2.6 Safety Considerations
1. Please use right wires according to relative laws. When the distance
between inverter and motor is over than 25meters, should raise wiring
standard.
2. Between the three-phase AC input power and main circuit terminal
(R,S,T) there must be a fuse switch. Make an electromagnetic contactor
in series to cut off power before the inverter steer its protection.
3. Ground terminal to the first grounded wiring.
The ground impedance must be less than 100R. Or make the ground
wire dimension is same with the main circuit wires.
