1Safety 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, elec-
trical connection, commissioning and operation are met at the place of installation.
Depending on the device version, this includes:
• Standards and directives such as IEC60079:
Part 14: Electrical installations design, selection and erection.
Part 17: Electrical installations inspection and maintenance.
• Configuration guidelines for the respective fieldbus or network applications.
Safety instructions/warn-
ings
All personnel working with this device must be familiar with the safety and warning in-
structions in this manual and heed 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 re-
garding 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. Highly efficient charge
generating processes will lead to propagating brush discharges and therefore to igni-
tion of a potentially explosive atmosphere. This safety instruction also applies to fire-
proof coatings or covers available as an option.
When using a stem protection tube, any type of charge generating processes must be
excluded at its protective cap as well as the V-seal (e.g. only wipe with a damp cloth).
Otherwise, ignitable electrostatic discharges might occur.
Ignition hazards Gearings were subjected to an ignition hazard assessment in compliance with the cur-
rently 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 protection level of enclosure protection 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.
• Heed recognised rules for occupational health and safety.
• Heed national regulations.

Safety instructions
5
• During operation, the housing warms up and surface temperatures > 60°C may
occur. To prevent possible burns, we recommend checking the surface temperat-
ure using an appropriate thermometer and wearing protective gloves, prior to
working on the device.
Protective measures The end user or the contractor are responsible for implementing required protective
measures on site, such as enclosures, barriers, or personal protective equipment for
the staff.
Maintenance To ensure safe device operation, the maintenance instructions included in this manual
must be observed.
Any device modification requires prior written consent of the manufacturer.
1.2 Range of application
AUMA part-turn actuatorsSAEx/SAREx are designed for the operation of industrial
valves, e.g. globe valves, gate valves, butterfly valves, and ball valves.
The devices described below are approved for use in the potentially explosive atmo-
spheres of zones 1, 2, 21, and 22.
If temperatures > 40°C are to be expected at the valve flange or the valve stem (e.g.
due to hot media), please consult AUMA.
Temperatures > 40 °C are not considered with regards to the non-electrical explosion
protection.
Other applications require explicit (written) confirmation by the manufacturer.
The following applications are not permitted, e.g.:
• Industrial trucks according to EN ISO 3691
• Lifting appliances according to EN 14502
• Passenger lifts according to DIN 15306 and 15309
• Service lifts according to EN 81-1/A1
• Escalators
• Continuous duty
• Buried service
• Continuous underwater use (observe enclosure protection)
• Potentially explosive areas of zones 0 and 20
• Potentially explosive areas of group I (mining)
• Radiation exposed areas in nuclear power plants
No liability can be assumed for inappropriate or unintended use.
Observance of these operation instructions is considered as part of the device's desig-
nated use.
These operation instructions are only valid for the “clockwise closing” standard ver-
sion, i.e. driven shaft turns clockwise to close the valve. For “counterclockwise closing”
version, a supplement must be observed in addition to these operation instructions.
Particular conditions of use
The particular conditions of use are listed on the certificates supplied. Among others,
this includes the following conditions:
• For further references to minimise the risk of electrostatic charging within a poten-
tially explosive atmosphere, refer to Prerequisites for the safe handling of the
product [}4].
• For information regarding the dimensions of the flameproof joints, contact the
manufacturer.
• Special fasteners according to IEC 60079-0 to seal flameproof enclosures must
have the following strength classes:
