General Requirements
The Coral IPx 500 operates from a standard wide input 100-240VAC, 47-63Hz source or
from a -48VDC source. AC powered units can be supplied with a built-in backup
battery for 1 hour of operation.
1.
Verify that electrical service is sufficient and located in close proximity to the
system. Coral IPx 500 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 should 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.
