The servicing information contained in these operating instructions is intended
only for the use of qualified service engineers. An electric shock can be fatal.
Do not perform any actions other than those described in the documentation.
This applies even if you are qualified to do so.
All cables and leads must be secure, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or inadequately dimen-
sioned cables and leads must be immediately repaired by authorised person-
nel.
Maintenance and repair work must only be carried out by authorised person-
nel.
It is impossible to guarantee that bought-in parts are designed and manufac-
tured to meet the demands made of them, or that they satisfy safety require-
ments. Use only original spare parts (also applies to standard parts).
Do not carry out any modifications, alterations, etc. to the device without the
manufacturer's consent.
Components that are not in perfect condition must be changed immediately.
The inverter generates a maximum sound power level of < 59 dB(A)
(ref. 1 pW) when operating under full load in accordance with
IEC 62109-1:2010.
The device is cooled as quietly as possible with the aid of an electronic tem-
perature control system, and depends on the amount of converted power, the
ambient temperature, the level of soiling of the device, etc.
It is not possible to provide a workplace-related emission value for this device
because the actual sound pressure level is heavily influenced by the installa-
tion situation, the power quality, the surrounding walls and the properties of
the room in general.
Devices in emission class A:
-
Are only designed for use in industrial settings
-
Can cause line-bound and radiated interference in other areas
Devices in emission class B:
-
Satisfy the emissions criteria for residential and industrial areas.
This is also true for residential areas in which the energy is sup-
plied from the public low-voltage mains.
EMC device classification as per the rating plate or technical data.
In certain cases, even though a device complies with the standard limit values
for emissions, it may affect the application area for which it was designed (e.g.
when there is sensitive equipment at the same location, or if the site where the
device is installed is close to either radio or television receivers). If this is the
case, then the operator is obliged to take appropriate action to rectify the situ-
ation.
