Motor connections
WARNING!
Never connect line power to the drive output terminals: U2, V2 or W2.
Line voltage applied to the output can result in permanent damage to the drive. If
frequent bypassing is required, use mechanically interlocked switches or contactors.
WARNING!
Do not connect any motor with a nominal voltage less than one half of
the drive’s nominal input voltage.
WARNING!
Disconnect the drive before conducting any voltage tolerance (Hi-Pot)
test or insulation resistance (Megger) test on the motor or motor cables. Do not
conduct these tests on the drive.
