Optional specifications
No options specific to hazardous locations are available.
• Comply with the installation and safety instructions in the manual.
• 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
• 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)
• In the case of process connections made of polymeric material or with polymeric coatings, avoid
electrostatic charging of the plastic surfaces.
• For light metal flanges or flange faces (e.g. titanium, zirconium), avoid sparks caused by impact
and friction.
• 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.
