WARNING
Danger to life when live parts are touched
Death or serious injury can result when live parts are touched.
•
Only work on electrical equipment if you are appropriately qualified.
• Always comply with the local national safety regulations when working on electrical
equipment.
Generally, six steps apply when establishing safety:
1.
Prepare for shutdown and notify all those who will be affected by the procedure.
2. Disconnect the machine from the power supply.
– Switch off the machine.
– Wait until the discharge time specified on the warning labels has elapsed.
– Check that it really de-energized, from phase to phase and phase to protective
conductor.
– Check that every auxiliary circuit is de-energized.
– Ensure that the motors cannot move.
3. Secure SIMOTICS motors against unintentional movements that generate a voltage at
the terminals.
4. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems or
water.
5. Isolate or neutralize all hazardous energy sources, for example by closing switches,
grounding or short-circuiting, or closing valves.
6. Take measures to prevent reconnection of the energy sources.
7. Make sure that the machine is completely locked ... and that you have the right
machine.
After you have completed the work, restore operational readiness by performing the above
steps in the reverse order.
