44 Planning the electrical installation
Inverters without input DC fuses (option +0F291)
If the standard input DC fuses are not suitable for the customer application, the inverter
can be delivered without input DC fuses (option +0F291). In this case, install appropriate
DC fuses to protect the inverter DC circuit and the DC input cables in a short-circuit
situation. Protect the positive and negative poles of an input with separate fuses. The
power loss of a fuse may never exceed 25 W.
For the recommended DC input fuse options, refer to DC input fuse recommendations on
page 50.
