Removing
Procedure:
1. Switch off the complete system, carefully checked that it is in a no-voltage condition and
lock it out so that it cannot be switched on without the appropriate authorization.
2. Access the control cabinet where the CU310-2 PN is located.
3. Use a multimeter to check that the CU310-2 PN really is in a no-voltage condition.
4. If it has not already been done, label all connectors and cables that lead to the module now.
Only then, can it be ensured that the cables are not interchanged.
5. Withdraw the electronics power supply X124.
6. Withdraw the DRIVE-CLiQ cable X100.
7. Withdraw all other cables, if available.
