Pressurised systems
The following may result in serious personal injury or death:
•
Contact with fast or suddenly escaping fluids.
•
Bursting system parts.
•
Whipping movements of pressurized hoses and pipes during separation.
For the safe handling of pressurised systems, observe the following points:
•
Observe the following safety rules during all work:
1. Shut down the system or system section.
2. Secure the system or system section against restarting
3. Reduce the pressure in the system or all system sections to ambient pressure.
4. e.g. by slowly releasing the pressure in a controlled manner via relief valves.
5. Secure against pressure being applied again.
•
Check pressurised systems for safety, contamination and possible damage.
•
Before pressurisation, check all system connections for leak tightness and tighten if necessary.
•
Only pressurise systems slowly.
•
Avoid pressure blows and high differential pressures.
•
Compensate any vibrations occurring in the pipe network by using vibration dampers.
2.5.4
Electric voltage
Contact with live components may result in serious personal injuries or death.
To ensure the safe handling of live components, observe the following points:
•
Only connect the product and the accessories to the voltage supply if they are undamaged.
•
Comply with all regionally applicable regulations and requirements during installation.
•
Provide a circuit breaker in the power supply within easy reach of the product. The circuit breaker
disconnects all current-carrying conductors.
•
Connect the protective conductor (earth connection) according to regulations.
•
Only operate the product and accessories with the cover complete and closed and the electronics
housing closed.
•
Before starting work on the product:
1. Disconnect.
Disconnect the product from all poles and all sides.
2. Secure against restarting.
3. Determine the absence of voltage at all poles.
With suitable and permissible measuring device (e.g. voltage tester).
4. Earth and short circuit.
