z
The cable connected to the control terminal should leave away from the main
circuit and heavy current circuits (including power supply cable, motor cable, relay
and contactor connecting cable) at least 20cm and parallel wiring should be avoided.
It is suggested to apply perpendicular wiring to prevent inverter malfunction caused
by external interference.

4.6.3 Jumpers on control board
Jumper
Function
J2, J4
Default setting: J2 and J4 are disconnected. It is prohibited to be
connected together, otherwise it will cause inverter malfunction.
J7
Default setting: 2 and 3 connected. Do not change default setting
otherwise it will cause communication malfunction.
