Page 3: Safety Instructions
• Safety instructions The actuators described below are part of a power plant installation for industrial applications. They are designed in accordance with the generally applicable technical regulations. The connection and start-up of the linear actuators requires expert knowledge on the installation of power systems and equipment (according to DIN VDE 0100), on accident prevention regula- tions and the special start-up conditions for linear actuators. -
Page 4: Principle Of Operation
DANGER! During installation and operation, suitable power supply systems must be used to ensure that hazardous voltages are prevented from energizing the device in standard operating mode or in case of a faulty system or system parts. Otherwise, personal injury and/or property damage may result. Any hazards which could be caused by the process medium, the signal pressure and moving parts of the control valve are to be prevented by means of appropri- ate measure. -
