Note:
Thermal fuses
Instead of conventional melting fuses the TwinBus power supply unit 1 7573 has two electronic fuses
that interrupt the respective power circuit if an overload occurs. If one of these fuses activates, the
associated voltage indicator LED goes off. Proceed as follows to switch on again:
Switch mains voltage off and leave off for approximately 1 minute.
Remedy short circuit or overload.
Switch mains power supply on again.
The associated voltage indicator LED illuminates again.
* Cut off the cover for connecting to additional devices.
