Chapter 1 Production Overview
1.1 Precautions on commodity inspection and storage
Before delivery, all goods are under strictly quality control and well
packed. However it may damage during the international transportation,
please check them carefully:
1. Check the package condition to make sure no damage happened
during transportation
2. Open the package and find out the user manual
3. Check the nameplate information on side of the inverter, be sure you
get the right product or spare parts
For any problem you may have, please contact your supplier!
STORAGE
Inverter should be packed and stored in ventilate and dry place. Keep
it away from corrosive gas, liquid and stained conditions.
The relative Humidity suggest to be 0% - 95% , no condensing,
The allowed temperature range is from -25℃to 65℃
Transportation Cautions:
Temperature range is from -25℃to 70℃
Relative Humidity is allowed to be 5% - 95%
Atmospheric pressure is allowed to be from 70kpa to 106kpa.

2.5 Control circuit wiring
The Control circuit wiring should be separated from the main circuit
wiring. Do not put them together in one slot.

2.6 Safety Considerations
1. Please use right wires according to relative laws. When the distance
between inverter and motor is over than 25meters, should raise wiring
standard.
2. Between the three-phase AC input power and main circuit terminal
(R,S,T) there must be a fuse switch. Make an electromagnetic contactor
in series to cut off power before the inverter steer its protection.
3. Ground terminal to the first grounded wiring.
The ground impedance must be less than 100R. Or make the ground
wire dimension is same with the main circuit wires.

4.The inverter should not joint ground with other high current loads, must
be separated.
5.The ground wire should be shorter.
6.When the inverters are common ground, don’t make a ground loops.
7.Confirm the voltage and maximum current.
8. The power indicator on the side of inverter shows the voltage inside
the inverter.
9.When the power indicator is lighting ,do not connect or disassemble
wires.
10. The SD4000 series is not equipped with the brake resistor. In the
occasion of frequently starting or stopping inverters, please install brake
resistor or unit.
11.Please connect the inverter’s terminal U,V,W with motors’
correspondingly. If the FWD lights, means the inverter is forward rotation;
if the REV lights, means the inverter is reversing. When the inverter is
forward rotation and motor is reversing,swap any two terminals of the
motor.
Do not connect the AC power with output terminals of the inverter.
