Step 5 - Wire AC Power to the Unit

and Ground the Unit

Observe the following guidelines when wiring AC power:

• The terminal block accepts up to 3.31 mm

2

(12 AWG) wire.

• The recommended tightening torque is 1.3 newton-meters (12 in-lb).

• Verify that the input power to the unit corresponds to the unit voltage and frequency

and that the input supply is of sufficient capacity to support the input current
requirements. Refer to Appendix A, Technical Specifications.

• Size the AC line conductors for the unit rating and in accordance with all applicable

local, national, and international codes.

Use the following procedure to wire AC power to the unit. Grounding instructions are
provided in Section 5.1.

Remove the cover by loosening the four cover screws. Note that the keypad/display
ribbon cable is designed to disconnect from the main unit when the cover is removed
as shown in Figure 5.1.

Removing the Cover

ATTENTION: If the distribution system capacity exceeds the unit’s
maximum symmetrical fault short-circuit current of 10,000 amps,
additional impedance should be added to the AC line supplying the unit
to limit available current in the event of a fault. Failure to observe this
precaution could result in severe bodily injury or loss of life.

ATTENTION: The drive is intended to be commanded by control input
signals that will start and stop the motor. A device that routinely
disconnects then reapplies input power to the drive for the purpose of
starting and stopping the motor should not be used. If it is necessary to
use this method for starting and stopping, or if frequent cycling of power
is unavoidable, make sure that it does not occur more than once a minute.
