Storage and installation location
Storage
The units must be stored in clean, dry rooms. The storage temperature
must be between -25° C (-13° F) and +70° C (+158° F). Temperature
fluctuations exceeding 20 K per hour are not permissible.
Note:
AC drive converters and rectifier units include aluminum-Elko
DC link capacitors. They can be stored for a maximum of 2
years in a no-voltage condition, for a storage temperature of
40 °C. If they are stored for longer than two years, these DC
link capacitors must be re-formed before the unit is
commissioned.
Minimum requirements regarding the installation location
•
The rooms in which the drive converters are to be installed should be
dust-free. Dust-laden air must be filtered (
3K3 according to DIN IEC 721-
3-3)
.
•
The ambient temperature must be within the range 0...40° C (23° F ...
104 ° F).
•
The relative air humidity may not exceed 90 %; moisture condensation
is not permissible.
•
The fan airflow may not be restricted. The minimum clearances for the
air intake and air discharge may not be restricted using additional
mounted components.
•
The air drawn in may not contain any aggressive or electrically
conductive gases which could have a negative impact on the
functioning of the equipment.
•
The unit dissipates heat and increases the temperature of the ambient
air. Thus, sufficient clearance must be maintained to heat-sensitive
equipment.
Installation altitudes exceeding 1000 meter above sea level:
For installation altitudes exceeding 1000 meters above sea level, the drive
converter or inverter must be de-rated corresponding to the adjacent
diagram.
