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.
