Reference Manual
00809-0300-4101, Rev BB
Special Conditions for Safe Use (X):
1. If the equipment is fitted with an optional 90 V
transient suppressor, it is incapable of withstanding
the 500 V insulation from earth test and this must be
taken into account during installation.
2. The enclosure may be made of aluminium alloy and
given a protective polyurethane paint finish; however
care should be taken to protect it from impact and
abrasion when located in atmospheres that require
ELP Ga.

Special Conditions for Safe Use (X):
1. Symbol "X" is used to denote specific conditions of
use:
The Ex d blanking elements, cable glands, and

wiring shall be suitable for a temperature of 90 °C.
This device contains a thin wall diaphragm.

Installation, maintenance and use shall take into
account the environment conditions to which the
diaphragm will be subjected.
2. The relation between T code and ambient
temperature range is:

3. The earth connection facility in the enclosure should
be connected reliably.
4. During installation, use and maintenance of the
product, observe the warning "Don't open the cover
when the circuit is alive."
5. During installation, there should be no mixture
harmful to flameproof housing
6. Cable entry and conduit, certified by NEPSI with type
of protection Ex d IIC and appropriate thread form,
should be applied when installed in a hazardous
location. Blanking elements should be used on the
redundant cable entries.
7. End users are not permitted to change any internal
components, but to settle the problem in conjunction
with the manufacturer to avoid damage to the
product.
8. Maintenance should be done in a non-hazardous
location.
9. During installation, use and maintenance of this
product, observe the following standards:
GB3836.13-2013, GB3836.15-2000,
GB3836.16-2006, GB50257-2014.
