Casella CEL-35X dBadge Users Handbook – Page 3
Instructions specific to hazardous area installations
(reference European ATEX Directive (94/9/EC, Annex II, 1.0.6.)
The following instructions apply to equipment covered by certificate
number Sira 07ATEX2032X for the CEL-35X/IS dBadge series:
The certificate number includes an ‘X’ suffix indicating that the
following special conditions of certification apply;
1. Parts of the enclosure are non-conducting and may generate
an ignition–capable level of electrostatic charge under
certain extreme conditions. The user should ensure that the
equipment is not installed or used in a location where it may
be subjected to external conditions (such as high-pressure
steam), which might cause a build-up of electrostatic charge
on non-conducting surfaces. Additionally, cleaning of the
equipment should be done only with a damp cloth.
2. The dBadge Noise Dosemeter shall not be used in areas
where a layer of coal dust may be deposited on the
enclosure.
3. The microphone should not be removed in a hazardous area.
4. The equipment may be used with flammable gases and
vapours with apparatus Groups IIA, IIB and IIC and with
temperature classes T1, T2, T3 and T4.
5. The equipment is only certified for use in ambient
temperatures in the range -20
o
C to +40
o
C and should not be
used outside this range.
6. Repair of this equipment shall only be carried out by the
manufacturer or in accordance with the applicable code of
practice.
7. If the equipment is likely to come into contact with aggressive
substances, then it is the responsibility of the user to take
suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection is not
compromised. Aggressive substances e.g. solvents may
affect polymeric materials.
8. Do not charge the batteries in a hazardous area. Only
charge the CEL-35X or CEL-35X/IS using the recommended
charger CEL-6362.
9. The CEL-110/2 must only be used to calibrate the CEL-35X
or CEL-35X/IS in a non-hazardous atmosphere.
