Chapter 2: Preparing the Installation SitePreparing the SiteThis chapter provides the following information:• A summary of customer responsibilities prior to installation• Power, grounding, and distribution requirements of the DecisioNetSystem• DecisioNet System environmental requirements• DecisioNet System component characteristics2
2-2 Chapter 2: Preparing the Installation SiteCustomer ResponsibilitiesThe customer must do or provide the following:• When required by NCR, provide the NCR customer servicerepresentative with appropriate drawings that indicate:• Fixture Plan showing the location of store fixtures• Floor Plan showing the location of all interior walls, ceilingheights, and firewalls• Site wiring diagrams for power and communication• Location of other equipment capable of generating electricalnoise, electromagnetic interference, heat, etc.• Environmental conditions that could affect RF communication• Make building alterations necessary to meet wiring and other siterequirements• Provide and install all communications cables, wall jacks, specialconnectors, and associated hardware• Provide and install necessary power distribution boxes, conduits,grounds, lightning protection, and associated hardware• Provide and install auxiliary power or other equipment as required• Provide storage or service areas as required• Make sure that the environmental requirements discussed in thischapter are met• Provide floor coverings and environmental systems that limit orcontrol static electricity build-up and dischargeWarning: Make sure all applicable codes, regulations, and laws(including, but not limited to, electrical, building, safety, and health)are met.
Chapter 2: Preparing the Installation Site 2-3Power, Grounding and Distribution RequirementsVoltage transients, line noise, surges, sags, impulses, and spikes canhappen routinely or sporadically. When such phenomena occur,protective devices such as surge protectors may help to ensure properoperation of the equipment.Power RequirementsThe CBS does not have an internal power supply. It receives DC powerfrom an external power supply that can support up to five CBSs. Thepower supply's output is +24 VDC.Note: Power requirements in EU/EC countries limit the number ofCBSs on one power supply to three (3).For maximum system integrity, install the power supply(s) on adedicated branch circuit from a distribution panel that does not supplyany switched inductive loads (motors, air conditioners, etc.). Do notconnect anything else to this branch circuit except other DecisioNetSystem equipment. This branch circuit must remain "live" at all times.Each power supply circuit should consist of three conductors,including separate wires for the line, neutral, and insulated groundconnections to the distribution panel.The following are the specifications for the CBS power supply:Voltage (in) 100 to 240 Volts ACCurrent (in) 3 AmpsPower (in) 100 WattsFrequency 50 or 60 HzVoltage (out) 24 Volts DCCurrent (out) 4.5 Amps
2-4 Chapter 2: Preparing the Installation SiteGrounding RequirementsBecause the DecisioNet System connects logic reference ground tosafety ground, a noise-free grounding circuit is necessary for goodsystem integrity.Use an isolated ground receptacle, such as a Hubbell IG-5262 orequivalent. Make sure the ground conductor is insulated from conduitand neutral wire, and that it is connected to an insulated terminal stripat the distribution panel. DO NOT use this dedicated insulated groundwire as a neutral.DO NOT use a conduit as a ground. Resistance at the conduit jointsmay create multiple ground levels within the electrical powerdistribution system and degrade the reliability of the DecisioNetSystem.Power Distribution RequirementsBe aware of the following power distribution requirements:• All wire connections must be electrically and mechanically soundand protected from deterioration. Deterioration due to corrosion orelectrolysis, especially in humid or corrosive atmospheres, mayresult in electrical noise and/or a safety hazard.• Electrical equipment such as wiring and circuit breakers causevoltage drops in the power distribution system. Verify that thevoltage at each AC power outlet is within specification.• Install AC power outlets in locations that are easily accessible andas close as possible to the equipment they serve.• Do not route power cords through openings with sharp edges or inareas where they are exposed to sharp edges or pointy objects.• Verify that all applicable national, state, and local codes are met.

2-6 Chapter 2: Preparing the Installation SiteEnvironmental RequirementsDecisioNet components operate across a wide range of environmentalconditions as shown in the following tables. Do not install thesecomponents in locations where the temperature or humidity may gobeyond the limits indicated.Due to lower atmospheric pressure and air rarefaction at highaltitudes, the maximum dry bulb temperature for each working rangeis decreased linearly by a value of 3.3 °C /1,000m (1.8 °F /1,000 ft.)between the altitude of 500m (1,640 ft.) and 3,000 m (9,840 ft.).Temperature and HumidityThe environmental requirements for the CBS and ESLs are shown inthe following tables.CBSOperating Transit (1 week maximum) StorageTemperature(Dry bulb) 5°C to 45°C(40°F to 113°F) -40°C to 60°C(-40°F to 140°F) -10°C to 50°C(14°F to 122°F)Max.
