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
remains and secure against inadvertent reactivation.
• The faulty actuation of conected drives may cause dangerous
movements.
• Operating mistakes, faulty parameterization during
commissioning or software errors may trigger dangerous
movements.
• 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
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, 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. Limit/
prevent accidental access for people in this area due through
technical safety measures. The protective cover and protective
fence must be rigid enough to withstand the maximum possible
movement energy. EMERGENCY STOP switches must be easily
and quickly accessible. Before starting up the machine or
automated system, check that the EMERGENCY STOP system is
working. Prevent operation of the machine if this protective
equipment does not function correctly.

2.13.4 Protection against electric shock
Work on electrical equipment
Touching live parts may result in death.
• Work on the electrical equipment may only be carried out by
qualified electricians in accordance with the electrical
engineering regulations.
• Lay electrical cables properly, e. g. in a cable duct or a cable
bridge. Observe standards.
• Before connecting or disconnecting electrical cables, switch off
the power supply and check that the cables are free of voltage.
Secure the power supply against being switched on again.
• Before switching on the product, check that the protective
earth conductor is correctly attached to all electrical
components according to the wiring diagram.
• Check whether covers and protective devices are fitted to
prevent contact with live components.
• Do not touch the product's terminals when the power supply is
switched on.
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
accordance 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
regulations.
• The effectiveness of the potential equalisation must be verified
by executing regular safety measurements.

2.13.5 Protection against magnetic and electromagnetic fields
Work in areas with magnetic and electromagnetic fields
Magnetic and electromagnetic fields can lead to serious injuries.
• Persons with pace-makers, metal implants, metal shards, or
hearing aids require the consent of a physician before entering
areas in which components of the electric drive and control
systems are mounted, started up, and operated.
• Persons with pace-makers, metal implants, metal shards, or
hearing aids require the consent of a physician before entering
areas in which magnetic grippers or motor parts with
permanent magnets are stored, repaired, or assembled.
• Do not operate high-frequency or radio devices in the proximity
of electric components of the drive system and their feed lines.
If the use of such devices is necessary:
When starting up the electric drive and control system, check
the machine or automated system for possible failures when
such systems are used at different intervals and in different
states of the control system. A special additional EMC test may
be necessary if the system has a high risk potential.
