3-2 Chapter 3: Site Preparation

Getting Started

The first step to preparing the selected site is to read the following two sections – About Site Preparation and Customer Responsibilities. These sections provide important information about NCR’s and your responsibilities to keep the NCR 7870 safe and in good working order.

The next step is to evaluate the chosen site for its suitability. As a minimum, these conditions need to be accessed:

Is the environment controlled within the 7870’s operational range for temperature, temperature change, relative humidity, barometric pressure, ambient light, acoustic noise, vibration, and shock?

Will other electronics be placed in checkstand which could necessitate use of forced air to regulate the temperature?

Will the power circuit to supply the 7870 be

dedicated to NCR equipment only and so labeled,

equipped with an isolated, insulated ground,

providing the required input to the Power Supply,

equipped with a recessed, 15-amp circuit breaker convenient to the checker, and

equipped with protection against voltage transients?

Is the checkstand

able to securely support the weight of the 7870 and

properly ventilated?

Has the plan for the checkstand design considered

use of a diverter or an adjustable plate,

clearance needed for service and customer viewing of display,

location and size of hole for cable routing, and

providing enough slack in cables so 7870 may be removed from checkstand for service without disconnection?
