Keep an area of 50 cm at the top and bottom of the unit and 30 cm at the side free of obstacles. Only in
this way will the unit's cooling system operate correctly.
6.2. Environmental conditions
Environmental operating conditions indicated in section "2.8. Tables of specifications" must be taken into account
when choosing the location of the unit.
The surrounding atmosphere must be clean and at temperatures above 40 ºC the relative humidity must be
between 4% and 50%. Higher percentages of relative humidity up to 95 % are tolerated at temperatures below 30
ºC.
It should be borne in mind that moderate condensation may occasionally occur as a consequence of temperature
variations. For this reason, apart from the unit's own protection, it is necessary to monitor these units once they
have been started up on sites where the conditions described above are not expected to be present.
In the event of condensation, never apply voltage to the unit.
6.3. Supporting Surface and Fastening
To guarantee good heat evacuation and promote sealing, the units must be placed on a perfectly vertical wall or,
failing this, with a slight slope of a maximum of +85° or -85°.
Reserve a solid wall to which to attach the unit. It must be possible to drill the wall and fit suitable wall anchors
and self-tapping screws to support the unit's weight.
The packaging includes a full-scale template of the unit to help you mark the fixing holes on the wall.
6.4. Protection of the connection to the electric grid
It is necessary to install protection elements in the connection between the inverter and the electric grid.
