Input Fuses
All drives must have input fuses installed in the power supply to the
drive. These fuses may be specified as an option to the drive and
supplied by Danfoss Graham. If specified, they will be installed by
Danfoss Graham in an enclosure external to the drive which may
include other optional features. If not supplied by Danfoss Graham,
they must be supplied by the installer of the drive at the time of
installation.
The required type of fuse for each drive size is shown in the table
below. The fuse rating shown is both the maximum and the recom-
mended fuse rating.
The drives are suitable for use on circuits capable of delivering not
more than 100,000 RMS symmetrical amps, 500 volts maximum (600
volts maximum for 575 volt drives), when used with the recommended
fuses.
