At temperatures > 40 °C (104 °F) or altitudes > 2000 m, derating is required.
The basic version of the cabinet units complies with the IP20 degree of protection in
accordance with EN 60529.
Installation is realized in accordance with the dimension drawings supplied. The clearance
between the top of the cabinet and the ceiling is also specified in the dimension drawings.
The cooling air for the power unit is drawn in from the front through the ventilation grills in the
lower part of the cabinet doors. The hot air is discharged through the perforated top cover or
the ventilation grilles in the top cover (with option M13/M23/M43/M54/M78). Cooling air can
