FUSE/ NFB
There may be an inrush
Fuse/NFB current during power up.
Magnetic contactor
Please refer to 3.7.1 and
select the correct fuse /NFB.
Please do not use a Magnetic
Input AC Line Reactor
Magnetic contactor as the I/O switch of
contactor the inverter, as it will reduce
the operating life cycle of the
inverter.
AC line reactor should be
Input AC installed to improve the input

distance should be less than
10m. Please refer to 3.7.6.

Note: 1: All series includes built-in braking units, please connect braking resistor between + / P, PR.
2: All series inclides built-in RFI filters to suppress electromagnetic interference, but if you need to comply with CE
regulations, please refer to the relevant instructions in the manual for installation.
3: In order to improve the braking ability during deceleration, the frame C / D external braking unit can be connected
between (+ / P)-(-N). For details, please refer to Section 3.7.1.
4: When adding a DC reactor on C / D frame inverter, jumper between + / P and P1 must be removed. For the selection
of reactor, refer to section 3.6.4.
5. Do not short the 10, SD, SE, 5, and PC terminals to each other.
6. Please refer to section 5.3.9 for HDO wiring.

6. If the distance between the inverter and motor is long, please use thick wires, make sure wire voltage drop is
under 2V (wire length below 500 meters).
7. Use "insulation crimp sleeve " for power supply side and load side connection.
8. After cutting off terminal power, high voltage still exist between (+/P) and (-/N) in short period of time. Within 10
minutes, do not touch terminals to avoid electric shock.
3.7.3 Ground
For safety and to reduce noise, the grounding of the inverter must be well grounded. To avoid electric shocks
and fire accident, the external metal ground wire of the equipment should be short and thick, and should be connected
to specific grounding terminals on the inverter. If several inverters are placed together, all inverters must be
connected to the common ground. Please refer to the following diagrams and ensure that no loop is formed between
grounding terminals.

3.7.4 RFI filter
SE3 series inverters are equipped with built-in RFI filters. These filters are effective in reducing electromagnetic
interference, but to meet CE standard, please refer to section 3.5.4 for installation and wiring.

Note: 1. Screwdriver, use small slotted screwdriver (the tip thickness: 0.4mm/tip width: 2.5mm).
2. If the screwdriver tip width is too narrow, it may cause terminal damage.
3. Please alignment terminals by pressing down with the slotted screwdriver, head sliding may cause damage
or injury accident inverter.
4. Installation, wire arrangement, dismounting and maintenance can only be done by qualified electrical
professional personnel.
5. Please follow the wire arrangement notice. If installation is not done by above steps, and inverter is
damaged, our company will not undertake any legal responsibility. In case there is any question on the wire
arrangement, please feel free to contact us.
