Stator Wiring
The locked rotor stator current is equal to the amplifiers continuous rating and for either low
speed or locked rotor conditions the stator must withstand this continuous rating. Derating the
stator wiring for three phase operation should not be done.

For operation at 460 Vac it is recommended that the stator wiring insulation withstand 600
volts.
A
(ground) terminal is supplied and should be connected to earth ground.
If shielded cable is not used, it is recommended that the RST and GND wires be twisted.
