2.3.3 Precautions main circuit wiring
(1) circuit wiring ,refer to requirements of electrical codes.
(2) Application of supply power to output terminals(U,V,W)of the invert will damage it, so never perform such wiring.
(3) Power supply's wiring ,please use isolated wire and wire pipe if possible, and make isolated wire and wire pipe link to the earth.
(4) The inverter and welding device, high-power motor, high-power load can't use a earth cable.
(5) The ground terminal E, ground impedance is lower than 100Ω (6) Use the shortest earth cable possible.
(7) Many inverters are earthed, pay attention not to cause ground loops.
(8) the power cables and the control cables must be separated in the main circuit. keep the power cables more than 10 cm away
from the paralleled control cables, when the power cables and the control cables are crossed, make them vertical. Don't make the
power cables and the control cables together, or the interference will cause.
(9) Under normal circumstances, the distance between the inverters and the motors is less than 30m, the current produced by
the parasitic capacitance may cause over-current protection, mis action, inverter's fault and equipment operating faults .The
maximum distance is 100m, when the distance is long, please select the output side filter, and reduce the carrier frequency.
(10) Don't install an absorbing capacit
or or other capacitance resistance absorbing devices.
(11) Ensure the terminals are all locked tightly, the cables are connected well with the terminals, present the looseness due to an
action of shaking, cause sparks and the short circuit
To minimize the interference.it is recommended that the contactor and relay should be connected to the surge absorber.
•
Noise filter installed at the input side of inverter;
•
Install noise isolation for other equipment by means of isolation transformer or power filter.
