Caution: To maintain compliance with applicable standards, all circuits connected to the imager must
meet the requirements for SELV (Safety Extra Low Voltage) according to EN/IEC 60950-1.
To maintain compliance with standard CSA C22.2 No. 60950-1/UL 60950-1 and norm
EN/IEC 60950-1, the power source should meet applicable performance requirements for a
limited power source.

Installation
Quick Installation Outline
The following is a quick preview of the steps required for first time installations. Each item is discussed in
detail later in this section.
Determine clearance, ventilation and service access requirements.
Determine checkout counter layout taking into account package flow, cable routing, and power
requirements.
Choose the mounting option which provides the best cable/power access and unit stability.
Unpack the unit.
Make the appropriate countertop cutouts and install all support brackets.
Place the unit in the counter.
Install the platter.
Follow the steps under the correct interface to connect the cables and power supply.
Configure the unit for the correct interface.
Calibrate the Diva scale.
Site Requirements
Before installing your MS2420/MS2430 scanner/Diva scale, please consider the following items.
Vertical Clearance
A minimum clearance height of 5.25" from the checkout counter surface is needed for the vertical 'hood' on all
of the scanner models.
Ventilation and Spacing
All MS2420 and MS2430 models have a die-cast housing to dissipate heat allowing the unit to operate without
a ventilation fan. The temperature surrounding the unit is recommended not to exceed 40°C (104°F). There
should be adequate convection and minimal heat producing equipment in close proximity of the unit.
A cooling fan with a filter is recommended if there will be a conveyor motor or other heat producing equipment
close to the unit that will create a high temperature environment.
Adequate spacing between the unit and the checkout counter opening is required for proper operation of the
scale. When the scanner/Diva scale model is mounted properly, the scale platter should be able to move up
and down freely without hitting the edges of the checkout counter cutout. Refer to Installing the Unit in the
Counter beginning on page 18 of this guide for detailed cutout dimensions and mounting instructions.

16
Site Requirements
Service Access
When routing and installing the cable(s) and power supply, make sure you leave access that these
components may be swapped easily without the need to remove the unit from the checkout counter.
When changing the StratosSWAP optics engine modules, removing the unit completely from the checkout
counter is recommended.
When calibrating or zeroing the scale, do not remove the unit from the checkout counter. Refer to the Scale
Operation Section beginning on page 47 of this guide for detailed instructions on zeroing and calibration.
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.
Note: A switched AC outlet is recommended. The switch should be located on the operator’s side of the
checkout counter in close proximity to the MS2420/MS2430 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 and MS2430 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.
