3.4.3 Transformer Fusing
The secondary of the transformer must have fuses installed in each of the legs. The
current for each fuse is:
Ampere = 0.8 transformer VA rating / RMS secondary voltage
If more than one drive is connected to the same secondary winding, each drive must
have it's own set of fuses as shown in Figure 3-6.
See Table 3-A for the recommended fuse size and type.
3.4.4 External Disconnect
The following two circuits are given as Emerson EMC recommended disconnect /
transformer / fusing examples.
