interference of the frequency inverter output side to the other equipment,
you have better to install a special noise filter at the output side of
the frequency inverter and lay the output cables through the metal tubes.
8. If the frequency inverter need to frequently start, do not cut off the
power, you should operate it through the control terminals (COM / FWD.
REV) or keyboard.
9. As analog signals are very easily to be interfered, isolation device
or shield lines are needed for the external control wires of the
inverter and the ground terminals of shield lines are needed to be
connected to the metal closet(ground terminals) of the inverter.
10. Control cables、power cables should be separated from the motor cables.
Generally there should be a sufficient distance between them,
especially between the parallel cables that extend for long distance;
When signal cables have to pass through the power cables, they should
be orthogonal crossing.
11. Main circuit wiring and wire diameter specifications have to be in
accordance with national laws.
12. Pls switch motor or switch power after inverter stop output.
13. While dismantle or change motor, you must cut off the input power of
inverter.
14. In order to avoid accidents, ground terminal E or 〨 must be reliable
grounding (grounding impedance should below 10 Ω). Otherwise there is
a risk of leakage current. For frequency inverter ground point, you
should best adopt the special ground pole. You can also use the share
ground pole, but never use tandem ground line.
15.Pls do not change three phase frequency inverter input into two phase.
Otherwise there may be malfunction. If you have only two-phase power,
please choose single-phase power frequency inverter.
16.The frequency inverter can't be used in the occasions where voltage of
