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

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

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.

General remarks

Basic system
principle

Device concept

FRONIUS IS inverters open up totally new prospects for an off-grid power supply. The
new stand-alone inverter is extremely light, can be connected in parallel, offers simple
on-site servicing, total flexibility in terms of configuration and has an informative graphi­cal display.

Stand-alone systems store the power produced (e.g. from solar modules) in a battery
and make it available as alternating current when required.

As the user’s electricity needs increase, up to 5 additional inverters per phase can be
connected in parallel in 3 phase (maximum) operation, giving a total of 15 FRONIUS IS
inverters in a system. The original set-up can be upgraded at any time by installing
additional inverters, making the system extremely flexible and future-proof.

The backlit, self-explanatory display is a highlight in itself. The display provides informati­on on the entire system in both graphical and alphanumerical format. The well laid-out
display provides detailed information and shows important readings including battery
charge level and consumption values.

The company’s decades of experience in high frequency technology means that Fronius
devices are exceptionally fault resistant. If a fault should occur, the faulty circuit board
can be replaced quickly and easily on site by our After-Sales Service or by the installer.
The device does not have to be dismantled or sent away. The result - downtime is kept
to a minimum and the power supply is restored in the shortest time possible.

Application areas The FRONIUS IS is ideal for use on holiday cottages, mobile homes and boats right

through to entire village power supplies that can be easily supplied by stand-alone
systems.

Options

Available options:

- Ambient temperature sensor

- Battery temperature sensor

- SYNC module IS kit
