2-2 Chapter 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.
Chapter 2: Preparing the Installation Site 2-3
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 DC power
from an external power supply that can support up to five CBSs. The
power supply's output is +24 VDC.
Note: Power requirements in EU/EC countries limit the number of
CBSs on one power supply to three (3).
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. 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 ground
connections to the distribution panel.
The following are the specifications for the CBS power supply:
Voltage (in) 100 to 240 Volts AC
Current (in) 3 Amps
Power (in) 100 Watts
Frequency 50 or 60 Hz
Voltage (out) 24 Volts DC
Current (out) 4.5 Amps
2-4 Chapter 2: 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
Be aware of the following power distribution requirements:
• All wire connections must be electrically and mechanically sound
and protected from deterioration. Deterioration due to corrosion or
electrolysis, especially in humid or corrosive atmospheres, may
result in electrical noise and/or a safety hazard.
• Electrical equipment such as wiring and circuit breakers cause
voltage drops in the power distribution system. Verify that the
voltage at each AC power outlet is within specification.
• Install AC power outlets in locations that are easily accessible and
as close as possible to the equipment they serve.
• Do not route power cords through openings with sharp edges or in
areas where they are exposed to sharp edges or pointy objects.
• Verify that all applicable national, state, and local codes are met.

Environmental Requirements
DecisioNet components operate across a wide range of environmental
conditions as shown in the following tables. Do not install these
components in locations 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.).
