Size, Weight and Operating Conditions
Size and Weight
The dCS 974 dimensions correspond to a standard 2U 19" rack mount case.
Four heavy duty feet, fitted to the base, extend the overall height to slightly
greater than 2U.
Dimensions
Width 430 mm see note (i)
Height, without feet 88 mm (2U)
Height, with feet 95 mm
Depth 390 mm see note (ii)
Weight 8.5kg see note (iii)
note (i) Removable 19" rack mount ears are supplied,
taking total width to 483 mm (19").
note (ii) Measured from front panel to rear panel
connectors. Additional depth should be allowed to
accommodate cable connectors. The rotary control
knob protrudes 22mm from the front panel.
note (iii) The high quality case is necessarily heavy,
consideration should be paid to appropriate
support shelving when installing the units in a rack.
Operating Conditions
The case of the dCS 974 has no ventilation slots or fan cooling, to give:
• quiet operation (does not need to be installed in a machine room)
• internal temperature stability
• improved electrical safety
• long term reliability
• no regular maintenance or cleaning requirements
It dissipates relatively low power, so that usually allowing natural convection
provides enough cooling. Do not install the unit near heat sources such as
radiators, air ducts or direct strong sunlight. Ambient should not exceed 50°C,
should not fall below 0°C, and should be non condensing. If in doubt, the easy
test is – the dCS 974 is happy to work anywhere a human is.
