Safety Precautions at the Machine Location
Ensure when installing machines with cooling-air vents that the cooling air can flow freely
through the air vents without obstruction. Only operate the machine with the degree of
protection specified on the rating plate.
Information on
noise emission
values
EMC device
classifications
The inverter generates a maximum sound power level of <80 dB(A) (ref. 1pW)
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 temperature 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 installation 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 conducted and emitted interference in other areas.
Devices with emission class B:
- satisfy the emissions criteria for residential and industrial areas. This
also applies to residential areas in which power is supplied from the
public low-voltage grid.
EMC device classification as per the rating plate or technical specifications
EN
EMC measures 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 situation.
Mains connection
High-performance devices (> 16 A) can affect the voltage quality on the mains
network because they can feed powerful current into 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 mains network
*)
*)
see Technical Data
In this case, the plant operator or the person using the device should check
whether or not the device is allowed to be connected, where appropriate
through discussion with the power supply company.
