Instruction of NZ2000 Series Inverter
(2)Moulded case circuit broaker:(MCCB)
When the power supply voltage is low or the input terminal
short circuit occurs,the breaker can provide protection,during
inspection,maintenance or the inverter is not running,you can cut off
the breakerto separate the inverterfrom the power supply.
(3)Magnetic contractor{MC)
The contractor can tum on and tum offthe power
of the inverter to
ensure safety.
(4)AC current reactor
a suppress high harmonicto protect the inverter to ensure safety.
(5)Brake resistor
When the motor is braking, the resistor can avoid DC bus high
voltage of the inverter ,and improve the braking ability of the internal
brake
unit
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 1000
(6)Use the shortest earth cable possible.
(?)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 em awayfrom
the paral!elled control cables, when the power cables and 1he control
cables are crossed,make them verticai.Don't make the power cables
and the control cables together,
or the interference will cause.
(9}Under nonnal circumstances,the diatance 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 selectthe output
side filter,and reduce the carrierfrequency.
(10)Don't install an absorbing capacitor or other capacitance-
resistance absorbing devices.

Chapter2 Installation and wiring
(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,causesparks and the shortcircuit
To minimize the interference,it is recommended that the contactor
and relayshould be connected
to the surge absorber.
• Noisefilter installed at the input side of inverter;
• Install noise isolation for other equipment by means of isolation
transformer or powerfilter.
