Hazardous Locations Installations
Xycom Automation designed the systems to meet the requirements of Class I,
Division 2 Hazardous Locations applications. Division 2 locations are those
locations that are normally non-hazardous, but could become hazardous due to
accidents that may expose the area to flammable vapors, gases or combustible dusts.
These systems have been designed as 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 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
locations installations should be inspected by the appropriate authority having
jurisdiction prior to use. Only technically qualified personnel should install, service,
and inspect these systems.
