Installation and Connection
NOTE!
To be able to use the analog input and/or output as current signals, it is
necessary to change the switch S1 and the related parameters as per table
3.1. In order to set the analog inputs to bipolar voltage signal (-10...10V), it is
necessary to set P0233 and P0238 according to table 3.1. Refer to the CFW700
Programming and Troubleshooting manual for more information.

NOTE!
Settings of the S2 switch:
S2.1 = ON and S2.2 = ON: RS485 is ON.
S2.1 = OFF and S2.2 = OFF: RS485 is OFF.
The factory default for the S2.1 and S2.2 switches are OFF.
Other combinations of switch S2 are not allowed.
