After attempting to replace a hitachi inverter with an AcTech SF4100 i found it impossible to figure out wiring & parameters to set it up. It was fitted into a control panel which had a dial on the front for fan speed & stop/start switch. The stop/start switch had 2 wires & the dial for the fan speeds had 3 wires. I know its a long shot but has anyone attempted this before. Its the control wiring for fan speed and stop start thats the issue. The mains & 3 phase is not a problem. It is controling a large 3 phase fan used to extract fumes from a workshop area.
