OPTIONAL ACCESSORIES AND BOARDS
6. When an external keypad (HMI) is used (for further information, refer to the programming manual available for download on www.weg.net),
separate the cable that connects the keypad to the inverter from other cables of the installation, keeping a minimum distance of 10 cm
(4 in) between them.
11.2 FUNCTION EXPANSION BOARDS
The function expansion boards increase the MVC4 control board functions. There are 3 expansion boards available and their selection depends
on the application and the desired functions. The three boards cannot be used simultaneously. The difference between the EBA and EBB
boards is in the analog inputs/outputs. The EBC1 board serves for the encoder connection; however, it does not have its own power supply
as do the EBA/EBB boards. Next, the detailed description of those boards is presented
11.2.1 EBA (Expansion Board A - I/O)
The EBA board can be supplied in different configurations, created from the combination of specific functions.
The available configurations are shown in the table below.

NOTE!
The use of the RS-485 serial interface does not allow the use of the standard RS-232 input of the MVC4 board.
They cannot be used simultaneously.
