Power voltage may be present both at the product and at the machine or system if the safety relay is switched
off.
Ö
Disconnect the unit from the power supply and discharge all residual current from it just as you would for a
device without a safety relay.
Health hazard from deficient safety units
Disassembling safety units during repair and maintenance of the machine or system can cause serious injury or
death.
Ö
Restore the safety devices to their original functional condition and check their functionality immediately after
completing repair and maintenance tasks.
WARNING
Health hazard caused by automatic starting
When work is being carried out on the machine or system, there is the danger that it might start automatically.
This can cause serious injury!

Switch off the superordinate power supply and secure it from restarting (main switch for the overall systems).
Ö
Make sure that no one is located in the danger zone before the machine or system is switched back on
again!

CAUTION:
Damage to product from electrostatic discharge
The high voltages in the machine or system generate electrostatic charges that may damage electronic
components!

Personnel must be grounded before starting repair work or maintenance work on the machine or system by
means of a ground cable or by touching a conductive, grounded object.
Damage to the product as a result of blowing out using compressed air
Never clean the quick-change tool adapter with compressed air when it is in an installed state. When this is
