Safety instructions and measures
1 Safety instructions and measures
Intended use
TheType3375ElectricActuatorisdesignedtooperateamountedglobevalveusedinindus-
trial applications as well as in heating, ventilation and air-conditioning systems. The digital
positioner ensures a predetermined assignment of the valve position to the input signal. The
actuatorisdesignedtooperateunderexactlydenedconditions(e.g.thrust,travel).There-
fore, operators must ensure that the actuator is only used in operating conditions that meet
thespecicationsusedforsizingtheactuatorattheorderingstage.Incaseoperatorsintend
tousetheactuatorinotherapplicationsorconditionsthanspecied,contactSAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefertothetechnicaldataforlimitsandeldsofapplicationaswellaspossibleuses(see
'Technical data').
Reasonably foreseeable misuse
The actuator is not suitable for the following applications:
−Useoutsidethelimitsdenedduringsizingandbythetechnicaldata
Furthermore, the following activities do not comply with the intended use:
−Use of non-original spare parts
−Performing service and repair work not described
Qualicationsofoperatingpersonnel
The actuator must be mounted, started up, serviced and repaired by fully trained and quali-
edpersonnelonly;theacceptedindustrycodesandpracticesmustbeobserved.According
to these mounting and operating instructions, trained personnel refers to individuals who are
able to judge the work they are assigned to and recognize possible hazards due to their spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.

Safety instructions and measures
Personal protective equipment
No personal protective equipment is required for the direct handling of the electric actuator.
Work on the control valve may be necessary when mounting or removing the device.
ÎObservetherequirementsforpersonalprotectiveequipmentspeciedinthevalvedocu-
mentation.
ÎCheck with the plant operator for details on further protective equipment.
Revisionsandothermodications
Revisions,conversionsorothermodicationsoftheproductarenotauthorizedbySAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Safety features
The actuator has a thermal fuse which protects the asynchronous motor. The limit switches
automatically switch off the motor in the end positions. In actuators with fail-safe action, the
actuatorstemmovestoadenedendpositionuponsupplyvoltagefailure.Thefail-safeac-
tionofSAMSONactuatorsisspeciedontheactuatornameplate.
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the control valve by the process medium, the operat-
ing pressure, the signal pressure or by moving parts by taking appropriate precautions. Plant
operators and operating personnel must observe all hazard statements, warning and caution
notes in these mounting and operating instructions, especially for installation, start-up and
service work.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions to the operating per-
sonnel and to instruct them in proper operation. Furthermore, operators must ensure that op-
erating personnel or third parties are not exposed to any danger.

EB 8332-2 EN 1-3
Safety instructions and measures
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
wellasthespeciedhazardstatements,warningandcautionnotes.Furthermore,theoperat-
ing personnel must be familiar with the applicable health, safety and accident prevention
regulations and comply with them.
Referenced standards, directives and regulations
TheType3375ElectricActuatorfulllstherequirementsoftheDirectives2014/30/EUand
2014/35/EU.Thedeclarationofconformityincludesinformationabouttheappliedconfor-
mity assessment procedure. This declaration of conformity is included in the annex of these
instructions.
TheType3375ElectricActuatorisdesignedforuseinlowvoltageinstallations.
ÎFor wiring, maintenance and repair, observe the relevant safety regulations.

Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER
!
Risk of fatal injury due to electric shock.
ÎBefore connecting wiring, performing any work on the device or opening the de-
vice, disconnect the supply voltage and protect it against unintentional reconnec-
tion.
ÎOnly use power interruption devices that can be protected against unintentional re-
connection of the power supply.
ÎDo not remove any covers to perform adjustment work on live parts.
Risk of bursting in pressure equipment.
Valves and pipelines are pressure equipment. Improper opening can lead to valve
components bursting.
ÎBefore starting any work on the control valve, depressurize all plant sections affect-
ed as well as the valve.
ÎDrain the process medium from all the plant sections affected and from the valve.
ÎWear recommended personal protective equipment (see associated valve docu-
mentation).
1.2 Notes on possible personal injury
WARNING
!
Crush hazard arising from moving parts.
The electric actuator contains moving parts (actuator and plug stems), which can injure
handsorngersifinsertedintotheactuator.
ÎDonotinserthandsorngerintotheyokewhilethevalveisinoperation.
ÎDisconnect the supply voltage and protect it against unintentional reconnection be-
fore performing any work on the control valve.
ÎDo not impede the movement of the actuator or plug stem by inserting objects into
their path.
