The 1336F-BRF50-AA-EN-HAS1 is a PLUS II Adjustable Frequency AC Drive produced by Allen Bradley. It runs in the voltage range of 380 to 480 Volts AC or 513 to 620 Volts DC and has a voltage rating of 3.7 kW, as well as a horsepower rating of 5 HP. It can be fitted with an IP20 enclosure and has an English language interface; it also features a Programmer/Controller Human-Module Interface with an Analog Port. The 1336F-BRF50-AA-EN-HAS1, just like other All PLUS II Adjustable Frequency AC Drives, has a start/stop control circuitry with solid-state parts. An additional hardwired stop circuit is needed to disconnect the AC line power supplying the drive. Once you remove the AC power, there is an inherent regenerative braking effect and the motor will come slowly to a stop. There are instances when an auxiliary braking solution is required.

Input signals control when the 1336F-BRF50-AA-EN-HAS1 will stop and start the motor. It is not compatible with a controller that regularly disconnects and reapplies line power to the drive to stop and start the motor. One should be careful when applying or installing a bypass system since incorrect installation can lead to reduced product life or damaged components. Some of the common causes of damage include wiring the AC line to the 1336F-BRF50-AA-EN-HAS1 control terminals or output; output circuits not connected directly to the motor; or improper output or bypass circuits not certified by Allen Bradley. The 1336F-BRF50-AA-EN-HAS1 has immunity to generated electrical interferences. There’s no need to observe special precautions aside from the usual installation practices. Coils of DC energized contactors linked with the 1336F-BRF50-AA-EN-HAS1 should be suppressed with a diode to avoid electrical transients.
