Connecting an AC output power cable (1) (unit: mm) Figure 5-4 Step 3 Insert AC output cable (L, N, PE) into the cable gland and the adapter, as shown in Figure 5-6. Connecting an AC output power cable (2) Figure 5-5 Step 4 Loosen the screws inside the coupling nut holes using a screwdriver, insert the core wires into corresponding holes, and tighten the screws, as shown in Figure 5-6.
5.4 Connecting DC Input Power Cables Before connecting the DC input cable, please make sure that the Inverter “DC SWITCH” in the “OFF” status, otherwise, the high voltage can bring about life threatening. Table 5-2 Recommended DC input cable specifications Conductor cross-section(mm2)...
1. Bayonet 5.5 Disconnect the electrical connections Step 1 Disconnect the circuit breaker between the inverter and the grid. Step 2 Ensure that the DC SWITCH is OFF. Step 3 Disconnect the RS485 communication cable. Step 4 Disconnect the DC input cable. Step 5 Disconnect the AC input cable.
6. SYSTEM OPERATION 6.1 Operating mode SF series has three working mode: standby mode, operating mode, off mode. 6.2 Powering on the SF series After ensure that electrical connections have been completed correctly, run the operation of power-on, then turn on the inverter. Step 1Check that the SF series is installed on the wall correctly and securely.
