2 Chapter 2: 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
-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, electr
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.
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.
Chapter 2: Preparing the Installation Site 2-5 The following illustration shows an example of site wiring.
2-6 Chapter 2: Preparing the Installation Site 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.
