6. For normal operation, make sure drive output terminals U/T1, V/T2 and W/T3 are
connected to motor terminals U, V and W (respectively). The motor will rotate
counterclockwise as viewed from the shaft ends of the motor when a forward operation
command is received. To reverse the direction of motor rotation, switch any two of the
motor leads.
7. Make sure the power source is capable of supplying the correct voltage and required
current to the drive.
8. Do not attach or remove wiring when power is applied to the drive.
9. Do not monitor the signals on the circuit board while the drive is in operation.
10. Route the power and control wires separately or at right angles to each other.
11. If required to reduce electro-magnetic interference (EMI), install the filter as close as
possible to the U/T1, V/T2 or W/T3 side of the drive.
Note: Do not use a capacitor or L-C filter (inductance/capacitance) or an R-C filter
(resistance/capacitance).
12. When using a GFCI (ground fault circuit interrupt), select a current sensor with a
minimum current of 200 mA and a minimum detection time of .1 second to avoid
nuisance tripping.
