Safety-related information
– Observe the specifications and restrictions in the Instructions for Use and/ or
data sheets for the sensors.
– CAUTION Risk of ignition of flammable or explosive atmospheres! Not tested in
oxygen enriched atmospheres (>21% O
2
).
– Using the product in areas subject to explosion hazards: Instruments or
components for use in explosion-hazard areas which have been tested and
approved according to national, European or international Explosion Protection
Regulations may only be used under the conditions specified in the approval
and with consideration of the relevant legal regulations.
Hazardous areas classified by divisions:
– The device is intended to be used in hazardous areas Class I, Div. 1 or Div. 2,
where gases of groups A, B, C, D and temperature class T4 or T6 may be
present. Temperature classes depend on the maximum ambient temperature.
The device must not be operated within ambient temperatures outside the
temperature range marked on the device.
– The device is intended to be used in hazardous areas Class II, Div. 1 or Div. 2,
where dusts of groups E, F, G may be present. The device must not be operated
within ambient temperatures outside the temperature range marked on the
device.
Hazardous areas classified by zones:
– The device is intended to be used in hazardous areas classified Zone 1 or Zone
2 where gases of explosion groups IIA, IIB or IIC and temperature class T4 or T6
may be present. Temperature classes depend on the maximum ambient
temperature. The device must not be operated within ambient temperatures
outside the temperature range marked on the device.
– The device is intended to be used in hazardous areas classified Zone 21 or
Zone 22 where dusts of explosion Groups IIIA, IIIB or IIIC and dust temperatures
of T80°C or T130°C (T135°C for Polytron
®
5100 EC and Polytron
®
8100 EC)
may be present. Dust temperatures depend on the maximum ambient
temperature. The device must not be operated within ambient temperatures
outside the temperature range marked on the device.
2.3 Mechanical installation
– Strict compliance must be given to the local, state, national codes and
regulations that govern the installation of gas monitoring equipment.
– The physical data of the gas or vapor to be detected and the specifics of the
application, (e.g. possible leaks, air movement/draft, etc.) must be taken into
account.
– The future use of accessories and maintenance equipment must be kept in
mind.
– The access of the gas or vapor to the sensor must not be obstructed.
– The instrument must not be exposed to radiant heat that will cause the
temperature to rise beyond the limits stated in 17.6 Environmental parameters.
The use of a reflecting shield is recommended.
