Observe Chapter, "Safety instructions" when carrying out any work at the converter.
3.1
Requirements regarding the installation site
The converter is designed for installation in closed electrical rooms in compliance with
EN 61800-5-1. A closed electrical room contains electrical equipment. Only appropriately
trained personnel may access these electrical rooms. These electrical rooms can only be
accessed by opening a door or removing a barrier using either a key or appropriate tool. The
room is clearly marked with the appropriate warning symbols.
The installation location must be dry and dust-free. 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 electrical room. If the air contains dust, filter mats can be installed
in front of the ventilation meshes of the cabinet doors and also in front of the optional canopies.
The canopy provides additional protection against water sprayed against the housing from any
direction. The canopy corresponds to degree of protection IP54.
The permissible values for climatic ambient conditions must be complied with.
The units must be derated for ambient temperatures > 40 °C (104 °F) and installation altitudes
> 2000 m.
Note
Derating data
Notes regarding the derating data are provided in the "SINAMICS S120 Cabinet Modules"
Manual, Chapter, "System overview/derating data".
The basic version of the cabinet units complies with the IP20 degree of protection in
accordance with EN 60529.
Note
Requirements for IP20
The units only satisfy the requirements to achieve IP20 after the righthand side and lefthand
side panels have been attached.
The units must be mounted and installed corresponding to the dimension drawings provided.
The
clearance to be maintained between the top of the cabinet and the ceiling is shown in the
diagram below. Additional dimensions must be taken into account if the unit has a base or
cable marshaling space.
