Safety instructions
1.1.
Prerequisites for the safe handling of the product
Standards/directives
The end user or the contractor must ensure that all legal requirements, directives,
guidelines, national regulations and recommendations with respect to assembly,
electrical connection, commissioning and operation are met at the place of installation.
They include among others:
●
Standards and directives such as IEC 60079 “Explosive atmospheres":
-
Part 14: Electrical installations design, selection and erection.
-
Part 17: Electrical installations inspection and maintenance.
●
Applicable configuration guidelines for fieldbus applications.
Safety instructions/
warnings
All personnel working with this device must be familiar with the safety and warning
instructions in this manual and observe the instructions given. Safety instructions
and warning signs on the device must be observed to avoid personal injury or property
damage.
Qualification of staff
Assembly, electrical connection, commissioning, operation, and maintenance must
be carried out by suitably qualified personnel authorised by the end user or contractor
of the plant only.
Prior to working on this product, the staff must have thoroughly read and understood
these instructions and, furthermore, know and observe officially recognised rules
regarding occupational health and safety.
Work performed in potentially explosive atmospheres is subject to special regulations
which have to be observed. The end user or contractor of the plant is responsible
for respect and control of these regulations, standards, and laws.
Electrostatic charging
Highly efficient charge generating processes (processes more efficient than manual
friction) on the device surface must be excluded at any time, since they will lead to
propagating brush discharges and therefore to ignition of a potentially explosive
atmosphere.
This also applies to fireproof coatings or covers available as an option.
Ignition dangers
Gearboxes were subjected to an ignition hazard assessment in compliance with the
currently applicable standard according to ISO 80079-36/ -37. Hot surfaces,
mechanically generated sparks as well as static electricity and stray electric currents
were identified and assessed as major potential ignition sources. Protective measures
to prevent the likelihood that ignition sources arise were applied to the gearboxes.
This includes in particular lubrication of the gearbox, the IP protection codes and the
warnings and notes contained in these operation instructions.
Commissioning
Prior to commissioning, imperatively check that all settings meet the requirements
of the application. Incorrect settings might present a danger to the application, e.g.
cause damage to the valve or the installation. The manufacturer will not be held
liable for any consequential damage. Such risk lies entirely with the user.
Operation
Prerequisites for safe and smooth operation:
●
Correct transport, proper storage, mounting and installation, as well as careful
commissioning.
●
Only operate the device if it is in perfect condition while observing these instruc-
tions.
●
Immediately report any faults and damage and allow for corrective measures.
●
Observe recognised rules for occupational health and safety.
●
Observe national regulations.
●
During operation, the housing warms up and surface temperatures > 60 °C may
occur. To prevent possible burns, we recommend checking the surface temper-
ature prior to working on the device using an appropriate thermometer and
wearing protective gloves.
