EMC Precautions
In special cases, there may still be interference for the specified application
area despite maintaining standardized emission limit values (e.g. when
sensitive equipment is located at the setup location or when the setup
location is near radio or television receivers).
In this case, the operator is obliged to take proper action to rectify the
situation.
Grid connection
Devices with a high output (> 16 A) can influence the voltage quality of the
grid due to a high current input into the main supply.
This can affect several device types in the form of:
-
Connection limitations
-
Requirements regarding permitted mains impedance
*)
-
Requirements regarding minimum required short circuit power
*)
*)
for each interface to the public grid
See technical data
In this case, the operator or the user of the device must make sure whether
or not the device may be connected, if necessary by contacting the power
supply company.
Information on
Noise Emission
Values
The inverter generates a maximum sound power level of <80dB(A) (ref.
1pW) at full-load operation according to IEC 62109-1.
The cooling of the device takes place via an electronic temperature control
system at the lowest possible noise level and depends on the power used,
ambient temperature and the soiling level of the device, etc.
A workplace-related emissions value cannot be provided for this device
because the actual noise level that occurs depends strongly on the installati-
on situation, the grid quality, the surrounding walls and the general properties
of the space.
EMC Device
Classifications
Devices in emission class A:
-
Are only designed for use in industrial settings
-
Can cause grid-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
supplied from the public low-voltage grid.
