Typical Power Connections
Diagram 5 shows the terminal connections for line power and motor output. See Step 8 for input
line requirements.
Note that when testing for a ground fault, do not short any motor lead (T1/U, T2/V or T3/W) back
to an input phase (L1/R, L2/S or L3/T).
As shown in Diagram 5, it is necessary to provide fuses and a disconnect switch for the input AC
line in accordance with all applicable electrical codes. The drive is able to withstand a 110% over
load for 60 s. For maximum protection of the drive, use the fuses listed in Tables 9, 10 and 11
found below and on the next page. The recommended supplier is Bussman.
