Site Power Wiring Recommendations - Pearson OpScan iNSIGHT 70 Installation Manual

With circuit power on and all OpScan iNSIGHT 70 system components
unplugged, the voltage between the circuit neutral conductor and the isolated
ground conductor must be less than 0.6 VAC.

Site Power Wiring Recommendations

Table 2-2 describes the conditions for power wiring at a scanner site.
Table 2-2 Power Wiring at a Scanner Site
Condition Description
Dedicated Run a separate dedicated feeder from the building main power panel to the
Feeder branch power panel serving the OpScan iNSIGHT 70 system. The cabling
should be of sufficient diameter to produce no less than 110V at the outlet
when the scanner is connected and powered on. This feeder should be a
minimum of 30 amp service to allow for future growth of the system.
Dedicated
An isolated/dedicated ground is required. Run this ground conductor as an
Isolated/ uninterrupted circuit from the power panel to the OpScan iNSIGHT 70
Insulated system branch panel. The gauge of this conductor must be at least as large as
Ground that of the AC circuit conductors in all stages of the circuit.
Panel Branch All branch circuits leaving the OpScan iNSIGHT 70 branch power panel
Circuits
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 scanner 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 Provide additional convenience outlets in the vicinity of the OpScan
Convenience
iNSIGHT 70 scanner. Connect these outlets (may be used for vacuums,
Connectors
paper joggers, and other electrical devices) to a branch panel other than the
scanner branch panel to provide maximum noise isolation for the OpScan
iNSIGHT 70 system components.
Scanner Dedicate one 15 amp (120 VAC) or 7.5 amp (220 VAC) circuit to each
Electrical OpScan iNSIGHT 70 scanner at the site. All may be served from the same
Connections
branch panel, provided its rated capacity is not exceeded.
Electrical All 120V outlets for the OpScan iNSIGHT 70 scanner should be Hubble
Outlets 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.
