• Contingencies and events which may arise during the installation,
operation and maintenance of the devices.
• Local safety regulations – the operator is responsible for observing
these regulations, also with reference to the installation personnel.
DANGER!
Danger – high pressure!
▶Before loosening the lines and valves, turn off the pressure and
vent the lines.
Risk of electric shock!
▶Before reaching into the device or the equipment, switch off the
power supply and secure to prevent reactivation!
▶Observe applicable accident prevention and safety regulations
for electrical equipment!
WARNING!
Danger of bursting from overpressure!
▶Observe the specifications on the type label for max. control
and medium pressure.
▶Observe permitted medium temperature.
CAUTION!
Risk of burns/risk of fire if used continuously through hot
device surface!
▶Keep the device away from highly flammable substances and media
and do not touch with bare hands.
General hazardous situations.
To prevent injury, ensure that:
▶The system cannot be activated unintentionally.
▶Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
▶After an interruption in the power supply or pneumatic supply,
ensure that the process is restarted in a defined or controlled
manner.
▶The device may be operated only when in perfect condition and
in consideration of the operating instructions.
▶The general rules of technology apply to application planning
and operation of the device.
