See Section 4.3 starting on page 31 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).
It is necessary to provide fuses and a disconnect switch for the input AC line in accordance with all
applicable electrical codes. The X5 AC drive is able to withstand a 150% overload for 60 seconds
for heavy duty rating, and 120% overload for normal duty rating.
The fusing and input protection of the drive must always meet UL, NEC (National Electric Code),
and CEC (Canadian Electric Code) requirements. All fuse ratings included in Table 4-6 below are
for reference only and do not supersede code requirements. The recommended supplier is Bussman.
