♦ 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.
MASTERDRIVES chassis units are CE designated products with
standard IP00 degree of protection.
When installed in a cabinet, an additional direct touch protection is
necessary. IEC60204-1 6.2 must be observed meticulously.
For types E to G there is the option M20 for IP20 degree of protection.
If you are using water-cooled MASTERDRIVES please note that the
permissible operating pressure depends on the construction type.
Type A to G:
Operating pressure ≤ 1 bar. Operating pressures above 1 bar not
permitted! If the system is to be operated at higher pressure, the
pressure on each unit must be reduced to 1 bar initial pressure.
Type ≥ J:
Operating pressure ≤ 2.5 bar. Operating pressures above 2.5 bar not
permitted! If the system is to be operated at higher pressure, the
pressure on each unit must be reduced to 2.5 bar initial pressure.
