IEC Product Differentiators Conduit Boxes: The IEC standard location is on the top of the motor, with optional left side mounting indicated as F1 or right-side location indicated as F2. Terminal boxes can generally be rotated 4x90 degrees and terminal posts ensure easy lead connection. The NEMA standard location is on the left side of the motor, facing the output shaft is indicated as F1. A right-side location is indicated as F2, and on top of the motor as F0 or F3. Typically, IEC motors will have terminal blocks. Foot-mounted IM B3 IM 1001 Orientation: All references to an IEC configuration...

Connections: IEC motors typically use post- or stud-type terminal blocks, to connect the motor leads to the power leads. Wye Start/Delta Run connections are common in Europe and standard in the industry. In general, 7.5kW ratings and above are Wye/Delta. IEC Motor leads are marked U1, V1, W1 etc. NEMA motor leads are typically marked T1, T2, T3, etc. Foot- and flange-mounted with feet, large flange IM B35 IM 2001 IM V15 IM 2011 Mounting Codes: LEESON Passport Series IEC motors will be offered in foot-mounted B3, B3/B5, B3/B14 configurations, as well as vertical shaft-down mounted V5 and V1/V5...
