This enclosure has air vents and a communications access door that leads to the RS-232 9-pin female port located on the regulator PCB for easy access rather than removing the entire cover.
The 20V4140 has many a variety of internal components. It has an internal and external fan assembly, gate driver PCB, power supply PCB, power PCB, regulator PCB, capacitor PCB, current feedback PCB, and a built-in keypad with a mounting bracket for the regulator board. The regulator can be positioned within its mounting bracket so that its 7-segment LED display can be seen on the keypad, and its RS-232 port can be accessed through the access door on the drive’s faceplate.
The best manual to use when operating and installing the 20V4140 model is the D2-3324-1 Instruction Manual. The D2-3324-1 manual is vital as it lists all of the hardware within the model, installation procedures, and how it can work in tandem with other models within the GV3000 series.
