Supply Voltage .
230 V a.c.
AO - Analogue output, 4 pcs. AO1 - AO4
Must be used when using a frequency converter or EC motors.
Connect 24 V on N and L. Avoid earth fault current. Use
double-insulated transformer. The secondary side must
not be earthed.
Obtain 0-10 volts from terminals N and AO1, respectively N and
AO2. PAY ATTENTION TO THE POLARITY of N.
Modbus
It is important that the installation of the data communication
cable be done correctly. Cf. separate literature No. RC8AC.
Remember termination at the bus termination.
Termination
(Only if an external display is connected)
Insert a jumper between the two connections on the left
(R120-CANH).
Warning
The supply voltage of AI may not share
the signal with other controllers.
