Ensuring safety
Ensuring safety
Follow the instructions below for safe installation.
Warning instructions are located before a potentially dangerous task.
Disregard of warning instructions can cause serious injuries!
Please take note of all safety instructions
Disregard of safety notes can cause unforeseeable dangers!
➤ Follow the instructions in chapter 3 'Safety and Responsibility'.
➤ Installation work may only be carried out by authorized personnel.
➤ Make sure that no one is working on the machine.
➤ Ensure that all service doors and panels are locked.
When working on live components
Touching voltage carrying components can result in electric shocks, burns or death.
Dangerous voltages persist in the frequency converter and intermediate circuit capacitors for some
time after power is switched off.
Live components are exposed when the frequency converter cabinet is opened.
➤ Work on electrical equipment may only be carried out by authorized electricians.
➤ Switch off and lock out the power supply isolating device and verify the absence of voltage.
➤ Before starting work on the frequency converter or intermediate circuit capacitors, wait at least
5 minutes.
➤ Check that there is no voltage on potential-free contacts.
When working on the compressed air system
CAUTION
For transport and short-term storage, the machine is filled in the factory with gas with an
overpressure of 0.5 bar.
➤ De-pressurise all pressurised components and enclosures.
Compressed gas is contained energy. Uncontrolled release of this energy can cause serious injury
or death. The following safety concerns relate to any work on components that could be under
pressure.
➤ Close shut-off valves or otherwise isolate the machine from the gas network to ensure that no
compressed gas can flow back into the machine.
➤ De-pressurise all pressurised components and enclosures.
➤ Check all machine gas hose connectors with a hand-held pressure gauge to ensure that all
read zero.
➤ Do not open or dismantle any valves.
