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 and T2.
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-120/2 must only be used to calibrate the CEL-35X or
CEL-35X/IS in a non-hazardous atmosphere.
