2.5.3 Pressurised systems

The following situations may result in serious injury or death:
• Contact with fast or suddenly escaping fluids
• Bursting system parts
• Pressurised hose and pipe whipping as a result of disconnection
For the safe handling of pressurised systems, observe the following:
• 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 the ambient pressure.
0 e.g. by slowly releasing the pressure in a controlled manner via relief valves
4. Lock out and tag out the system or system section so that it cannot be pressurised again.
• Check the pressurised system or system section for safety, contamination and possible damage.
• Before pressurisation, check all system connections for leak tightness and tighten if necessary.
• Make absolutely sure to charge the system or system section with pressure slowly.
• Avoid pressure hammer.
• 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 injury or death.
To ensure the safe handling of live components, observe the following:
• 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.
0 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 or the electronics housing
closed.
• Before starting work on the product:
1. Disconnect
0 Disconnect the product from all poles and all sides
2. Secure against restarting.
3. Determine the absence of voltage at all poles.
0 With suitable and permissible measuring device (e.g. two-pole voltage tester)
4. Earth and short circuit.
• Only the manufacturer is allowed to open the housing of the FRC control unit.
