DO Connection
The inverter has two DO relays with different functions as follows:
DO1: Consumer load control. Please choose the appropriate contactor according
to the load power, e.g., the contactor types of the 3TF30 series from SIEMENS
(3TF30 01-0X). The relay is activated once the conditions of the control mode are
satisfied.
DO2: Earth fault alarm. Once the inverter receives the earth fault signal, the relay
closes the contact. The relay remains triggered until the fault is removed.
Cross-section: 1.0 mm², cable diameter: 3 mm–5.3 mm
