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

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.
