9.0 VOLTAGE SELECTION
9.1 INPUT VOLTAGE RATINGS
115/230 Volt MICRO Series drives are rated for 240/120 Vac, 50-60 Hz input. The drive will function
with input voltage of 120 Vac (+10%, -15%) at 48 to 62 Hz when wired for 120 Vac input, or with input
voltage of 240 Vac (+10%, - 15%), at 48 to 62 Hz, when wired for 240 Vac input.
230 Volt MICRO Series drives are rated for 240/200 Vac, 50-60 Hz input. The drive will function with
input voltages of 200 to 240 Vac (+10%, -15%), at 48 to 62 Hz.
460 Volt MICRO Series drives are rated for 480/400 Vac, 50-60 Hz input. The drive will function with
input voltages of 400 to 480 Vac (+10%, -15%), at 48 to 62 Hz.
575 Volt MICRO Series drives are rated for 590/480 Vac, 50-60 Hz input. The drive will function with
input voltages of 480 to 590 Vac (+10%, -15%), at 48 to 62 Hz.
NOTE: Parameter 0 - LINE VOLTS must be programmed according to the applied input voltage . See
Section 18 .0 - DESCRIPTION OF PARAMETERS .
10.0 POWER WIRING
Hazard of electrical shock. Disconnect incoming power and wait three minutes before servicing
the drive . Capacitors retain charge after power is removed .
Note drive input and output current ratings and check applicable electrical codes for required wire type and
size, grounding requirements, over-current protection, and incoming power disconnect, before wiring the
drive. Size conservatively to minimize voltage drop.
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 .
