7 INPUT AC POWER REQUIREMENTS

DANGER!

Hazard of electrical shock! Capacitors retain charge after they've been

removed. Disconnect incoming power and wait until the voltage between

terminals B+ and B- is 0 VDC before servicing the drive.

The input voltage must match the nameplate voltage rating of the drive. Voltage ﬂuctuation

must not vary by greater than 10% over voltage or 15% under voltage.

NOTE

Drives with dual input voltage ratings must be programmed for the proper

supply voltage (refer to Parameter 01 - LINE VOLTAGE SELECTION in

Section 15 - DESCRIPTION OF PARAMETERS).

The drive is suitable for use on a circuit capable of delivering not more than 5,000 RMS

symmetrical amperes at 5 HP (4.0 kW) and below, and 18,000 RMS symmetrical amperes at

7.5 - 10 HP (5.5 - 7.5 kW), 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’s power components.

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.

7.1 INPUT VOLTAGE RATINGS

TF200 Series drives are rated for 208/240 Vac, three phase, 50-60 Hz input. The drive will

function with input voltages of 208 to 240 Vac (+10%, -15%) at 48 to 62 Hz.

TF200Y Series drives are rated for 208/240 Vac, single or 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.

TF400 Series drives are rated for 400/480 Vac three phase, 50-60 Hz input. The drive will

function with input voltages of 400 to 480 Vac (+10%, -15%) at 48 to 62 Hz.

TF500 Series drives are rated for 480/590 Vac, three phase, 50-60 Hz input, and will function

with input voltages of 480 to 590 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 15 - DESCRIPTION

OF PARAMETERS.
