Basic safety instructions
Explosion hazards
The unit has been designed and manufactured taking the har-
monised standards EN1127-1, EN60079-0 and EN60079-1 into
account. Thus, the unit is protected against potentially-
explosive atmospheres by a pressure-resistant flameproof
enclosure “d”.
In spite of this, the following points must be observed:
An explosion hazard arises from using equipment that is
unsuitable for the environmental conditions.
Before use in an environment in which there is an explosion
hazard, observe the following points:
The surface temperature of the equipment must not ex-
ceed that permissible at the location where it is installed.
If the unit is installed so that it is electrically isolated, suit-
able measures must be adopted to discharge static elec-
tricity between valve connections.
Moving parts that are extremely resistant to movement, may
give rise to frictional heating. Ensure that moving parts move
freely.
During welding operations, there is a risk of explosion or fire
being caused by open flames, electric arcs and flying
sparks. Observe the valid legal regulations concerning pro-
tection against fire and explosions that apply where the unit
is installed.
The unit and its components shall only be assembled or
dismantled by specialist personnel.
Danger of serious injury
The unit can become hot during operation. Only take the unit
into service when contact with hot surfaces is prevented by
insulation or guards.
During operation the unit is under the influence of higher
ambient temperatures and may be hot. Do not carry out
work on the unit until the following conditions apply:
The unit has been disconnected from sources of electrical
energy.
The unit has cooled down (to about 20°C).
During any work on the unit, the higher-level plant must
be switched off and secured against unauthorised switch-
ing back on.
For units installed in contaminated areas, there is a danger
of severe or lethal injury from hazardous substances on the
unit. Do not work on the unit until it has been completely de-
contaminated. Wear the specified protective clothing during
all work in the contaminated area.
The unit and its components shall only be assembled or
dismantled by specialist personnel. Specialist personnel
must have knowledge and experience in the following sec-
tors:
Qualified electrician
The selection of lifting gear suitable for the unit, and the
safe use of such lifting gear
Working with hazardous media (contaminated, hot, or un-
der pressure)
The selection of unsuitable lifting gear, or its incorrect use,
can result in the unit or parts of it falling.
Allow only specialist personnel to lift the unit or its parts.
Make sure that there are never persons under suspended
loads.
Make sure that lifting gear has adequate load capacity for
the load it has to lift, and that such loads are properly at-
tached.
Make sure that all valid, local safety and accident-
prevention regulations are observed.
If the permissible application limits for the unit are exceeded,
the unit may be destroyed, and hot or pressurised media
may be released. Make sure that the unit is always operated
within the permissible application limits.
Details of the application limits are given on the unit’s typep-
late and in the chapter “
Technical data ”
If it is used without supports with adequate load capacity and
sufficiently stable connections to the valve, the unit may be
damaged. Allow only specialist personnel to assemble and
connect the unit.
If the unit is inadequately supported during installation, sub-
stantial injuries (e.g. crushing) are possible if the unit falls or
tips. During installation secure the unit to prevent it falling or
tipping. Wear the protective clothing specified at the location.
The unit can be installed on several different types of valve,
e.g. a ball valve or a butterfly valve. Depending on the ener-
gy source for the drive, there is a danger of severe or lethal
injuries from a variety of causes. Before starting any work on
the unit, make sure that it is disconnected from the power
supply, and that the valve and its pipework are pressure-
free. Observe and follow all hazard notes in the operating in-
structions for the valve. If you have any queries, please con-
tact the valve manufacturer.
There is a danger of severe or lethal crushing by moving
parts of the unit. During operation, make sure that no one
can be in the vicinity of the moving parts or reach into them.
Before any work on the unit, make sure the actuator is

Installing the unit
Mount the unit on a ball valve, butterfly
valve or ball valve combination
Valves supplied by the manufacturer
have a drive coupling that fits the actua-
tor. For other valves, the connection must
comply with the requirements of
DIN EN ISO 5211, and the actuator must
be equipped with a suitable adapter.
For more information about available
and possible valves, please contact
the manufacturer.
Valves must be correctly mounted.
When you install the actuator on a valve,
ensure that the position of the ball / but-
terfly valve or similar device and the
position of the actuator agree. When the
valve is open, the notch in the actuator
drive shaft must be in the 90° or 270°
position (or 0° or 180° if mounted trans-
versely) (there are degree markings on
the cover of the actuator).
Regarding the position indicator of an
actuator for installation on a multi-way
valve or a valve combination, please
contact the manufacturer.
The connection between the actuator and
the valve should be either direct or by
means of a special actuator connection.
There must always be a drive coupling
on a valve. The mountings for an actua-
tor and an actuator coupling on a valve
are not always identical.
The number of mounting screws depends
on the actuator type. This section shows
the actuator mounted on a multi-way
valve.
The type of mounting on your unit is
shown on the drawings supplied.
Please contact the manufacturer if you
need more information about mount-
ing the actuator.

19
To mount the unit on a valve, proceed as follows:
Make sure that the actuator connection (21) is securely attached to the actuator
(1).
Tighten the nuts (24) to the correct torque.
Place the actuator (1) on the valve stem 23) or the extension (20).
Tighten the screws (22 or nuts 24) on the valve.

20
The torque to tighten the screws or nuts
depends on their size.
The tightening torques in the following
table [Nm] should be considered as a
guide, because in practice the coefficient
of friction may vary substantially. The
following data are based on
a coefficient of friction of 0.1-0.14.
Tighten the screws or nuts to the
specified torque.
