Safety Measures
at the Installation
Location When installing devices with openings for cooling air, ensure that the cooling air can enter
and exit unhindered through the vents. Only operate the device in accordance with the de-
gree of protection shown on the rating plate.

EMC Measures
Grid Connection
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.
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 with emission class A:
- are only designed for use in an industrial setting
- can cause line-bound and radiated interference in other areas
Devices with emission class B:
- satisfy the emissions criteria for residential and industrial areas. This is
also true for residential areas in which the energy is supplied 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
