Standards: GB3836.1-2000, GB3836.2-2010, GB12476-2000
Markings: Ex d IIC T6/T5, T6(-50°C ≤ Ta ≤ +65°C), T5(-50°C ≤ Ta ≤ +80°C)
Special Conditions of Use (X):
1.
The relation between ambient temperature arrange and temperature class is as follows:
Ta Temperature Class

When used in a combustible dust environment, the maximum ambient temperature is
80°C.
2.
The earth connection facility in the enclosure should be connected reliably.
3.
Cable entry certified by notified body with type of protection Ex d IIC in accordance wi
th
GB3836.1
-2000 and GB3836.2-2000, should be applied when
installed in a hazardous
location. When used in combustib
le dust environment, cable entry in accordance wi
th
IP66 or highe
r level should be applied.
4.
Obey the warning “Keep tight when the circuit is alive.”
5.
End users are not permitted to change any internal
components.

Certificate: GYJ13.1362X; GYJ101312X [Flowmeters]
Standards: GB3836.1-2010, GB3836.4-2010, GB3836.20-2010, GB12476.1-2000
Markings: Ex ia IIC Ga T4/T5
Special Conditions for Safe Use (X):
1.
Symbol “X” is used to denote specific conditions of
use:
a.
If the apparatus is fitted with an optional 90V trans
ient suppressor, it is not capable
of
withstanding the 500V insulation test for 1 minute. This must be ta
ken into
account w
hen in
stalling the apparatus.
b.
The enclosure may be made of aluminum alloy and given a protective polyuretha
ne
paint finish; however, care should
be taken to prot
ect it from impact or abrasion if
located in Zone 0
.
