Value = 21 Set output to PAC of installation. 55,000 W correspond to 5.50 V
* These values may overflow when the upper limit is reached.
The connector pin assignments are as follows:
X4, pin 1 Analogue output 1, 0 to 10 V
X4, pin 2 Analogue output 2, 0 to 10 V
X4, pin 14 Ground reference for analogue inputs
17.5 Digital inputs
The inverter is equipped with 2 voltage-free (isolated) digital inputs. Their level can be displayed by
means of parameters 35 and 36.
