2.6.4 Connecting the Temperature Sensor
It is recommended that the PT1000 is connected to the inverter to sample the
temperature of the lead-acid battery or the external environment of the battery.
The temperature sensor is located next to the lead-acid battery.
Cross-section: 1.0 mm², cable diameter: 3 mm–5.3 mm
2.7 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.
