Protecting the Primary Side
The device must be installed according to the
speci ? cations of EN 60 950. It must be possible to
switch off the device using a suitable disconnecting
device outside the power supply. For example, primary
side line protection could be used.
Three external thermomagnetic fuses are required to
protect the device. Even in the event of a phase failure,
continuous operation is ensured with nominal power.
Recommended Fuse:
3 x circuit breaker 6 A, 10 A or 16 A, Characteristic B
(or equivalent). A suitable fuse must be ? tted for DC
applications.
If an external fuse is blown, this is most
probably due to a device fault.
In this case, the device should be
checked in the factory.
