Line Filter installation:
Screw the line filter and the connecting wires together to the terminals as below.
The torque of 6 screws of the line filter is “2.5Nm”.
Please check that the screws connecting the line filter are not loose.
If the screw is loose, the screw will generate heats, and cause the line filter to breakdown.
Do not use an electric driver or an air driver, as this can cause damage to the line filter.
Connect the wires according to the wiring diagram.
