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.
Site Requirements
Before installing your MS2421/MS2422/MS2431 bar code scanner, 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
The MS2421/MS2422/MS2431 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.
Service Access
When routing and installing the cable(s) and power supply, make sure you leave access so 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.
