the drive. Capacitors retain charge after power is removed.

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

installation and wiring have been properly followed.

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6months(duetostorage,

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 2 hours prior to actually operating the drive/motor system.

 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.

 DONOTconnectincomingACpowertooutputterminalsT1,T2,andT3!Donotcycleinput

power to the drive more than once every two minutes. Damage to the drive will result.

If the display does not appear, remove the incoming power, wait three minutes for the bus capacitors to

discharge, and verify correct installation and wiring. If the wiring is correct, re-apply incoming power and

note the display for drive status. If the display still does not appear call the factory for assistance. If the drive
