General
• Observe safety distances.
• Never deactivate safety devices.
• Before commissioning the product, take appropriate protective
measures to secure the danger zone.
• Disconnect power sources before installation, modification,
maintenance, or calibration. Ensure that no residual energy
remains in the system.
• If the energy supply is connected, do not move any parts by
hand.
• Do not reach into the open mechanism or movement area of
the product during operation.
2.12.1 Protection during handling and assembly

2.12.2 Protection during commissioning and operation
Falling or violently ejected components
Falling and violently ejected components can cause serious injuries
and even death.
• Take appropriate protective measures to secure the danger
zone.
• Never step into the danger zone during operation.
2.12.3 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.
