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.
12
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 scale.
Site Requirements
Before installing the MS2420 scanner/Avery 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 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 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/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
for detailed cutout dimensions and mounting instructions.

14
Service Access
When routing and installing the cable(s) and power supply, make sure to 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 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: Using 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 scanner 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.

Unpacking the Unit
1. Make sure the shipping box is topside up before opening.
2. Remove the accessories box and check the box’s content
for the following items.
Product Manuals
Power Supply
Communication Cables
Remote Scale Display (Optional)
3. Carefully remove the platter and store it in a safe location
until the unit is properly installed into the checkout counter.
Figure 11
4. Lift the MS2420 scanner out of the box by carefully
grasping both sides near the center of the unit and lifting
directly up. Refer to Figure 12 for hand placement.
Important! Do not remove the MS2420 scanner from the
box by grabbing the shipping foam. This can
result in the unit falling!
Figure 12
5. Carefully remove the shipping foam from around the
MS2420 scanner.
Figure 13
15

MS2420 Package Warning
All hardware securing the scale arms during shipping must be removed or the scale will not function!
Figure 14.
* Do not discard instructions and shipping hardware!
These items must be reinstalled if the unit is going to be shipped.
Installing the Unit in the Counter
Before starting to mount the MS2420 determine:
the scanner's orientation in reference to the operator and the direction of package flow,
the mounting method that provides the most stability for the scanner and
if any additional materials or tools are required for installation.
