7 Safety Instructions: General

•The device is intended to be used in explosive atmospheres as defined in the scope

of IEC 60079-0 or equivalent national standards. If no potentially explosive atmospheres

are present or if additional protective measures have been taken:

The device may be operated according to the manufacturer's specifications.

•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)

•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 Pepperl+Fuchs.

•The probe is made of stainless steel or high corrosion-resistant alloy of thickness ≥ 1 mm.

8 Safety Instructions: Special Conditions

•Limitations of the maximum ambient temperature at the electronics housing

may be required dependent on device configuration, process temperatures

and temperature classification.

•Details of limitations: See section 10 for temperature tables.

•To avoid electrostatic charging: Do not rub surfaces with a dry cloth.

•In the event of additional or alternative special varnishing on the enclosure or other metal

parts or for adhesive plates:

•Observe the danger of electrostatic charging and discharge.

•Do not install in the vicinity of processes ( 0.5 m) generating strong electrostatic

charges.

Basic specification, feature Housing, option AX

Avoid sparks caused by impact and friction.

Device group IIC

•Sensors coated with non-conductive material can be used if avoiding electrostatic

charging (e. g. through friction, cleaning, maintenance, strong medium flow).

•Marked with warning sign: Avoid electrostatic charging.
