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.

A suitable fuse should be provided for DC

applications.

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.
