Input voltage ranges
Depending upon model and power rating, the drives are designed for direct connection to the following supplies:
Model Number
Supply Voltage
Phases
Frequency
BFI-H2-x2-xxxx-1xxx-xx
200 – 240 Volts + 10% / -15%

50 – 60Hz
BFI-H2-x2-xxxx-3xxx-xx
3
BFI-H2-x4-xxxx-3xxx-xx
380 – 480 Volts +10% / - 15%
3
All drive units have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping. For input supplies which have
supply imbalance greater than 3% (typically the Indian sub- continent & parts of Asia Pacific including China) The Manufacturer recommends
the installation of input line reactors. Alternatively, the drives can be operated as a single phase supply drive with 50% de-rating.

All the drives in the above table are suitable for use on a circuit capable of delivering not more than the above specified maximum short-
circuit Amperes symmetrical with the specified maximum supply voltage.
For more details about the drive power rating/size information, please refer to the latest drive brochure.

Output Power and Current ratings
The following tables provide the output current rating information for the various drive models. The Manufacturer always recommends that
selection of the correct drive is based upon the motor full load

Note
The maximum motor cable length stated applies to using a shielded motor cable. When using an unshielded cable, the maximum cable length
limit may be increased by 50%. When using the Invertek Drives recommended output choke, the maximum cable length may be increased by
100%
The PWM output switching from any inverter when used with a long motor cable length can cause an increase in the voltage at the motor
terminals, depending on the motor cable length and inductance. The rise time and peak voltage can affect the service life of the motor.
Invertek Drives recommend using an output choke for motor cable lengths of 50m or more to ensure good motor service life
For UL compliant installation, use Copper wire with a minimum insulation temperature rating of 70°C, UL Class CC or Class J Fuses
