Line fusing
NRG Series drives have preinstalled line fuses. See the
Replacement Parts section for preinstalled line fuse size. When
replacing the line fuses, use fast acting fuses rated for 250 VAC
or higher, and approximately 150% of the armature current. Two
line fuses are required for models NRG02–D240AC–2Q and
NRG05–D240AC–2Q, while only one is required for model
NRG10–115AC–2Q. See Table 1 for recommended line fuse
sizes.
