Input AC Power Requirements

DANGER!
Hazard of electrical shock! Capacitors retain charge after power is removed. Before
servicing the drive, disconnect incoming power and wait until the voltage between
terminals B+ and B- is 0 VDC.
The input voltage must match the nameplate voltage rating of the drive. Voltage fluctuation must
not vary by greater than 10% overvoltage or 15% undervoltage.
NOTE
Drives with dual input voltage ratings must be programmed for the proper supply
voltage (refer to Parameter 01 - LINE VOLTAGE SELECTION in Section 4.4, Description
of Parameters).
The drive is suitable for use on a circuit capable of delivering not more than 5,000 RMS symmetrical
amperes at the drive's rated voltage.
If the kVA rating of the AC supply transformer is greater than 10 times the input kVA rating of the
drive(s), an isolation transformer or 2-3% input line reactor must be added to the line side of the
drive(s).
Three phase voltage imbalance must be less than 2.0% phase to phase. Excessive phase to phase
imbalance can cause severe damage to the drive.
Motor voltage should match line voltage in normal applications. The drive's maximum output voltage
will equal the input voltage. Use extreme caution when using a motor with a voltage rating which
is different from the input line voltage.

Input Voltage Ratings

SM000S Series drives are rated for 120 Vac single phase, 50-60 Hz input. The drive will function with
input voltage of 120 Vac (+10%, -15%) at 48 to 62 Hz.
SM200S & SL200S Series drives are rated for 208/240 Vac, single phase, 50-60 Hz input. The drive will
function with input voltage of 208 to 240 Vac (+10%, -15%), at 48 to 62 Hz.
SM200 Series drives are rated for 208/240 Vac, three phase, 50-60 Hz input. The drive will function
with input voltage of 208 to 240 Vac (+10%, -15%) at 48 to 62 Hz.
SM400 Series drives are rated for 400/480 Vac, three phase, 50-60 Hz input. The drive will function
with input voltage of 400 to 480 Vac (+10%, -15%) at 48 to 62 Hz.
NOTE
Parameter 01 - LINE VOLTAGE SELECTION must be programmed according to the applied
input voltage. Refer to Section 4.4, Description of Parameters.
