1. a connection must be established between +24 and DI1 (clockwise rotation)

1. To achieve electromagnetic compatibility, the inverter must be operated with a built-in or external radio interference filter.

2. If shielded cables are used between the inverter and the motor, the shield must be connected to earth at both ends. Cable interruptions should be avoided if possible. If it is necessary to separate the cable, e.g. to install a motor contactor, the cable shielding must be connected through as directly as possible. It is important to ensure that the lowest possible HF impedance is achieved.

3. The shorter the cable, the lower the radio interference and leakage current. The maximum possible cable lengths must be taken into account.

4. To avoid interference with the control inputs, control cables should always be shielded. The shield must be connected to the cable clamp provided on the inverter. If the shield is also connected to a control device, care must be taken to ensure that the ground points have the same potential.

5. Control cables should not cross power cables if possible. Where this cannot be avoided, a right-angled crossing is recommended.

6. Separate laying of control and power cables should be aimed for. If the cables must be laid parallel, e.g. on the same cable route, the largest possible distance (> 20 cm) should be selected.

7. The shielding of the laid cables should have a low HF impedance if possible. Copper braiding is therefore preferable to steel braiding.

8. The RF contact resistance at the connection points between shielding and housing must be kept as low as possible. Dirt, paint and insulation residues on the housing and shielding in the area of the connections must therefore be removed. In principle, the cable clamps or crimp connections provided for this purpose should be used to connect the shielding. It is advantageous to use earthing cable glands.

9. The shielding should be connected to the housing as close as possible to the cable terminals. Longer, free cable ends act as antennas.

10. With unscreened cables, the cable wires should be twisted and output filters should be used.

In principle, it is possible to operate a motor with low power on a frequency inverter with higher power.
In this case, the ratio between motor and inverter power is important.
Experience shows that the ratio of 1:4 should not be exceeded.

E.g. it is not recommended to run a 0.75kW motor with a 30kW BLEMO frequency inverter.
For test purposes, this combination can be used, but the motor phase monitoring must be deactivated.
