Special Conditions For Safe Use (X):
1. When the equipment is used in a hazardous area, the programming port must not be
used.
2. The metal enclosure must be electrically connected to a grounding terminal. The driver
used for the connection must be equivalent to a copper cable with 4 mm
2
section.
The apparatus is not capable of withstanding the 500 V test as defined in Clause 6.3.12
of ABNT NBR IEC 60079-11. This must be considered in any installation.
3. The 3300 Series enclosure may be made of aluminium 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.
4. The probes may contain plastic materials greater than 4 cm
2
or be coated with plastic
and these can present an electrostatic risk if rubbed or placed in a fast moving air flow.
5. The probes may contain light alloys which can present a risk from frictional ignitions.
Care should be taken to protect them from mechanical impact during use or
installation.
