Parker PowerStation XT Series, User Manual

Orientation and Clearance Guidelines
Select an enclosure that is large enough to allow free airflow in and around the XT/IX/PCA PowerStation.
Allow a minimum of two inches between the inside of the enclosure and the top, bottom, and sides of the
PowerStation to allow access to the mounting clamps, sufficient air circulation and cable clearance. Verify
that the surface of the enclosure on which the PowerStation is mounted is flat and free of raised or
depressed areas.
Consider additional clearance below the PowerStation to allow efficient cable access and routing and to
allow for insertion and removal of cables.
Mount the PowerStation in a vertical orientation to allow for proper ventilation.
WARNING: Failure to follow these guidelines may result in overheating of the
PowerStation.
Radiated Emissions Guidelines
The XT/IX/PCA family of PowerStations have been tested to comply with international electromagnetic and
emission standards (EN55022 and ICES-003 FCC Part 15 Class A). To reduce radiated emissions, ensure
that there is a low impedance earth connection to the PowerStation, which can be accomplished by
utilizing Pin-3 on the input power connector. This connection must be made with the shortest possible,
heavy gage wire or braided cable. Low-resistance (<0.5 ohms) continuity should be verified with an
ohmmeter for proper grounding. In addition, all communication cables should be shielded and grounded,
preferably only on one end.
Earth Grounding Guidelines
To minimize unwanted electrical interference, select a location away from equipment that produces
intense electrical noise (motor drives, for example). Use good engineering practices and isolate input
power to the unit and separate all data communication cables from AC power lines.
Important: Use the PowerStation ground terminal (Pin-3 on the input power
connector) to connect the unit to a suitable ground reference, such as
earth ground or building steel. This ensures the unit is in compliance
with immunity and emissions requirements necessary for proper
operation.
Switching inductances from relays, contactors, solenoids, or switching magnets can produce significant
surge voltages. It is necessary to reduce these inductive spikes to a minimum whenever possible, which
may require diodes, Z-diodes, varistors, or RC elements. We recommend that you contact the
manufacturer or supplier of the corresponding actuators relevant information regarding surge protection.
