2.13.3 Protection against dangerous movements
Unexpected movements
Residual energy in the system may cause serious injuries while
working with the product.
• Switch off the energy supply, ensure that no residual energy re-
mains and secure against inadvertent reactivation.
• Never rely solely on the response of the monitoring function to
avert danger. Until the installed monitors become effective, it
must be assumed that the drive movement is faulty, with its ac-
tion being dependent on the control unit and the current oper-
ating condition of the drive. Perform maintenance work, modi-
fications, and attachments outside the danger zone defined by
the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Re-
strict unintentional access by persons to this range e.g. via a
protective cover, protective fence or photoelectric barrier. The
protective cover and protective fence must be rigid enough to
withstand the maximum possible movement energy. EMER-
GENCY STOP switches must be easily and quickly accessible.
Check the function of the EMREGENCY STOP before starting up
the machine or system. If this protective equipment is not work-
ing properly, prevent the operation of the machine.
2.13.4 Protection against electric shock
Possible electrostatic energy
Components or assembly groups may become electrostatically
charged. When the electrostatic charge is touched, the discharge
may trigger a shock reaction leading to injuries.
• The operator must ensure that all components and assembly
groups are included in the local potential equalisation in accord-
ance with the applicable regulations.
• While paying attention to the actual conditions of the working
environment, the potential equalisation must be implemented
by a specialist electrician according to the applicable regula-
tions.
• The effectiveness of the potential equalisation must be verified
by executing regular safety measurements.
