Terminal strip X9
Terminal strip X9 is used to connect an external 24 VDC power supply and to connect a
main or bypass contactor.
Fault and alarm signals can be connected to the digital inputs. The digital output allows, for
example, an external rectifier to be controlled.
The external 24 VDC power supply must be connected if the inverter is connected to the line
supply via a main contactor (to start the Control Unit).
The power supply should be located directly next to the inverter (e.g. in the same cabinet).
The cable length to terminal X9 must not exceed 30 m.
