Preparatory Steps
On-Site Requirements
The cabinet units are suitable for installation in general operating areas (DlN VDE
0558 / Edition 7.87, Part 1 / Section 5.4.3.2.4).
The standard specifies the following:
When power conversion units are installed in general operating areas, live parts
must be protected in such a way that they cannot be touched either directly or
indirectly.
The operating areas must be dry and free of dust. The air supplied must not
contain any electrically conductive gas, vapors, or dust, which could impair the
function of the devices. It may be necessary to filter the air supplied to the
installation room. If the air contains dust, filter mats (option M54) can be installed in
front of the hoods (IP54) and the ventilation grilles on the cabinet doors.
The ambient conditions for the units in the operating rooms must not exceed the
values of code F in accordance with EN 60146. At temperatures > 40°C (104°F)
and altitudes > 2000 m, the devices must be derated.
The basic version of the cabinet units complies with the IP20 degree of protection
in accordance with EN 60529.
The cabinet units are installed in accordance with the dimension drawings
supplied. The clearance between the top of the cabinet unit and the ceiling is also
specified on the dimension drawings.
The cooling air for the power unit is drawn in from the front through the ventilation
grilles in the lower part of the cabinet doors. The warmed air is expelled through
the perforated top cover or the ventilation grilles in the top cover (with option
M23/M54). Cooling air can also be supplied from below through raised floors or air
ducts, for example. To allow this, you have to create openings in the 3-section
bottom plate.
According to EN 61800-3, the cabinet units are not suitable for use in low-voltage
public networks that supply residential buildings. High-frequency interference may
occur if they are used in this type of network.
Unpacking the Cabinet Units
Check the delivery against the delivery note to ensure that all the items have been
delivered. Check that the cabinet is intact.
The packaging material must be discarded in accordance with the applicable
country-specific guidelines and rules.
Required Tools
To install the connections, you will require:
• Spanner or socket spanner (w/f 10)
• Spanner or socket spanner (w/f 13)
• Spanner or socket spanner (w/f 18/19)
• Hexagon-socket spanner (size 8)
