NOTICE
5-2
♦ Foreign particles
The units must be protected against the ingress of foreign particles
as otherwise their function and operational safety cannot be
ensured.
♦ Dust, gases, vapors
Equipment rooms must be dry and dust-free. Ambient and cooling
air must not contain any electrically conductive gases, vapors and
dusts which could diminish the functionality. If necessary, filters
should be used or other corrective measures taken.
♦ Cooling air
The ambient climate of the units must not exceed the values of DIN
IEC 721-3-3 class 3K3. For cooling air temperatures of more than
40°C (104°F) and installation altitudes higher than 1000 m, derating
is required.
Water cooling
When using water-cooled MASTERDRIVES, please take note that no
higher than 1 bar operating pressures are permitted!
If the system is to be operated at higher pressure, the pressure on each
unit must be reduced to 1 bar initial pressure.
