The inverter generates a maximum sound power level of < 80 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 grid.
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.
High-performance devices (> 16 A) can affect the voltage quality of the grid
because of a high output current in the main supply.
This may affect a number of types of device in terms of:
-
connection restrictions
- criteria with regard to maximum permissible mains impedance *)
- criteria with regard to minimum short-circuit power requirement *)
*) at the interface with the public grid
see Technical Data
In this case, the operator or the person using the device should check whether
or not the device is allowed to be connected, where appropriate through dis-
cussion with the power supply company.
Electrical installations must only be carried out according to relevant national
and local standards and regulations.
