is equipped with a variable speed motor. Fig. 9 below shows a typical wiring diagram utilizing a Variable
Frequency Drive (adjusting the speed is possible). If it is not a requirement that the speed can be adjusted, a motor
starter should be installed in lieu of the VFD, if required by local codes.

RSIB 350-500 can operate at either 3x208-230 VAC or 3x440-480
VAC (default). The motor wiring terminals shown in Fig. 10 shows
default jumper positions for 3x440-480VAC operation.
If the application requires 3x208-240VAC operation, the jumper
positions must be changed according to Fig. 11.

After wiring, make sure the motor is rotating in the proper direction. This is marked on the motor end cover.
If the rotation is incorrect, swap the two wires going to the motor terminals, U1 and W1 as shown in paragraph 4.6 .
