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.

WARNING
Risk of injury from objects falling and being ejected!
Falling and ejected objects during operation can lead to serious
injury or death.
•Take appropriate protective measures to secure the danger
zone.
WARNING
Risk of injury due to unexpected movements!
If the power supply is switched on or residual energy remains in
the system, components can move unexpectedly and cause
serious injuries.
•Before starting any work on the product: Switch off the power
supply and secure against restarting.
•Make sure, that no residual energy remains in the system.
WARNING
Risk of injury from sharp edges and corners!
Sharp edges and corners can cause cuts.
•Use suitable protective equipment.
WARNING
Risk of burns through contact with hot surfaces!
The product can heat up considerably during operation. Touching
hot surfaces can cause burns.
•Do not touch hot surfaces.
•Let them cool down before working on the product.
•Wear appropriate safety equipment.
WARNING
Risk of injury from objects falling during energy supply failure!
Electronic devices are not fail-safe. In case of an energy supply
failure, the gripping force decreases. As a consequence, it cannot
