Procedure:
1. Switch-off the control: Completely switch off the system. Check that the system is in a no-
voltage condition and is locked-out so that it cannot be switched on again without the
appropriate authorization.
2. Access the operator panel/control cabinet in which the machine control panel is located.
3. Using a multimeter, check the X10 power supply to ensure that the system really is in a
no-voltage condition.
4. If it has not already been done, label all connectors that lead to the module now.
Only then, can it be ensured that the cables are not interchanged.
5. Withdraw the power supply X10 (
