Technical data of the control cable terminals

Red pins avoid mixing up the connectors. The control cable terminals are plug-in
connections. You can unplug the plugged-in connections when disconnected from the power
supply.
When installing cables and selecting the cabling materials, it is essential that you observe
the information in sections "Safe isolation in accordance with EN 61800-5-1" (Page 145) and
"Connecting the control cable" (Page 93).
The control cable terminals are color-coded:
● The green terminals on the far left contain all relay outputs and the optocoupler inputs at
a separate potential.
● The black terminals contain the potential-free analog inputs and digital inputs which are
electrically separated the same as the analog inputs.
● The white terminals contain the electrically separated analog outputs.
All external voltages can be connected together for controlling a PCS or PLC. To do this,
jumper the ground terminals -X2:1 with -X2:51 and -X2:51 with -X2:71.
If you control the converter using different devices, potential displacements occur which
depend on the cable length used. Remove the jumpers for longer cables.
