Motor Cable Length
Maximum motor cable length is 164 ft (50 m). Motor
cable length is given to ensure performance of only
the SED2, not the suitability of the motor when
connected to a SED2 at this distance. See Figure 8
for motor cable installation notes.
Motor Connection
The motor nameplate indicates the required supply
voltage and method of connection (delta, Δ, or
star/wye, ‘Y’, configuration). Connect motor wiring to
SED2 terminals U, V, and W. See Figure 9.
