8.2 -
CAUTION!
Installation and work environment. Installation is allowed in a micro-environment with:
•
Environment conditions class 3K3
(IEC 721-3-3): that implies, among other things, a
working temperature from +5°C to +40°C and relative humidity from 5% to 85% non condensing.
•
Pollution degree 2
: that implies, among other things, that installation in environments in
which explosive and/or flammable and/or chemically aggressive and/or electrically conductive
gas, vapor or dust could be present is strictly forbidden.
•
Mechanical conditions class 3M1
(IEC 721-3-3).
•
Maximum operating altitude:
2000 meters.
If the environment in which the machine is used does not satisfy these conditions, suitable
conditioning systems have to be provided for the enclosure.
8.3 -
Storage environment in original enclosure:
•
Temperature: from -25°C to +55°C. Relative humidity: from 5% to 95%.
•
Environment conditions class 1K3 (IEC 721-3-1). Pollution degree 2.

The drives generate some amount of heat (see chap. 7.1). Take care of this in considering the total
amount of heat generated in the enclosure in which the drives are located. In order to make easier
air circulation in the drive, install the drive vertically (not turned upside down) with at least 5 cm of
free space over and under the drive and 1 cm to the left and the right of the drive. Do not obstruct air
gratings.
