Converter modules size D6 / D7 installed in
cabinets DCS800-A produce a considerable
amount of power loss to be removed by air
cooling. In most cases the switch room is not
capable to absorb the heated air. That is why
cabinets with converter modules sizes D6 / D7
are provided with an adapter for connection to an
air duct (air duct to be supplied for by customer).
In case there is no air duct, the option Air
Ventilation Hood is required to meet protection
class IP 21.
This option can also be used for connection to an
existing air duct outlet (solution indicated by
dashed lines).
