9.3. Additional Information for UL Compliance
BFI-E2 is designed to meet the UL requirements. In order to ensure full compliance, the following must be fully observed.

For an up to date list of UL compliant products, please refer to UL listing NMMS.E226333

The drive can be operated within an ambient temperature range as stated in section 9.1
 For IP20 units, installation is required in a pollution degree 1 environment

For IP66 (NEMA 4X) units, installation in a pollution degree 2 environment is permissible

UL Listed ring terminals / lugs must be used for all bus bar and grounding connections
Input Power Supply Requirements
Supply Voltage
200 – 240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed. 240 Volt RMS Maximum
380 – 480 Volts for 400 Volt rated units, + / - 10% variation allowed, Maximum 500 Volts RMS
Imbalance Maximum 3% voltage variation between phase – phase voltages allowed
All BFI-E2 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) Beijer Electronics recommends the installation of input line reactors.
Frequency 50 – 60Hz + / - 5% Variation
Short Circuit
Capacity Voltage Rating Min kW (HP) Max kW (HP) Maximum supply short-circuit current
115V 0.37 (0.5) 1.1 (1.5) 5kA rms (AC)
230V 0.37 (0.5) 4 (5) 5kA rms (AC)
400 / 460V 0.75 (1) 11 (15) 5kA rms (AC)
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.
Motor Cable 75°C Copper must be used
Fusing UL Class T Fuses must be used
Incoming power supply connection must be according to section 4.3
All BFI-E2 units are intended for indoor installation within controlled environments which meet the condition limits shown in section 9.1
Branch circuit protection must be installed according to the relevant national codes. Fuse ratings and types are shown in section 9.2
Suitable Power and motor cables should be selected according to the data shown in section 9.2
Power cable connections and tightening torques are shown in section 3.1
BFI-E2 provides motor overload protection in accordance with the National Electrical Code (US).

Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P-50 = 1
 Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information
shown in section 7.5
