• 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 national regulations.
• 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.
• Avoid electrostatic charging:
– Of plastic surfaces (e.g. housing, sensor element, special varnishing , attached additional plates, ..)
– Of isolated capacities (e.g. isolated metallic plates)
• 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 class.
• Modifications to the device can affect the explosion protection and must be carried out by staff
authorized to perform such work by Endress+Hauser.
• When replacing the probe electronics or opening the connection between the remote cable and the
probe, a jumper plug must be used or a short-circuit must be established between the probe contact
and the potential equalization conductor to avoid electrostatically charging the probe.
• After mounting and connecting the probe, ingress protection of the housing must be at least IP65 in
accordance with EN 60529.
Perform the following to achieve the degree of protection:
– Screw the cover tight.
– Mount the cable entry correctly.
Permitted ambient temperature range at the electronics housing: –40 °C  T
Observe the information in the temperature tables.
• In the case of process connections made of polymeric material or with polymeric coatings, avoid
electrostatic charging of the plastic surfaces.
• In the event of additional or alternative special varnishing on the housing or other metal parts:
– Observe the danger of electrostatic charging and discharge.
– Do not rub surfaces with a dry cloth.
