INVERTER INTRODUCTION 33
3.5 Installation and wiring
3.5.1 Transportation
Hold the body when carrying and don’t only hold the cover or any part of the inverter, otherwise it may drop down.
3.5.2 Stockpile
The product must be placed in the packaging box before installation. In order to make the product conform to the scope
of warranty of the company and facilitate maintenance in the future, please pay attention to the following matters when
storing if the inverter will not be used temporarily:
1. Must be placed in dry places without dirt and dust.
2. The environment temperature for storage place must range from -20℃ to +65℃.
3. The relative humidity for storage place must range from 0% to 95%, and no condensation.
4. Avoid storing in the environment containing corrosive gas or liquid.
5. It’s better to be packed properly and kept on shelf or table.
Note:1. Even if the storing place humidity meets the standard requirements, icing and condensation can also occur if
the temperature changes rapidly, thus should be avoided.
2. Don't place it on the ground, it should be placed on a shelf. If the environment is bad, put desiccant in the
packaging bag.
3. If the storage period is more than 3 months, the storing temperature should not be higher than 30℃.
Considering that capacitors will easily degrade in high temperature without being powered on.
4. If the inverter is installed in a machine or control panel when not in use (especially in construction site or humid
and dusty places), the inverter should be removed and put in suitable environment according to the above
storage conditions.
5. If the inverter isn’t power on for a long time, the capacitors will degrade. Do not place it for more than one year
without being powered on.
3.5.3 Installation notice
Before installing, please confirm whether meet the conditions listed in the table below:
Ambient temperature
Heavy load：-10 ~ +50℃ (non-freezing)，Light load：-10 ~ +40℃ (non-freezing), please refer to 3.4.5 Class
of protection and operation temperature for details.
Ambient humidity
Below 90%Rh (non-condensing).
Storage temperature
-20 ~ +65℃.
Surrounding
environment
Indoor, no corrosive gas, no flammable gas, no flammable powder.
Altitude
Altitude below 3000 meters, when altitude is above 1,000 moderate the rated current 2% per 100 m
Note 1: According to the safety regulation EN61800-5-1, which is required to declare in CE certification, this
series of inverters can be installed in an environment of over-voltage class II when the altitude is less than
3000m. When the altitude is less than 2000m, can be installed in harsher conditions that meet the
requirements of over-voltage class III.
Vibration
Vibration below 5.9 m/s
