4.3.2   Typical Power Connections

See Section 4.2 starting on page 25 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 appli-

cable electrical codes. The Vacon 50X 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), CEC (Ca-

nadian Electric Code) and local requirements. All fuse ratings included in Table 8 below are for reference 

only and do not supersede code requirements. For 230/400 V mains supplies we recommend time-lag 

type NEOZED-fuses. The recommended supplier is Bussman.
