5.3 Standard enclosure dimensions and clearances
Standard ESI-S enclosures have dimensions of 588 x 326 x 795 mm (width x depth x
height). Each enclosure contains one power unit and is fitted with its own main AC
contactor. Power cables with protecting fuses can be connected to each ESI-S from the
bottom.
A spacing of 30 mm between the inverter sides and walls or other enclosures is
recommended. However the unit can rest on its back against a wall.
A spacing of 500 mm below the inverter bottom and above the inverter top is
recommended.

If an inverter system consists of more than one unit, the units should be installed next
to each other. If it is not otherwise possible, additional units can be mounted above the
existing unit(s). However, care has to be taken that the hot air of the bottom unit cannot
be sucked in by the fans of the unit mounted above. An example of such an arrangement
is given in
