2.2 How to Install the DA100
Installation Conditions
The instrument must be installed in a location where the following conditions are met.
· Ambient temperature: 0 to 50 °C
However, in case you mount the subunits DS400/DS600 directly to a panel, or mount them in a
rack, it is possible to use them in a range of –10 to 60
°C.
WARNING
• When the environmental temperature is 50 ° C or more, the temperature
of the rear panel may rise to more than 70 ° C. Thus, touching the rear
panel under these circumstances has the danger of sustaining burns.
• To prevent a fire, always use the instrument in a vertical position, and
do not block the upper side of the modules (a space of at least 3cm is
necessary).
· Ambient humidity: 20 to 80%RH for –10 to 40
°C, 10 to 50%RH for 40 to 50 °C, 5 to 30%RH for
50 to 60 °C (However, no condensation should be present.)
· Installation location: Room
· Installation height: Altitude up to 2,000 m
Note
Internal condensation may occur if the instrument is moved to another place where both the ambient
temperature and humidity are higher, or if the temperature changes rapidly. In case of thermocouple input,
this might result in erroneous measurements. In those cases, allow the instrument to achieve equilibrium
with to its new environment for at least one hour before starting operation.
Never install the instrument in any of the following locations:
· in direct sunlight or near heat sources;
· where an excessive amount of soot, steam, dust or corrosive gases are present;
· near strong magnetic field sources;
· near high voltage equipment or power lines;
· where the level of mechanical vibrations is high;
· in an unstable place.
Installation Method
The data acquisition unit DA100 and the subunit DS400/DS600 can be installed on the floor,
directly to a panel, or can be mounted in a rack. Units equipped with screw type terminals should
only be used in panel installations.
Floor installation
Swing the feet which are located under the unit to the front as shown in the figure below, and
place the unit vertically. When there might a possibility of the unit tumbling over after wiring,
fasten the feet to the surface using the accessory M4 screws.
