Spacing between modules and other equipment in the panel
The RTU requires free spaces around it. This is necessary to enable the correct handling of the
equipment. Furthermore, such spacing should be respected in order to allow the air flow through the
CPU, in convection type, maintaining the equipment temperature. The Figure 8-2 and Table 8-1
indicate the spacing required by Hadron Xtorm Series modules.

Gutter Sizing
For the sizing of the gutter, in addition to the area occupied by the wires, observe the internal heating
in the gutter, caused by the heat dissipated by the wires, which can lead to a reduction in the gutter
area occupancy.
Use the following rule: gutter area >= sum of the wiring area/0.4
Wiring area = (3.14 * radius ^ 2)
It is considered as “wiring area” the total area, including the insulation.
Horizontal/Vertical Mounting
Hadron Xtorm Series allows the use of RTU in horizontal orientation. Vertical mounting is not
allowed in the rack.
