Hazardous Locations Installation
Pro-face designed the 4600 series to meet the requirements of Class I and II,
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 Pro-face design intent. Pro-face accepts no responsibility for installations of this
equipment or any devices attached to this equipment in Division 1 locations.
Note
When additional cards are added, it is the customer’s responsibility to ensure
that the cards chosen meet operating conditions for Class I and II, Division 2
Hazardous Locations
.
Additions and/or modifications without express consent
from UL and/or Pro-face will void Hazardous Locations compliance.
It is the responsibility of the customer to ensure that the product is properly rated
for the location in which it is to be installed. 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.
Warning
In order to maintain a safe condition, do not attach an external keyboard or
mouse to the rear ports when the unit is operating in a hazardous environment.
Refer to the control drawing on page 36 for information on the front USB and
keyboard ports.
