of the PS500 unit via the
opening in the top section.
Electrical Fire Hazard. Do not interconnect several Coral IPx 500 cages together. Doing
so could result in currents that exceed the allowable limit and cause a fire. Connect each
cage directly to the facilities distribution panel. Likewise, verify that no more than up to
three cages of the Coral IPx 500 system are connected to the same circuit breaker
(rating:30 A, 250 V, slow blow).
