Main circuit diagram
The DC/DC converter module must be equipped with external DC fuses. You can equip the
converter with a DC switch/disconnector, if quick isolation of the module from the DC bus
is required.
This figure shows a simplified main circuit diagram of a DC/DC converter without a DC
switch/disconnector and charging circuit.
