Remark
1 You may either connect an external 24 V supply or use the internal 24 V supply.
3 … 6 The function of the digital inputs is shown in the factory setting.
You can change the function of the digital inputs subsequently.
The digital inputs are low-active in the factory setting. If you do not use one of the digital inputs, you must
connect the digital input with 24 V.
8, 11, 12 The function of the digital outputs cannot be changed.
8 The digital output signals a fully charged DC link of the converter. A charged DC link is the prerequisite for the
"operation" converter state.
11, 12 A device to protect against overload and short-circuit is required for the power supply to the line contactor
control, e.g. a 4 A / 250 V fuse.
Connect the excitation coil of the line contactor to a surge suppressor, e.g. an RC element.
