shall be used. The shielding layer shall be connected to the grounding terminal PE of the inverter, and the

signal cable shall be no longer than 50m.



The wires of the control circuit terminals RA/RB/RC and other control circuit terminals shall be separately

routed.



It is forbidden to short circuit the shielding layer and other signal cables and the equipment.



When the inverter is connected to the inductive load equipment (e.g. electromagnetic contactor, relay and

solenoid valve), surge suppressor must be installed on the load equipment coil, as showed in Diagram 3-10
