2.2 Installation
Installation Location
Install the instrument indoors in the following locations.
• In temperatures of –20 to 60°C
If the ambient temperature is –20 to 40°C, place the instrument in a location where the
humidity is 20 to 80% RH. For 40 to 50°C, the humidity should be 10 to 50%. For 50 to
60°C, the humidity should be 5 to 30%. However, no condensation should be present.
Also note that the temperature range of certain modules is –20 to 50°C.
Note
Condensation may occur if the instrument is moved to another place where the ambient
temperature is higher, or if the temperature changes rapidly. Measurement errors can occur
when using thermocouple input. In this case, let the instrument adjust to the new environment
for at least one hour before using the instrument.
• Locations where the operating altitude is 2000 m or less
• Well-ventilated locations
Install the instrument in a well-ventilated location to prevent the temperature inside the
instrument from rising.
• Location where mechanical vibration is small
Select a location with small mechanical vibration for installation.
• Horizontal location
Install the instrument on a flat, even surface.
Do not install the instrument in the following places.
• Dangerous locations where flammable liquids, vapors, or dust is present
• In direct sunlight or near heat appliances
Select a location with the smallest fluctuation from room temperature (23°C) as
possible. Placing the instrument in direct sunlight or near heat appliances can cause
adverse effects.
• Where an excessive amount of soot, steam, humidity, dust, or corrosive
gas is present
Soot, steam, humidity, dust, and corrosive gas can cause adverse effects on the
instrument. Avoid installing the instrument in an environment with a high level of such
substances.
• Near magnetic field sources
Install the instrument in a location where the magnetic field is 400 A/m or less. Avoid
bringing instruments that produce magnetic fields or magnets near this instrument.
Using the instrument near a strong magnetic field source can cause measurement
errors.
Installation Procedures
CAUTION
When attaching the instrument to DIN rails, use metal plates at least 2 mm thick
in three places to secure the unit and prevent it from falling.
The MW100 Data Acquisition Unit can be used on the desktop, placed on a floor, rack
mounted, or panel mounted. In all cases, be sure to install the instrument in a vertical
position.
