Fronius Selectiva 2040 2kW Operating Instructions Manual page 15

The air surrounding the charger must be kept free from battery acid vapour as far as pos-
sible. You should therefore avoid setting up the charger directly above the battery being
charged.
Cooling air
The charger must be set up in such a way that the cooling air can flow unimpeded through
the vents in the housing that are provided for that purpose. Ensure that there is always a
minimum of 20 cm (7.87 in) of space around the air inlets and outlets. The surrounding air
must be free from
- excessive dust content
- electrically conductive particles (carbon black or swarf)
- heat sources
Cooling air is drawn in and flows out as indicated by the arrows in the following illustrations.
NOTE! Air inlets and outlets must never be covered, not even partially. If several
chargers are set up one behind the other, they should be offset.
If the chargers are arranged in a line one behind the other without being offset, the space
between the chargers must be as follows:
- Minimum distance 20 cm (7.87 in)
The device must only be operated in a hori-
zontal position.
