Install and Wire the Panel
This chapter provides you with an overview of the installation and wiring of
the DataSite configured panel.
Environment and Enclosure
Most applications require installation in an industrial enclosure to reduce the
effects of electrical interference and environmental exposure. Locate your
controller as far as possible from power lines, load lines, and other sources of
electrical noise such as hard-contact switches, relays, and AC motor drives. For
more information on proper grounding guidelines, see the Industrial
Automation Wiring and Grounding Guidelines, publication
.
Hazardous Location
Considerations
The DataSite configured panel is UL Listed for use in hazardous locations
Class I Division 2, groups A, B, C, and D, or non-hazardous locations only.
Proper installation must be considered for the panel to be used in these
locations. Installation of the panel should be done only after ensuring the
location is free of any hazardous gases or substances. For proper installation
refer to articles 500, 504 and 505 of the National Electric Code, NFPA 70,
2005.
The following WARNING statement applies to use in hazardous locations.
ATTENTION
Be careful of metal chips when drilling mounting holes for your
controller or other equipment within the enclosure or panel.
Drilled fragments that fall into the controller could cause
damage. Do not drill holes above a mounted controller if the
protective debris strips have been removed.
WARNING
Explosion Hazard
•
Substitution of any component may impair suitability for Class I
Division 2.
•
Do not disconnect equipment while the circuit is live or unless
the area is known to be free of ignitable concentrations.
•
Batteries must only be changed in an area known to be
non-hazardous.
