Chapter 3 Wiring
In order to ensure the safety of operators and inverters, it is necessary to be operated by
qualified professional electricians. The following are special considerations when wiring
:
Make sure the input power is off before wiring.
The ground terminal of the inverter must be reliably grounded.
Verify that the rated voltage of the inverter matches the AC power supply
voltage.
The power cable must be connected to the R, S, and T terminals of the
inverter. The motor cable should be connected to the U, V, and W terminals.
Do not connect the fault. Otherwise, the inverter will be damaged internally.
Confirm that the terminals and wires are reliably connected, and the screws
of the main circuit terminals are secured.
Do not touch the main circuit terminals, otherwise there is danger of
electric shock.
