General Requirements
The Coral IPx Office operates from a standard wide input of 100 to 240VAC, 47 to
63Hz source or from a –40 to –56VDC source.
1. Verify that electrical service is sufficient and located in close proximity to the
system. Coral IPx Office system requires at least one dedicated branch circuit
with at least two receptacles: one for the cage, and one for ancillary equipment
such as data terminals or personal computers, external paging equipment, or
test instruments, etc.
2. For 115VAC or 230VAC power, a 1.85mm 2 or 14AWG wire must be used in
the circuit branch.
3. Each branch circuit must be independently protected by a fuse or circuit
breaker, and must not be controlled by a switch. C-type fuses must be used
where required by local authorities.
4. The receptacle for the Coral system branch circuit must be located within
4 feet (1.2m) of the cage for AC operated systems, or within 4 feet (1.2m) of
the 48VDC power supply for DC operated systems.
5. Auxiliary branch circuit receptacles should be located conveniently for
ancillary equipment, and should allow data terminals, personal computers, or
test instruments to be operated near the system.
6. Table 2-4 lists the voltages and current requirements for each cabinet.
