Input fusing and a power disconnect switch or contactor MUST be wired in series with terminals L1,

L2, and L3 (L1 and L2 if input issinglephase).IfonehasnotbeensuppliedbyLEESONElectric, a

disconnect means must be wired during installation. This disconnect must be used to power down or to

isolate the drive when servicing, or when the drive is not to be operated for a long period of time, but should

not be used to start and stop the motor. Repetitive cycling of a disconnect or input contactor (more than

once every two minutes) may cause damage to the drive.

10.1 WIRING FOR SINGLE PHASE OR THREE PHASE INPUT

If the drive is nameplated for 240/120 VAC single phase input, wire the input to terminals L1 and N and

jumperterminalsL1toL2for120Vacinputvoltage,orwiretoterminalsL1andL2(donotwiretoN)

for 240 Vac input voltage. Refer to Section 11.0 - MICRO SERIES POWER WIRING DIAGRAM.

If the drive is nameplated for three phase input only, wire the input to terminals L1, L2, and L3.

 Allthreepoweroutputwires,fromterminalsT1,T2,andT3tothemotor,mustbekepttightlybundled

and run in a separate conduit away from all other power and control wiring.

Do not install contactors between the drive and motor without consulting LEESON Electric for more

information.
