3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any
• contingencies and events which may arise during the assembly, operation, and maintenance.
• local safety regulations – the operator is responsible for observing these regulations, also in relation to the instal-
lation personnel.
Risk of injury from high pressure.
▶ Before loosening lines and valves, cut off the pressure and deaerate or drain lines.
Risk of injury due to electrical shock.
▶ Before working on the system or device, switch off and isolate the power supply to prevent reactivation of the
device.
▶ Observe applicable accident prevention and safety regulations for electrical equipment.
Risk of burns or risk of fire if used for a prolonged duty cycle through hot device surface.
▶ Keep the device away from highly flammable substances and medium and do not touch with bare hands.
General hazardous situations.
To prevent injuries:
▶ Do not use Type 3280 and 3285 in potentially explosive areas.
▶ Do not subject the actuator housing and actuator cover to mechanical loading.
▶ Do not make any internal or external modifications on the device. Do not paint housing parts or screws.
▶ Avoid using the motor valve in the vicinity of strong magnetic fields.
▶ Secure the device from unintentional actuation.
▶ Only trained technicians may perform installation and maintenance work.
▶ After an interruption in the power supply, ensure that the process is restarted in a defined or controlled
manner.
▶ Observe the general rules of technology.
NOTE!
Electrostatic sensitive components and modules!
The device contains electronic components which react sensitively to electrostatic discharge (ESD). Contact with
electrostatically charged persons or objects are hazardous to these components. In the worst case scenario, they
will be destroyed immediately or will fail when energized.
• Observe the requirements in accordance with EN 61340-5-1 to minimize or avoid the possibility of damage
caused by sudden electrostatic discharge!
• Do not touch electronic components while the supply voltage is switched on!
