Fronius IG 300 - Manual (Page 50)

WARNING! Danger due to mains voltage and DC voltage from solar modules.
The connection area should only ever be opened by an authorised electrical
engineer. The power modules must only be opened by a trained FRONIUS
service technician, and only when the power is disconnected.
The FRONIUS IG is available in IP 20 or IP 43 versions. The IP 20 version is intended
exclusively for installation in closed rooms but is also suitable for operation in containers.
In addition, the IP 43 version can also be used in agricultural premises and protected
outdoor locations. If used in either of these cases, ensure that the FRONIUS IG
-
is not exposed to direct sunlight
- is protected from the rain
To make the most of the benefits provided by both protection versions, you should also
comply with the following requirements:
- Do not increase mains impedance unnecessarily by using an AC lead with too small
a cross section between the FRONIUS IG and the in-house distribution point.
- The ambient temperature should not fall below -20 °C nor should it exceed +50 °C.
- The airflow within the inverter is from front to back (cold air taken in at the front, hot
air emitted at the rear).
- Under certain operating conditions, the FRONIUS IG may emit a certain amount of
noise, therefore it is not advisable to install it in the immediate vicinity of living
quarters.
- The FRONIUS IG should not be installed in an area that is excessively dusty.
- The FRONIUS IG must not be installed in areas in which dust containing conductive
particles (e.g. iron filings) may form.
- When installing the FRONIUS IG care should be taken to ensure that the display
unit remains below eye level. This ensures that the display will always be easy to
read
The door on the FRONIUS IG 500 is fitted with a cylinder lock as standard. A different
lock cylinder can be fitted if required.
CAUTION! Failure to connect an appropriate earth lead may result in serious
injury or damage. The screws on the power modules provide suitable a protec-
tive earth for the housing, and the screws may not be replaced under any
circumstances unless a reliable earth connection is put in place.
WARNING! Falling equipment can cause serious or even fatal injury. When
moving the FRONIUS IG by crane it is essential that all four of the dedicated
attachment points are used.
