This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Cooling section). For mounting in 19"
apparatus cabinet without forced ventilation, a minimal spacing of 1U according to IEC
60297 or 45 mm (1.75") above/below is recommended. With forced ventilation, no
minimal spacing is required as long as the temperature of the rear cooling plates does
not 85
º C (+185 º F).
For wallmounting in an area without forced ventilation, a minimum spacing of 45 mm
(1.75") above/below and 10 mm (0.4") left/right is recommended. For areas with forced
ventilation, no minimal spacing is required as long as the temperature of the rear cooling
plates does not 85
º C (+185 º F).
