Preparing the Installation Site

Preparing the Site
This chapter provides the following information:
• A summary of customer responsibilities prior to installation
• Power, grounding, and distribution requirements of the DecisioNet
System
• DecisioNet System environmental requirements
• DecisioNet System component characteristics

3-2 Preparing the Installation Site

Customer Responsibilities
The customer must do or provide the following:
• When required by NCR, provide the NCR customer service
representative with appropriate drawings that indicate:
• Fixture Plan showing the location of store fixtures
• Floor Plan showing the location of all interior walls, ceiling
heights, and firewalls
• Site wiring diagrams for power and communication
• Location of other equipment capable of generating electrical
noise, electromagnetic interference, heat, etc.
• Environmental conditions that could affect RF communication
• Make building alterations necessary to meet wiring and other site
requirements
• Provide and install all communications cables, wall jacks, special
connectors, 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 this
chapter are met
• Provide floor coverings and environmental systems that limit or
control static electricity build-up and discharge

Warning: Make sure all applicable codes, regulations, and laws
(including, but not limited to, electrical, building, safety, and health)
are met.

Power, Grounding and Distribution Requirements
Voltage transients, line noise, surges, sags, impulses, and spikes can
happen routinely or sporadically. When such phenomena occur,
protective devices such as surge protectors may help to ensure proper
operation of the equipment.

Power Requirements
The CBS does not have an internal power supply. It receives +60V DC
from an external power supply (7710-K100). Each power supply can
support up to five CBSs.
For maximum system integrity, install the power supply(s) on a
dedicated branch circuit from a distribution panel that does not supply
any switched inductive loads (motors, air conditioners, etc.). Do not
connect anything else to this branch circuit except other DecisioNet
System equipment.
Each power supply circuit should consist of three conductors,
including separate wires for the line, neutral, and insulated ground
connections to the distribution panel.
The specifications for the CBS power supply are as follows:

Voltage 100 to 240 Volts
Current 1.1 to 2.2 Amps
Watts 130 Watts
Frequency 50 or 60 Hz

3-4 Preparing the Installation Site

Grounding Requirements
Because the DecisioNet System connects logic reference ground to
safety ground, a noise-free grounding circuit is necessary for good
system integrity.
Use an isolated ground receptacle, such as a Hubbell IG-5262 or
equivalent. Make sure the ground conductor is insulated from conduit
and neutral wire, and that it is connected to an insulated terminal strip
at the distribution panel. DO NOT use this dedicated insulated ground
wire as a neutral.
DO NOT use a conduit as a ground. Resistance at the conduit joints
may create multiple ground levels within the electrical power
distribution system and degrade the reliability of the DecisioNet
System.

Power Distribution Requirements
The following power distribution requirements must be met to
minimize the effects of electrical noise generated by equipment outside
of the DecisioNet System:
• Give consideration to voltage drops in the power distribution
system caused by wiring, circuit breakers, terminal blocks, etc..
Verify that the voltage at the receptacle is within the specifications
on the power supply and that all applicable national, state, and
local codes are met.
• All wire connections must be electrically and mechanically sound
and protected from deterioration. Deterioration of wire connections
due to corrosion or electrolysis, especially in a humid or corrosive
atmosphere, may result in electrical noise and/or a safety hazard.

Environmental Requirements
CBSs, SmarTalkers, and SmarTalker IIs operate across a wide range of
environmental conditions as shown in the following tables. Avoid
using them in continuous operation at or near the temperature limits
shown in the tables or in a location where the temperature or humidity
may go beyond the limits indicated.
Due to lower atmospheric pressure and air rarefaction at high
altitudes, the maximum dry bulb temperature for each working range
is 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.).

The environmental requirements for the CBS, SmarTalker, and
SmarTalker II tags are shown in the following tables.
