Installation
♦ Foreign particles
Requirements at the
point of installation
♦ Dust, gases, vapors
♦ Cooling air
NOTE for types
MASTERDRIVES chassis units are CE designated products with
E to G
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.
Water cooling
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.
5-2
The units must be protected against the ingress of foreign particles
as otherwise their function and operational safety cannot be
ensured.
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.
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.
