General dangers of non-compliance with safety regulations
PSF actuators are built at state-of the art technology and are safe to operate. Despite of this, the actuators may be
hazardous if operated by personnel that has not been sufficiently trained or minimum instructed, and if the
actuators are handled improperly, or not used as per specification.
This may
cause danger to life and limb of the user or a third party,
damage the actuator and other property belonging to the owner,
reduce safety and function of the actuator.
To prevent such problems, please ensure that these operating instructions and this chapter in particular have been
read and understood by all personnel involved in the installation, commissioning, operation, maintenance and repair
of the actuators.
Basic safety notes
The actuators may only be operated by skilled and authorized operating personnel.
Make sure to follow all security advices mentioned in this manual, any national rules for accident prevention, as
well as the owner´s instructions for work, operation and safety.
The isolating procedures specified in these operating instructions must be followed for all work pertaining to the
installation, commissioning, operation, change of operating conditions and modes, maintenance, inspection,
repair and installation of accessories.
Areas that can be under voltage have to be isolated before working on them.
Ensure that the actuators are always operated in faultless condition. Any damage or faults, and changes in the
operational characteristics that may affect safety, must be reported at once.
Danger signs
The following danger signs are used in this operating manual:
Caution! There is a general risk of damage related to health and/or properties.
Danger! Electrical voltages are present that may lead to death.
This sign warns of hazards posing a risk to health. Ignoring these instructions can lead to
injuries.
Attention! Observe precautions for handling. Electrostatic sensitive devices.
Other notes
The motor surface temperature may rise when maintaining, inspecting and repairing the actuator immediately
after operation. There is a danger of burning the skin!
Always consult the relevant operating instructions when mounting PS-S accessories or operating the actuator
with PS accessories.
Connections for signal in- and output are double isolated from circuits that can be under dangerous voltage.
