Chapter 2: Installing the PowerStation Selecting a Location

Environmental Guidelines

The environment is the area where the PA PowerStation will be located. In general, you should select a place that limits the unit’s exposure to adverse conditions such as dust, oil, moisture, and corrosive vapors.

Touchscreen Considerations

The PA PowerStation’s touchscreen is designed to meet the NEMA 4/4X rating. However, it is only rated NEMA 4/4X when properly mounted in a NEMA 4/4X enclosure.

The PA PowerStation’s touchscreen is resistant to a variety of chemicals. See Faceplate Chemical Resistance on page A-8 for a list of these chemicals. Make sure that the touchscreen is not exposed to chemicals other than those listed in Faceplate Chemical Resistance on page A-8.

Electrical Guidelines

To minimize unwanted electrical interference, select a location away from machinery that produces intense electrical noise. If you cannot do this, isolate input power to the unit and separate all data communication cables used with the unit from all AC power lines.

All serial communication cables should be 100% shielded with the shield tied to chassis ground at one end of the cable only.

See Electrical Specifications on page A-6 for a list of the PA PowerStation’s electrical specifications. Make sure that your power source is compatible with the PowerStation before starting the unit.

Field Terminal Wiring Requirements

In order to comply with UL 508 and 1604 requirements, use copper wire with 60C or 60/75C insulation and a tightening torque of 7.0 lb/in. (0.79 N- m) when connecting field terminal wiring to the PowerStation.

Temperature and Humidity Guidelines

You can safely operate the PA PowerStation within the temperature range specified in Environmental Specifications on page A-5. However, if you are using a protective enclosure, remember that the temperature within an enclosure is generally higher than the external temperature. Read these guidelines to fully understand temperature implications.

The PA PowerStation can dissipate no more than 10 watts maximum.

Heat builds up rapidly in enclosed environments, compromising the performance and life span of electrical equipment. If the PowerStation is operating inside an enclosure at temperature levels above its rated ambient temperature, you must cool the enclosure.
