*Remark
:
Long cable is easy to generate interference. It is recommended to use
shield cable.
3.5.3 Notes of control circuit wiring
●
Sperately arrange connecting wire of control circuit, connectin wire of main
circuit, other power wires or power line
●
To avoid malfunction caused by interference, you’d better use twisted shield
cable as connecting wire of control circuit. Wiring distance should be less than 20m.
●
One end of shield wire should be connected to the ground.
3.6 EMC guide
The inverter can generate a certain noise. To reduce or eliminate the noise, we
should correctly connect cables and wires, but also adopt the following meansures
according to actual situation on sites
:
3.6.1. Treating of conducted interference
(1) Set noise filter on the side of power supply can inhibit the noise generated by
the inverter power supply, and also inhibit the power supply noise effect on the
inverter. The inverter needs the special input noise filter.
(2) Isolate other equipments by using isolation transformers or power filters.
(3) Check whether external equipment and inverter wiring constitute closed loop.
3.6.2. Treating of radio-frequency interference (RFI)
(1) For easy-effecctive equipments and signal lines, please install far away from the
inverter.Use shield lines as singal lines.
Shield layer is connected to the ground, and cable of signal line is set into metal
tube.
