The following describes the various forms of danger that can occur during machine operation.
Electricity
Touching voltage carrying components can result in electric shocks, burns or death.
➤ Allow only qualified and authorised electricians or trained personnel under the supervision of a
qualified and authorised electrician to carry out work on electrical equipment according to elec‐
trical engineering regulations.
➤ Before commissioning or re-commissioning the machine, the user must ensure adequate pro‐
tection against electric shock from direct or indirect contact.
➤ Before starting any work on electrical equipment:
Switch off and lock out the power supply isolator and verify the absence of any voltage.
➤ Switch off any external power sources.
These could be connections to floating relay contacts or the electrical machine heating, for ex‐
ample.
➤ Use fuses corresponding to machine power.
➤ Check regularly that all electrical connections are tight and in proper condition.
Forces of compression
Compressed air is contained energy. Uncontrolled release of this energy can cause serious injury
or death. The following information concerns work on components that could be under pressure.
➤ Close shut-off valves or otherwise isolate the machine from the distribution network to ensure
that no compressed air can flow back into the machine.
