EX-B05-1EN
4. Installation of Flameproof Equipment
(1) Installation Area
Flameproof equipment may be installed,
in accordance with applicable gases, in a
hazardous area in Zone 1 or 2, where the
speciedgasesarepresent.Thoseequipment
shall not be installed in a hazardous area in
Zone 0.
Note: Hazardousareasareclassiedin
zones based upon the frequency of
the appearance and the duration of an
explosive gas atmosphere as follows:
Zone 0: Place in which an explosive
atmosphere consisting of a mixture with
airofammablesubstancesintheform
of gas or vapour is present continuously
or for long periods or frequently.
Zone 1: Place in which an explosive
atmosphere consisting of a mixture with
airofammablesubstancesintheform
of gas or vapour is likely to occur in
normal operation occasionally.
Zone 2: Place in which an explosive
atmosphere consisting of a mixture with
airofammablesubstancesintheform
of gas or vapour is not likely to occur in
normal operation but, if it does occur,
will persist for a short period only.
(2) Environmental Conditions
To comply with the ambient temperature
range which indicated on the nameplate. If the
ameproofequipmentareexposedtodirect
sunshine or radiant heat from plant facilities,
appropriate thermal protection measures shall
be taken.
5. External Wiring for Flameproof
Equipment
Flameproof equipment requires cable wiring for
their electrical connections. For cable wiring, cable
glands(cableentrydevicesforameprooftype)to
wiring connections shall be attached. All non-live
metal parts such as the enclosure shall be securely
grounded. For details, read USER’S GUIDELINES
for Installations for Explosive Atmospheres in
General Industry.
(1) Cable Wiring
• Forcablewiring,Excableglandsattached
(or supplied) with the electrical equipment
of Flameproof enclosure shall be used and
connected to conduit.
• Speciccablesshallbeusedasrecommended
by the USER’S GUIDELINES for Installations
for Explosive Atmospheres in General Industry.
• Innecessary,appropriateprotectivepipes
(conduitorexiblepipes),ductsortraysshall
be used for preventing the cable run (outside
the cable glands) from damage.
• Topreventexplosiveatmospherefrombeing
propagated form Zone 1 or 2 hazardous
location to any different location or non-
hazardous location through the protective pipe
or duct, apply sealing of the protective pipes
neartheindividualboundaries,orlltheducts
with sand appropriately.
• Whenbranchconnectionsofcablesorcable
andconduitwiringismade,aameproof
connection box shall be used. In this case,
ameproofcableglandsmeetingthetype
of connection box must be used for cable
connections to the box.
IMPORTANT
The electrical equipment of Flameproof
enclosureiscertiedtobeusedwiththe
attached Ex cable gland(s). Therefore, the
attachedExcablegland(s),Yokogawa-specied
Ex cable gland, shall be used to satisfy this
requirement.
