B Hazardous Location
Installations
Xycom Automation designed the 3015 to meet Class I, Division 2 Hazardous Location
application requirements. Division 2 locations are locations that are normally non-haz-
ardous, but could become hazardous due to accidents that may expose the area to
flammable vapors, gases, or combustible dusts.
These units have been designed as nonincendive 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 units 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.
It is the customer’s responsibility 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 to de-
termine 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 authority having jurisdiction, prior to
use. Only technically qualified personnel should install, service, and inspect these
units.

Suitable for use in Class I, Division 2, Groups A, B, C, and D, and Class II,
Division 2, Groups F and G hazardous locations or non-hazardous locations only.

teriel inacceptable pour les emplamements de classe I, II, Division 2.
