Site Power Wiring Recommendations
The table below describes the conditions { XE "Scanner installation:Site power wiring
recommendations" } { XE "Power wiring recommendations" } for power wiring at a scanner site.
Condition Description
Dedicated Feeder Run a separate dedicated feeder from the building main power panel to
the branch power panel serving the 5000
i system. The cabling should be
of sufficient diameter to produce no less than 110V at the outlet when
the 5000
i is connected and powered on. This feeder should be a
minimum of 30 amp service to allow for future growth of the system.
Dedicated Isolated/
Insulated Ground An isolated/dedicated ground is required. Run this ground conductor as
an uninterrupted circuit from the power panel to the 5000
i system branch
panel. The gauge of this conductor must be at least as large as that of
the AC circuit conductors in all stages of the circuit.
Panel Branch Circuits All branch circuits leaving tne 5000 i branch power panel should be at
least 10 AWG copper wire. There should be no circuits from this power
panel serving devices that are not part of the 5000
i system.
One branch circuit from this power panel should be dedicated at the
scanner (this circuit will also service the computer and monitor), and
there should be at least one additional dedicated circuit for each
additional scanner.
Additional Utility
Convenience Connectors Provide additional convenience outlets in the vicinity of the 5000 i
scanner. Connect these outlets (may be used for vacuums, paper
joggers, and other electrical devices) to a branch panel other than the
scanner branch panel to provide maximum noise isolation for the 5000
i
system components.
Scanner Electrical
Connections Dedicate one 15 amp (120 VAC) or 7.5 amp (220 VAC) circuit to each
5000
i scanner at the site. All may be served from the same branch
panel, provided its rated capacity is not exceeded.
Electrical Outlets { XE
"Electrical outlet" \i }
All 120V outlets for the 5000 i scanner should be Hubble IG-5362 or
equivalent (NEMA 5-20R). All 240V outlets should be Hubble IG2410A
or equivalent. Outlets for the peripheral equipment should be of the type
and rating specified in the hardware reference manuals for the
equipment.
The quantity of outlets that must be provided for the peripheral
equipment varies according to system configuration. (See Panel Branch
circuits above.) Outlets should be located within 6 feet (2 meters) of the
working location of the equipment.
