CHAPTER 2 INSTALLATION AND WIRING
2.1 Installation environment
1. Ambient temperature: -10
℃～
+40
℃
, derate to use if the temperature is above
40
℃
2. Relative humidity: ≤ 95%, no condensation
3. Vibration:
＜
0.5g
4. The inverter should be installed on the flame-retardant materials and there is
enough space for heat dissipation.
5. The inverter can output the rated power when the altitude is below 1000m. If
the altitude is above 1000m, the output power will decrease. It is recommended
to derate 1% for every additional 100m.
6. The inverter is not allowed to fall to the ground suddenly.
7. The inverter is not allowed to be installed near the electromagnetic radiation
sources.
8. The inverter is not allowed to be installed in the atmospheres with flammable,
explosive or corrosive gases.
9. The inverter is not allowed to be installed in the environments with direct
sunlight, oil mist or steam.
10. Avoid screws, cables, drilling debris and other conductive matters falling into
the inverter during installation, otherwise it may cause the inverter failure.
11. For the bad installation environments (like textile industry), it is recommended
to install the radiator outside the cabinet.

2.2.1 Functions of peripheral components
Table 2-1 Functions of peripheral components
Name
Functions
Circuit breaker
Cut off the power and protect the latter when the latter devices
have failure.
Select the circuit breaker of the breaking current by 2 times of
the inverter.
Leakage
protector
PWM high frequency chopper voltage output causes high
frequency leakage current, so select a special leakage
protector.
Contactor
Frequent switching on-off the contactor causes inverter failure,
so do not start or stop the inverter by switching on-off the main
circuit, which will affect the life of the inverter.
Input reactor
and DC
reactor
Improve the input power factor;
Reduce the impact on the system caused by the unbalance of
input power;
Suppress high harmonics and reduce external conduction;
Suppress the interference on the rectifier bridge caused by the
pulse current.
Input and
output filters
Reduce the interference of the inverter on peripheral devices.
Braking unit
Consume the feedback energy from motors and brake rapidly
