• Staff must meet the following conditions for mounting, electrical installation,
commissioning and maintenance of the device:
– Be suitably qualified for their role and the tasks they perform
– Be trained in explosion protection
– Be familiar with national regulations (e.g. IEC/EN 60079-14)
• Install the device according to the manufacturer's instructions and the following standards:
– GB50257-1996 "Code for construction and acceptance of electric device for explosive
atmospheres and fire hazard electrical equipment installation engineering"
– GB3836.13-1997 "Electrical apparatus for explosive gas atmospheres – Part 13: Repair
and overhaul for apparatus used in explosive gas atmospheres"
– GB3836.15-2000 "Electrical apparatus for explosive gas atmospheres – Part 15:
Electrical installations in hazardous area (other than mines)"
– GB3836.16-2006 "Electrical apparatus for explosive gas atmospheres – Part 16:
Inspection and maintenance of electrical installation (other than mines)"
– GB15577-2007: "Safety regulations for dust explosion prevention and protection". (Only
if installed in dust hazardous areas.)
– GB12476.2-2006 "Electrical apparatus for use in the presence combustible dust – Part
1-2: Electrical apparatus protected by enclosures and surface temperature limitation –
selection, installation and maintenance". (Only if installed in dust hazardous areas.)
• Do not operate the device outside the specified electrical, thermal and mechanical
parameters.
• Only use the device in media to which the wetted materials have sufficient durability.
• Refer to the temperature tables for the relationship between the permitted ambient
temperature for the sensor and/or transmitter, depending on the range of application, and
the temperature classes.
• Modifications to the device can affect the explosion protection and must be carried out by
staff authorized to perform such work by Hauser.
• Observe all the technical data of the device (see nameplate).
• When using in hybrid mixtures (gas and dust occurring simultaneously), observe
additional measures for explosion protection.
Safety instructions:
Installation
• Continuous service temperature of the connecting cable: –40 to ≥ +80 °C; in accordance
with the range of service temperature taking into account additional influences of the
process conditions (T
a,min
and T
a,max
+ 20 K).
• Only use certified cable entries suitable for the application. Observe selection criteria as per
IEC/EN 60079-14. Accordingly, the connection terminal does not include any ignition
sources.
• Seal unused entry glands with approved sealing plugs that correspond to the type of
protection. The plastic transport sealing plug does not meet this requirement and must
therefore be replaced during installation.
• When material of the sensor is stainless steel this product can be used in Zone 1/2 (EPL is
Ga/Gb).
• This product shall be used in explosive gas atmospheres together with approved associated
apparatus, follow the instruction manual of this product and associated apparatus when
connecting the wiring. Connect the wiring terminals correctly.
• The external earth connection facility of the enclosure shall be connected reliably.
• The use shall not change the configuration in order to maintain/ensure the protection
performance of this product. Any change may impair safety.
Intrinsic safety
• The intrinsically safe input power circuit of the device is isolated from ground. If the device
is only equipped with one input, the dielectric strength of the input is at least 500 V
rms
. If
the device is equipped with more than one input, the dielectric strength of each individual
input to ground is at least 500 V
rms
, and the dielectric strength of the inputs vis-à-vis one
another is also at least 500 V
rms
.
• Observe the pertinent guidelines when interconnecting intrinsically safe circuits (e.g. IEC/
EN 60079-14, Proof of Intrinsic Safety).
