Note:
1, Parameters in the table are recommended values.
2, The input protection fuses of inverters EV2000-4T0185G1/
0220P1 and EV2000-4T0220G1/ 0300P1 are respectively the
RT16 Series 63A and 80A products of Xi'an Fusegear
Manufacture Company.
4). DC reactor
DC reactor is required for the drive whose power is
greater than EV2000-4T0750G, for the drive whose
power is lower than EV2000-4T0750P, it is optional.
Under following conditions, a DC reactor should be used
to reduce the impact of AC supply to the drive and to
protect the drive and suppress the high-order harmonics.
(1) If a capacitor tank used for reactive power
compensation or a SCR load shares the same AC supply
with the drive, the harmonics caused by the SCR load or
the capacitor tank when it is switched on or off may
damage the drive’s input rectifying circuit;
(2) When the unbalance rate of 3-phase AC supply of the
drive is greater than 3%;
(3) If the input power factor of the drive is required to be
greater than 0.93;
(4) When a large capacity transformer is connected to the
drive, the input current of the drive may damage the
rectifying circuit. Generally, if the input AC supply
capacity of the drive is above 550KVA, or if the input AC
supply capacity is 10 times that of the drive, a DC reactor
is required to connect to the drive.
(5) Input AC Line Reactor
A line reactor should be used if the distortion of power
network is severe or the input current harmonic level is
high even after a DC reactor has been connected to the
drive. It can also be used to improve the AC input power
factor of the drive.
6) Output AC Line Reactor
When the cables from the drive to motor are longer than
80m, multi-stranded cables and an AC line reactor should
be used to suppress the high frequency harmonics. Thus,
the motor insulation is protected against heat due to
harmonics, leakage current is reduced and the drive will
not trip frequently.
(7) Input EMI filter
An EMI filter can be used to suppress the high frequency
noise generated by the drive’s power cables.
(8) Output EMI filter
An EMI filter can be used to suppress the drive’s output
noise and leakage current of cables.
(9) Safety ground
Since there is leakage current inside the drive, to ensue
safety, both the drive and the motor should be grounded,
the grounding resistance should be less than 10
Ω
. The
ground wire should be as short as possible. Please refer
to the section of the earth wire in Table 3-2.

Note that the data in the above table apply when the
conductor connected with the ground wire are made of
the same metal, otherwise, please calculate the
equivalent section based on the conductivity.
Notes:
1. EV2000 drive can meet the requirements of IEC 61800-3
after EMI filter is installed.
2. Installation of input and output EMI filters must be as close
to the drive as possible. Refer to Section 3.4 of Chapter 3 for
EMC installation instructions.
3. Refer to Section 2.3 of Chapter 2 and Appendix 2 for the
technical parameters of optional parts.
