Power
：
●Use the power supply in the permissible specifications of the inverter model to
avoid damaging the drive.
No fuse circuit breaker(MCCB)
：
● A non-fuse circuit breaker (MCCB) must be installed between the AC power
supply and the inverter, but do not use it as inverter's operation / stop switching
function.
● Use a non-fuse circuit breaker (MCCB) that complies with the rated voltage
and current rating of the inverter. When the capacity is selected, it is at least 2
times the sum of the rated output current of the inverter (mainly considering
150% of the inverter overload,1min).
Leakage circuit breaker(RCD/ELCB)
：
● Please install the leakage circuit breaker, to prevent leakage caused by the
malfunction and to protect the safety of the use of personnel;
● Each inverter should use a dedicated circuit breaker whose sensitive current is
more than 30mA;
● When using an ordinary circuit breaker, the current sensitivity must be more
than 200mA, operation Time must be more than 0.1s.
Electromagnetic contactor
：
● Normally, there is no need to add electromagnetic contactor, but it can be used
as an external control protection, automatic restart after power failure and other
functions
，
must install electromagnetic contactor.
● When using the brake unit, please connect to the thermal relay contact of the
brake unit, close the electromagnetic contactor when overheating;
● Do not use the electromagnetic contactor as the inverter's operation / stop
switching function, which will shorten the life of the inverter.
Power Improvement AC Reactor
：
●If a large capacity (500KVA or more) is used for the inverter, an excessive peak
current may flow into the input side of the inverter, and the rectifier element may
be damaged. In this case, the AC reactor can also improve the power factor on
the power supply side.
Input side noise filter
：
● It is possible to remove the noise from the power supply line into the inverter
and to reduce the noise from the inverter to the power supply line.
● When there is an inductive load around the inverter, please ensure to install it.
Inverter
：
●Input power terminals R / L1, S / L2, T / L3 are connected without any phase
sequence.
●The output terminals U / T1, V / T2, W / T3 are connected to the U / T1, V / T2,
W / T3 terminals of the motor. If the inverter is running forward, the motor is
reversed. / T2, W / T3 terminal in any two can be adjusted.
●Do not connect output terminals U, V, W to AC power to avoid damage to the
inverter.
●Ground terminal should be properly grounded, 220V level: grounding
resistance should be below 100
Ω
, 440V class: grounding resistance should
be10
Ω
or less.
Zero phase filter
：
● When you want to reduce the electromagnetic interference caused by
the inverter, it is effective in the range of 1MHz ~ 10MHz. The more the
number of the motor wires are bypassed, the better.
Install as close to the inverter as possible,suitable for either the input side or
output side of the inverter.
