2. Usage as per Specification
 PSL linear actuators are exclusively designed to be used as electric valve actuators. They are meant to be
mounted on valves in order to run their motors.
 Any other use is considered to be non-compliant and the manufacturer cannot be held liable for any damage
resulting from it.
 The actuators can only be used within the limits laid out in the data sheets, catalogues and other documents.
Otherwise, the manufacturer cannot be held liable for any resulting damage.
 Usage as per specification includes the observance of the operating, service and maintenance conditions laid
down by the manufacturer.
 Not to be regarded as usage as per specification are mounting and adjusting the actuator as well as servicing.
Special precautions have to be taken while doing this!
 The actuators may only be used, serviced and repaired by personnel that is familiar with them and informed
about potential hazards. The specific regulations for the prevention of accidents have to be observed.
 Damages caused by unauthorized modifications carried out on the actuators are excluded from the
manufacturer's liability.
 Supply voltage may only be switched on after the proper closure of the main cover or terminal box.
 Electrical wiring is done to a terminal block under the actuator cover.
3. Storage
For appropriate storage, the following instructions have to be met:
 Only store the actuators in ventilated, dry rooms.
 Store the actuators on shelves, wooden boards, etc., to protect them from floor moisture.
 Cover the actuators with plastic foil to protect them from dust and dirt.
 Protect the actuators against mechanical damage.
4. Operating Conditions
 Actuators with synchronous motors can fluctuate by up to +/-20% in the actuating force with +/-10% voltage
fluctuation.
 Standard actuators may be operated at ambient temperatures from -20°C to +60°C (S4 operation) or from -20°C
to +80°C (S2 operation).
 Operating modes correspond to DIN EN 60034-1, 8: S2 for short cycle and S4 for standard operation (for actuator
specific data see the table at the end of this document or the actuator specific data sheets)
 The permissible average force/torque over the entire travel is 50% of the max. thrust.
 For protection against moisture and dust, the enclosure rating is IP65 or IP67/IP68 according to EN 60529.
 When installing the actuators, leave enough space to allow cover removal (Fig.1).
 The actuator can be installed vertically or horizontally or any position in between. The actuator must not be
installed with the cover pointing downwards (Fig.2).
