Troubleshooting
General The devices are equipped with an intelligent safety system. This means that to a large ex-
tent it has been possible to dispense with melting-type fuses. Melting-type fuses therefore
no longer need to be replaced. After a possible malfunction has been remedied, the device
is ready for use again.
