2.3 Fundamental hazard potential
Fundamental hazard potentials exist. The specified examples draw atten-
tion to known hazardous situations, but are not complete and do not in any
way provide safety and risk awareness action in all situations.
2.3.1 Electrical hazards
Attention should be paid to electrical hazards particularly inside the compo-
nents in the area of all assemblies of the control system and motors of the
installation.
The following basically applies:
Have work on electrical equipment performed only by electricians or
trained persons under the direction and supervision of an electrician in
accordance with the electrotechnical regulations.
Always keep the control box and/or terminal box closed.
Before commencing work on electrical equipment, switch off the main
switch of the system and secure it against being switched back on in-
advertently.
Pay attention to the dissipation of residual energy from the control sys-
tem of the servomotors.
Make sure that the components are disconnected from the power sup-
ply when carrying out the work.
