3.2.1 Input Voltage Ratings
SF200 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.
SF200Y 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.
SF400 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.
SF500 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 4.4 - Description of Parameters.
3.2.2 Input Fusing and Disconnect Requirements
A circuit breaker or a disconnect switch with fuses must be provided in accordance with the National
Electric Code (NEC) and all local codes. Refer to the following tables for proper fuse/circuit breaker
ratings and wire sizes.

WARNING!
Per UL requirements, use a fuse (not a circuit breaker) for 240 VAC drives requiring
>40A protection and for 480 VAC & 600 VAC drives requiring >32A protection.
Additionally, use a fuse (not a circuit breaker) for the following models:SF215Y,
SF220Y, SF230Y, SF250Y, SF250, SF275, SF575, SF5100, and SF5150.
