Installation
Determining the Cable Cross-section of the Input Lead (DC)
The following table shows the required cable cross-sections in relation to
the respective cable length. Select the cross-sections so that the voltage
drop to the G3 Combi is no more than 250 mV.
To avoid voltage dips, select a higher cable cross-section for
consumers with high starting currents (e.g. motors, compressors).
