6000 Series Purge/Pressurization System
I/O Manual
Warning Labels
WARNING - Conduit seal must be installed within 18
inches of the explosion-proof enclosure. To prevent
ignition of ammable or combustible atmospheres,
disconnect power before servicing.
WARNING - FOR ENCLOSURES IN HAZARDOUS
DUST ENVIRONMENTS
This enclosure shall not be opened unless the area
is known to be free of ammable materials or unless
all devices have been de-energized. Power must not
be restored after the enclosure has been opened until
combustible dusts have been removed and the enclosure
repressurized.
WARNING - FOR ENCLOSURES IN HAZARDOUS
GAS ENVIRONMENTS
This enclosure shall not be opened unless the area is
known to be free of ammable materials or unless all
devices have been de-energized. Power must not be
restored after the enclosure has been opened until the
enclosure is completely purged of all hazardous gas and
the enclosure repressurized.
WARNING - FOR ENCLOSURES IN HAZARDOUS
DUST AND GAS ENVIRONMENTS
This enclosure shall not be opened unless the area
is known to be free of ammable materials or unless
all devices have been de-energized. Power must not
be restored after the enclosure has been opened until
combustible dusts have been removed and completely
purged of all hazardous gas and the enclosure
repressurized.
Conditions of Safe Use
1. Conduit seals shall be certied in type of explosion
protection ameproof “db”, or explosion-proof Class
I/II Div 1 as required for the installation location
and suitable for the conditions of use. They shall be
correctly installed to the explosion-proof/ameproof
enclosure or conduit extensions as required. All NPT
threads are to be minimum 5 thread engagement,
wrench tight.
2. Seals shall be installed within 18 in. (450 mm) of the
explosion-proof/ameproof “db” enclosure.
3. When the purge control unit is mounted to an
enclosure, the complete unit shall be evaluated to
the current revision of IEC/EN 60079-2 or NFPA 496
as applicable. See certicates and/or Declaration of
Conformity for reference to relevant editions of these
standards.
4. The purge control unit has an operating temperature
class of 135 °C (T4 temperature class). This
temperature shall be considered when mounted to an
enclosure.
5. The device must be installed in accordance with the
manufacturer’s installation drawing number 116-B027.
6. Intrinsically safe cables extending from the explosion-
proof/ameproof "db" enclosure must be provided
with at least 0.25 mm insulation thickness per
conductive core to maintain segregation between
intrinsically safe circuits.
7. The cable entries may be used only in places
where they are protected against the inuence of
mechanical danger.
8. The non-metallic membrane touchpad and display is
a potential electrostatic discharge hazard. Use only
water damp cloth and allow to air dry for cleaning
device. Do not use or install in high charge areas.
See IEC 60079-32-1 for further information.
9. In hazardous dust environment, regularly remove dust
from the control unit enclosure to prevent excessive
temperature rise, including the solenoid valve.
10. Only pressure relief vent model EPV-6000-xx-xx
covered under the following certicates can be
used with devices covered by this certicate: For
ATEX applications: Certicate No. DEMKO 15
ATEX 1622X, DEMKO 07 ATEX 0705753X, or SIRA
09ATEX9337X. For IECEx applications: Certicate
No. IECEx UL 15.0147X, IECEx UL 08.0003X or
IECEx CSA 09.0007X. For cULus and cCSAus
applications: UL certication as part of le E184741
or CSA certication as part of 2205652 (LR90178).
11. For all applications, the 6000-TEMP-XX I.S.
temperature hub must be mounted in an enclosure
that is a minimum IP54. In hazardous dust
environment, the 6000-TEMP-xx temperature hub
has to be mounted in an enclosure that is certied
for the area classication. The pressurized enclosure
does not account for this type of enclosure because
power to this device is required before safe operation
within the pressurized enclosure. Maintain separation
of I.S. to non-I.S. wiring as required by local codes.
12. Caution must be used when handling or cleaning
products so there is no static charge buildup. Do not
wipe off the 6000-TSEN-xx sensor with dry cloth
or use in the presence of high charge generating
processes such as ionizers or electrostatic
equipment. See IEC 60079-32-1 for further
information.
13. The 6000 systems may also be provided with
previously certied items (operators, gable glands,
terminal box, etc.) as specied in the test reports.
14. Enclosure 6000-DPE-xx is only for I.S. termination
board 6000-ISB-xx and/or 6000-TEMP-xx.
I.S. Termination Board, DIN Mounted:
6000-ISB-xx
1. In hazardous dust environments, the I.S. termination
board, DIN mounted: 6000-ISB-xx must be mounted
in an enclosure that is certied for the area
classication. The pressurized enclosure does not
account for this type of enclosure because power to
this device is required before safe operation within
the pressurized enclosure.
2. Only connect to the 6000 EPCU I.S. termination
connection.
3. All wiring to and from this board is for intrinsically
safe connections and must be properly routed and
managed per international, NEC, local codes, and
applicable standards.
4. See the latest revision of installation drawing 116-
B027 for other important installation information.
5. The 6000-CBLA-… is not certied to be used in a
Zone 21 location. Use approved cable glands for this
area classication.
