Hazardous Locations Installations
Xycom Automation designed the systems with the intention of meeting the requirements
of Class I, Division 2 Hazardous Locations applications. Division 2 locations are those
locations that are normally non-hazardous, but potentially hazardous should an accident
expose the area to flammable vapors, gases or combustible dusts.
These systems are non-incendiary devices. They are not intrinsically safe and should never
be operated within a Division 1 (normally hazardous) location when installed as described
here. Nor should any peripheral interface device attached to these systems be located within
Division 1 locations unless approved and/or certified diode barriers are placed in series
with each individual signal and DC power line. Any such installations are beyond the
bounds of Xycom Automation design intent. Xycom Automation accepts no responsibility
for installations of this equipment or any devices attached to this equipment in Division 1
locations.
Note
It is the customer’s responsibility when adding additional cards that they
meet operating conditions for Class I, Division 2 hazardous locations.
It is the responsibility of the customer to ensure that the product is properly rated for the
location. If the intended location does not presently have a Class, Division, and Group
rating, then users should consult the appropriate authorities having jurisdiction in order
to determine the correct rating for that Hazardous Location.
In accordance with Federal, State/Provincial, and Local regulations, all hazardous loca-
tion installations should be inspected by the appropriate authority having jurisdiction
prior to use. Only technically qualified personnel should install, service, and inspect
these systems.
