,
GB 3836.2-2000
,
and
GB 12476.1-2000
standards.
Ex marking:
Ex d IIC T6~T2, DIP A21 T
A
(T85 °C ~ 265 °C) IP6X
Certificate:
GYJ101373
Special conditions for safe use:
1. The relationship between temperature class, ambient
temperature range, and process temperature range is as
follows:
Table B-13. 2130***M
Table B-14. 2130***E
2. The earth connection facility on the enclosure should be
connected reliably.
3. During installation in a hazardous location, cable glands,
conduits, and blanking plugs certified by state-appointed
inspection bodies (for Ex d IIC DIP A21 T
A
IP6X protection)
should be used.
4. During installation, use, and maintenance in explosive gas
atmospheres, observe the warning “Do not open when
energized”. During installation, use, and maintenance in an
explosive dust atmosphere, observe the warning “Do not
open when an explosive dust atmosphere is present”.
5. End users are not permitted to change any components
inside. (See
