3.4.2 SMALL MAINFRAME SH-1/2S BM
The ambient temperature during operation must not fall below + 5 °C or exceed
+ 40 °C (41 °F to 104 °F). Optimum operation is ensured at an ambient temperature
of 20 °C.
The mainframe is ventilated by the fan unit (8 fans) being mounted at the left side
in the mainframe. The air is sucked in at the left side of the mainframe and is ex-
hausted at the right side through the louvers. These fans serve to support air cir-
culation in the unit and to lead the heated air into the room. The power supplies in
the lower part of the carrier are cooled by two internal fans. The air is sucked in at
the front and is let out through the louvers at the rear.
In order to ensure continuous air circulation, make sure that the air slots on
the left and right side and on the rear side of the unit are not covered when
mounting the mainframe.
