5.3Clearances around DNT2Mi

When installing DNT2Mi on a wall or freely on a horizontal level, you must ensure that there is an adequate space for connecting cables. Recommended clearances are shown in Figure 11.

In a modem-shelf installation, slot sizing of the shelf ensures adequate horizontal clearances between the units.

Heat released from the unit is insignificant, and does not therefore set requirements on the clearances around the equipment. DNT2Mi is cooled through natural convection through air inlets and outlets located in the bottom and top of it.

Caution

Do not cover DNT2Mi. The air inlets and outlets must be unobstructed to maintain proper circulation of air.

Do not cover!
