CHAPTER 3 - INSTALLATION AND CONNECTION
The signal connections (analog inputs/outputs) and control
connections (digital inputs and relay outputs) are made on
the XC1 connector of control board (refer to the location in
figure 3.5, item 3.2.2).
There are two configurations for the control board: standard
version (CFW-08 line) and Plus version (CFW-08 Plus line),
as shown below:
