Special Conditions for Safe Use (X):
1. This device contains a thin wall diaphragm. Installation, maintenance
and use shall take into account the environmental conditions to which
the diaphragm will be subjected. The manufacturer's instructions for
installation and maintenance shall be followed in detail to assure
safety during its expected lifetime.
2. Flameproof joints are not intended for repair.
3. Non-standard paint options may cause risk from electrostatic
discharge. Avoid installations that could cause electrostatic build-up
on painted surfaces, and only clean the painted surfaces with a damp
cloth. If paint is ordered through a special option code, contact the
manufacturer for more information.
4. Some variants of the equipment have reduced markings on the
nameplate. Refer to the Certificate for full equipment marking.

Special Conditions for Safe Use (X):
1. If the apparatus is fitted with an optional 90 V transient suppressor, it
is not capable of withstanding the 500 V insulation test required by
clause 6.3.12 of IEC60079-11. This must be taken into account when
installing the apparatus.
2. The enclosure may be made of aluminum alloy and given a protective
polyurethane paint finish; however, care should be taken to protect it
from impact or abrasion if located in Zone 0.
