1.1 General safety instructions
Note
SINAMICS DCP is a member of the SINAMICS series of devices. This series of devices
mainly comprises components for electric drives. This is the reason that in these operating
instructions in chapters which are applicable for
several SINAMICS components (for
example PROFIBUS), the terms "Drive", "Master/leading drive", "Drive device" or "Drive
system" are used. In these Operating Instructions, "drive", "drive unit" or "drive system"
always refers to the SINAMICS DCP.
Electric shock and danger to life due to other energy sources
Touching live components can result in death or serious injury.
• Only work on electrical equipment if you are appropriately qualified.
• Always observe the country-specific safety rules for all work.
Generally, the following six steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any
of the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness by following the
above steps in the reverse order.
