RECOMMENDATIONS FOR CONNECTION VIA RS-485
When connecting the Drive Scan to any WEG device via serial (RS-485), terminations must be provided at the
external connection points. In cases where both ends are arranged on the CFW, SSW or MVW lines, their interfaces
already have switches to enable the termination resistors.

In case the ED300 is at an end, it is recommended to use an external termination module, such as those listed
below:
PSB-TERMINATOR-PB-TBUS (Phoenix Contact);
6ES7972-6DA00-0AA0 (Siemens);
AT303 (Smar)
