Humidity should be lower than 95%, no condensing and rain water drops.
Do not mount the driver on the timber or other combustible matters.
Avoid direct sunlight.
It is strictly prohibited to install the drivers in places where have flammable,
explosive, corrosive gases or liquids;
Mount in the location free of dust, metal powder, corrosive gas or combustible
gas.
The installation foundation should be solid and free of vibration.
No electromagnetic interference, away from source of interference.
Derating use must be considered when the driver is installed at high altitude
greater than 1000 m. This is because the cooling effect of driver is deteriorated
because of the thin air. Derating 6% per 1000 m above 1000m altitude.
2.2.2 Ambient Temperature
In order to enhance operating reliability of the driver, be sure where the driver mounted
has a good ventilation; when the driver is used in a closed case, cooling fans or an
air-conditioning must be installed to keep the ambient temperature below 40℃
2.2.3 Preventive Measures
During installing, please set a shield to prevent metal debris falling into it, and remove
the shield after installing.
Please remove the protection cover board when the ambient temperature is over
40° C or the internal temperature is too high due to other reasons. Otherwise the driver
should be derated. After removing the protection cover, pay attention to avoid small
parts falling into the driver.
2.3 Installation Direction and Space
Drivers of this series are all equipped fans for forced cooling. In order to be an effective
cooling cycle, the driver must be mounted in the vertical direction, up, down, left and
right away from adjacent articles or baffle (wall) maintain adequate space, as Figure 2-1
