Explanation of
Safety Warnings!
ud_fr_se_sv_01381 012012 II
Maintenance and repair may only be carried out by an authorized specialist.
The use of third-party parts does not guarantee that they were designed and
manufactured according to operational demands and safety requirements.
Use only original spare parts (also applies to standard parts).
Do not carry out any alterations, installations or modifications to the device
without first obtaining the manufacturer’s permission.
Immediately replace any components that are not in perfect condition.
Safety Precauti-
ons at Equipment
Location
When installing devices with air vents, make sure that cool air can flow freely through the
vents unobstructed. The device should only be operated in accordance with the protec-
tion class listed on the rating plate.
The equipment may only be operated in compliance with its intended use.
Any other purpose does not constitute intended use. The manufacturer is not
responsible for any damages resulting from unintended use.
Intended use also includes:
- reading and complying with all general information as well as safety
information and warnings from the operating instructions
- compliance with all inspection and maintenance requirements
- installation as per operating instructions
Where appropriate, the following guidelines should also be applied:
- Utility company regulations regarding grid feed-in
- Information from solar module manufacturer
Intended Use
Operation and/or storage of the device outside of the stipulated range does
not constitute intended use. The manufacturer is not responsible for any
damages resulting from unintended use.
Please refer to the technical data in your operating instructions for informati-
on about permitted ambient conditions.
Ambient Conditi-
ons
Qualified Person-
nel
The servicing information contained in these operating instructions is intended
only for the use of qualified service engineers. An electric shock can be fatal.
Please do not perform any actions other than those described in the docu-
mentation. This also applies to qualified personnel.
All cables and wires must be secured, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or under-dimensioned
cables and wires must be repaired immediately by an authorized specialist.

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.
EMC device classification as per the rating plate or technical data
