The Allen-Bradley/Rockwell Automation 1336F-BRF75-AN-EN-L4 is a 480 Volts AC variable frequency drive. The drive accommodates digital outputs on Terminal Block 2 and digital inputs on Terminal Block 3. Note that when a 2-wire control on Terminal Block 3 is used to automatically restart the 1336F-BRF75-AN-EN-L4 drive, there is a risk of injury for the users. This is because a 2-wire control uses maintained run contacts that act as both closed devices and as open devices. Stopping the drive through the stop contact and rerunning the drive by closing the terminal will reset any fault on the drive. Care should be taken when clearing a fault this way since if there was a valid start command, the 1336F-BRF75-AN-EN-L4 will automatically restart.

The Allen-Bradley/Rockwell Automation 1336F-BRF75-AN-EN-L4 is programmed to be able to fit a particular application by way of its parameters. The parameters can be viewed and changed by using a human-machine interface module which can either be installed on a dedicated slot on the 1336F-BRF75-AN-EN-L4 or it can be interfaced with the drive through the terminal block. The difference between these 2 human-machine interface modules is that the onboard module is not removable when the drive is running while the one that is interfaced through the terminal block can be connected and disconnected without stopping the 1336F-BRF75-AN-EN-L4 first. Additionally, the drive will fault when an onboard human-machine interface module is removed when the drive is running. The 1336F-BRF75-AN-EN-L4 supports a TTL contact on its control interface, it is supplied with an English manual, and it is designed to be mounted in an enclosure with an IP00 rating.
