3.3.1 Mechanical installation: checklist
Use the following checklist to guide you through the mechanical installation procedure for the
cabinet unit. Read the safety information at the start of this operating manual before you start
working on the device.
Note
Check the boxes accordingly in the right-hand column if the activity applies to the cabinet
unit in your scope of supply. In the same way, check the boxes once you have finished the
installation procedure to confirm that the activities are complete.
Item Activity Fulfilled/Complete
1 The ambient conditions must be permissible. See "Technical specifications, General
technical specifications".
The cabinet unit must be firmly attached to the fixing points provided.
The cooling air can flow unobstructed.
2 The minimum ceiling height (for unhindered air outlet) specified in the operating manual
must be observed. The cooling air supply must be not be obstructed (see "Mechanical
installation/preparation").
3 Components that are supplied separately for transport reasons (canopy or hood) must
be fitted (see "Mechanical installation/Fitting additional canopies (option M21) or hoods
(option M23/M43/M54)").
4 The clearance around an open door (escape route) specified in the applicable accident
prevention guidelines must be observed.
5 With option M13/M78:
Choose the required metric screw connections or conduit thread connections on the
basis of the cable cross-section and drill the required holes in the blanking plates. When
the cable is fed in from above, ensure that enough room is available if the cable has to
be bent because of the cable feeder and cross-sections. The cable entries should be fed
in vertically to minimize transverse forces on the entries (see "Mechanical installation /
cable entry from above (option M13), motor connection from above (option M78)").
3.3.2 Preparation
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 operation. It may be
necessary to filter the air supplied to the installation room. If the air contains dust, filter mats
