8 BACK-UP
loads
• Connecting BACK-UP loads, such as loads requiring 24-hour power
supply or other important loads.
• Connecting unbalanced loads. L1, L2, L3 of the inverter respectively
connected to loads with dierent power.
• Loads with neutral wires are allowed when connecting three phase
loads to the BACK-UP port. Do not connect loads without neutral
wire to the BACK-UP port. Otherwise, the loads cannot work
properly or even be damaged.
• Do not connect auto-coupling or isolation transformers.
