AC Input Wiring
Options
There are various options available for input wiring for the -48V CPS
shelves:
•
Separate ac inputs for each power slot with connectors designated
as J1 through J5
•
Two ac inputs; one to power slots 1, 3, and 5 (connector J1) and one
to power slots 2 and 4 (connector J2)
•
One ac input distributed to all five power slots (connector J1)
•
Two ac input wire sets (10 feet long, extending from the rear of the
CPS shelf); one to power slots 1, 3, and 5, and one to power slots 2
and 4
•
One ac input distributed to all five power slots (terminal block
TB4)
Refer to Figure 5-4 for an illustration of the CPS input assemblies.
Warning
•
High leakage currents are possible. Earth ground connection is
essential before connecting the ac source to the shelf.
•
In enclosed equipment cabinets, the CPS mounting framework
must be connected directly to the cabinet ac service ground bus.
For applications in huts, vaults and central offices, the CPS
mounting framework must be connected to the system integrated
ground grid.
•
An accessible circuit disconnect must be provided that removes
power from all branch circuit inputs to the CPS.
•
AC input voltages are provided to CPS via multiple input cables.
Verify that the circuit protector for each ac input is disconnected
while servicing this equipment.
•
Interconnecting control/logic circuits are at hazardous voltage
levels with respect to ground.
