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.
