12 INITIAL POWER UP AND MOTOR ROTATION

DANGER!

Hazard of electrical shock!

Capacitors retain charge after power is removed. Disconnect incoming

power and wait until the voltage between terminals B+ and B- is 0 VDC

before servicing the drive.

STOP!

• Do NOT connect incoming AC power to output terminals T1, T2, and

T3! Severe damage to the drive will result.

• Do NOT continuously cycle input power to the drive more than once

every two minutes. Damage to the drive will result.

• Severe damage to the drive can result if it is operated after a long period

of storage or inactivity without reforming the DC bus capacitors!

If input power has not been applied to the drive for a period of time exceeding three years

(due to storage, etc), the electrolytic DC bus capacitors within the drive can change internally,

resulting in excessive leakage current. This can result in premature failure of the capacitors

if the drive is operated after such a long period of inactivity or storage.

In order to reform the capacitors and prepare the drive for operation after a long period of

inactivity, apply input power to the drive for 8 hours prior to actually operating the motor.

Before attempting to operate the drive, motor, and driven equipment, be sure all procedures

pertaining to installation and wiring have been properly followed.

Disconnect the driven load from the motor. Verify that the drive input terminals (L1, L2, and

L3) are wired to the proper input voltage per the nameplate rating of the drive.

Energize the incoming power line. The LED display will sequence through displays that show

the drive's parameter version (500 in the example below), HP rating, and voltage rating. It

should then read “- - -”, which indicates that the drive is in a STOP condition. The following

diagram illustrates the initial LED display sequence.
