Fuse sizes, inverters
Each DC supply line must be equipped with an aR fuse according to the table below.
The fuse sizing in the tables below is based on Bussman aR fuses. We recommend you to use these fuses.
Sufficient protection against short-circuit cannot be guaranteed if other fuse types are used. Furthermore,
equation of the fuse values given in the tables below with those of other fuse manufacturers is not
allowed. In case you wish to use fuses of other fuse manufacturers, contact Vacon.
