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. Life threatening risks
may occur due to electrical voltages! Avoid personal or material damages by
observing applicable regulations and safety standards!
Other notes
The motor surface temperature may rise when maintaining, inspecting and repairing the actuator
immediately after the operation. There is a danger of burning the skin!
Always consult the relevant operating instructions when mounting PS 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.
General dangers of non-compliance with safety regulations
PSQ-E 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 at least
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 the safety regulations 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
Before opening the actuator cover, ensure that mains supply is isolated and prevented from unintended
re-connection.
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.
