2.3 Other dangers when using the cooling

Particularly when the cooling unit is externally mounted
(see section 5 "Installation"), there is a risk that the en-
closure could become unbalanced and tip over.
 In such cases, the enclosure should be bolted to the
floor as a precaution.
If the air inlet or outlet of the cooling unit is obstructed,
there is a risk of air short-circuits, resulting in inadequate
climate control.
 Please ensure that the electronic assemblies in the en-
closure are installed in accordance with section 5.3.1
"Assembly instructions".
 Where applicable, use suitable components to divert
the air.
 Please observe the prescribed minimum distances at
the installation site as outlined in section 5.3.1 "As-
sembly instructions".
