SITE REQUIREMENTS
Power Installation
The Power Supply (AC/DC) should be connected to an AC Outlet that is free of electrical noise (clean). A qualified electrician
can determine the amount of electrical noise on the AC line. See additional information on power installation and restrictions
under the Installation: Interface section of this manual.
Metrologic recommends using a switched AC outlet. The switch should be located on the operator’s side of the
checkout counter in close proximity to the MS2420 to facilitate calibration and service of the unit.
Checkout Counter Layout Considerations
When placing a scanner in a checkout counter, the following factors should be considered.
• Items should flow at a distance to the operator that maximizes comfort. The operator should not need to stretch or strain
to reach for and scan packages.
• The MS2420 can scan a bar code on five sides of a package. The packages should flow into the scan area that provides
the maximum reading performance. No lifting or orientation of the items is necessary. A properly placed item diverter can
maximize the flow of packages.
• In what direction are the packages flowing? Most checkout counters are designed for left-handed takeaway. If the
operator is facing the vertical window of the scanner, packages flow from the operator's right to left. The packages are in
queue on the conveyor to the right and the bagging is to the left.
