WARNING! Electrical Shock Hazard. Do not touch any terminals before the

capacitors have fully discharged. Failure to comply could result in death or serious

injury. Before servicing, disconnect all power to the equipment. The internal

capacitor remains charged even after the power supply is turned off. The charge

indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent

electric shock, wait for at least the time specified on the warning label, once all

indicators are OFF, measure for unsafe voltages to confirm the drive is safe prior

to servicing.

Switch the wires for T1 and T2 on the output terminals of the motor overload relay. Re-

tighten the terminal lugs and reapply power.

5. Reapply the power, press

HAND

and re-check the rotation direction.

6. Verify that the system is ready to operate at full speed by making sure that the building

automation system logic is ready for the start, stop, and speed command functions.

7.

Press

to increase the frequency reference in increments of 10 Hz, verifying smooth

operation at all speeds. For each frequency, check the drive output current using monitor

U1-03. The current should be well below the motor rated current.
