3 Product description

For safety and warranty reasons, any invasive
work on the device beyond that described in the
operating instructions manual may be carried
out only by personnel authorised by the manu-
facturer. Arbitrary conversions or modifications
are explicitly forbidden. For safety reasons, only
the accessory specified by the manufacturer
must be used.
To avoid any danger, the safety approval mar-
kings and safety tips on the device must also be
observed.
2.5 Safety according to EU
directives
The device fulfils the legal requirements of the
applicable EU directives. By affixing the CE
marking, we confirm the conformity of the instru-
ment with these directives.
The EU conformity declaration can be found on
our homepage.
Electromagnetic compatibility
The instruments are designed for use in an
industrial environment. Nevertheless, electro-
magnetic interference from electrical conduc-
tors and radiated emissions must be taken into
account, as is usual with a class A instrument
according to EN 61326-1.
When the device is mounted in metal con-
tainers or tubes, the interference resistance
requirements of IEC/EN 61326 for "Industrial
environment" and the NAMUR recommendation
EMC (NE21) are met.
If the device is to be used in other environ-
ments, the electromagnetic compatibility to
other devices must be ensured by suitable
measures.
