General notes
The device is to be assembled, started up or
operated only by trained and experienced per-
sonnel familiar with the product. According to
these mounting and operating instructions,
trained personnel is referred to as individuals
who are able to judge the work they are
assigned to and recognize possible dangers
due to their specialized training, their knowl-
edge and experience as well as their knowl-
edge of the applicable standards.
Explosion-protected versions of this device are
to be operated only by personnel who has un-
dergone special training or instructions or who
is authorized to work on explosion-protected
devices in hazardous areas.
Any hazards that could be caused in the valve
by the process medium, the signal pressure or
by moving parts are to be prevented by means
of the appropriate measures.
If inadmissible motions or forces are produced
in the pneumatic actuator as a result of the sup-
ply pressure level, it must be restricted using a
suitable supply pressure reducing station.
Proper shipping and appropriate storage are
assumed.
For technical data, ordering data, spare parts
and accessories see Data Sheet T 3776 EN.

Mounting
Before mounting to actuators, all
relevant parts of the plant must be
depressurized.
Due to the high surface resistance, avoid elec-
trostatic charging when mounting and servic-
ing the devices in hazardous areas.
Do not loosen enameled screws in or on the
housing.
Using mounting kits, the devices can be mount-
ed to rotary actuators, linear actuators and
control valves with ribs. Then the relevant
mounting instructions must be observed (see
pages 3 to 17).
To prevent water from entering the device, do
not mount the devices to rotary actuators or
control valves with ribs with the bottom of the
enclosure facing upwards. Install the exhaust
air filter in the enclosure cover and the cable
gland to face downwards or, if this is not pos-
sible, horizontally.
The devices can be mounted in any desired po-
sition to SAMSON Type 3277 Linear Actuators.
The required degree of protection
according to IEC 60529:1989 can
only be guaranteed when the enclo-
sure cover is mounted, the exhaust air filters
are installed and the connections are installed
properly.
Note: Devices with index 1 or lower have a
black enclosure cover with polyamide window.
Devices with device index 2 and higher have a
transparent polycarbonate enclosure cover.
On mounting make sure that at least 300 mm
space is left above the enclosure cover.
In locations where there is a risk of mechanical
damage to the enclosure, the enclosure must be
fitted with additional protection to fulfill the
requirements in clause 6 of EN 61241-0: 2006
“Electrical apparatus for use in the presence of
combustible dust“.
