Qualified personnel
This instrument may only be installed and used by qualified personnel, strictly
in accordance with the technical data and the safety requirements and
regulations listed below. It is also essential to comply with the legal and safety
requirements for the application concerned during use. The same applies to
the use of accessories.
Qualified personnel means persons entrusted with the installation, assembly,
commissioning and operation of the product who possess the appropriate
qualifications for their function. Maintenance and repair work at the open, live
device may only be performed by trained personnel who are aware of the
potential danger.
CAUTION
Start‐up and installation are to be implemented only by technical personnel
for this special‐trained.
Installation of the devices outside the potential explosive atmosphere
S The Zener barriers are constructed to comply with protection class IP20
according to EN 60529 and must be protected accordingly from adverse
environmental conditions such as water spray or dirt exceeding the degree of
soiling 2.
S Zener barriers must be installed outside the potential explosive atmosphere!
S The intrinsically safe circuits of the devices (light blue marking at the devices)
can be - depending on the type of protection - conducted through potential
explosive atmospheres. In this connection, it is particularly important to ensure
the safe isolation of all non‐intrinsically safe circuits.
S When intrinsically safe field devices (load cells) are interconnected with the
intrinsically safe circuits of the related Zener barriers, the respective maximum
values for the field devices (load cells) and the Zener barriers - in the sense
of explosion protection - must be observed (proof of intrinsic safety).
EN 60079‐14 / IEC 60079‐14 has to be observed. For the Federal Republic of
Germany the national foreword of the DIN EN 60079‐14 / VDE0165 part 1 has
to be observed additionally.
S The EC Certificates of Conformity or EC‐Type Examination Certificates have
to be observed. It is especially important to observe the "Special conditions"
where these are contained in the certificates.
S When intrinsically safe circuits are used in explosive atmospheres caused by
dust (Ex‐Area 'D') only approved field devices (load cells) must be used.
