Installation and Wiring
Installation Location
Install the DX indoors in a location that meets the following conditions.
• Instrumentation Panel
The DX is designed to be installed in an instrumentation panel except for the desktop
type.
• Well-Ventilated Location
To prevent overheating, install the DX in a well-ventilated location. For the panel cut
dimensions when arranging multiple DXs, see the page 51. Follow the panel cut
dimensions providing adequate space between instruments when other instruments
are arranged on the panel. For the desktop type, we recommend that a space of at
least 50 mm be provided around the left, right, top, and rear panels of the DX.
• Minimum Mechanical Vibrations
Choose an installation location with the minimum mechanical vibration. Installing the
DX in a location with large mechanical vibration not only causes adverse effects on
the mechanism but also may hinder normal recording.
• Horizontal
Install the DX horizontally (However, the DX can be inclined up to 30 degrees
backwards for panel mounting).
Note
Condensation may occur if the DX is moved to another place where the ambient
temperature is higher, or if the temperature changes rapidly. In addition, measurement
errors will result when using thermocouples. If this happens, let the DX adjust to the new
environment for at least one hour before using it.
Do not install the DX in the following places.
• Outdoors
• In Direct Sunlight or Near Heat Sources
Install the DX in a place with small temperature fluctuations near room temperature
(23°C). Placing the DX in direct sunlight or near heat appliances can cause adverse
effects on the internal circuitry.
• Where an Excessive Amount of Soot, Steam, Moisture, Dust, or
Corrosive Gases Are Present
Soot, steam, moisture, dust, and corrosive gases will adversely affect the DX. Avoid
such locations.
• Near Strong Magnetic Field Sources
Do not bring magnets or instruments that produce electromagnetic fields close to the
DX. Operating the DX in strong magnetic fields can cause errors in the measurements.
• Where the Viewing of the Display Is Poor
The DX uses a TFT color LCD for the display. Therefore, viewing of the display from
an extreme angle is difficult. Install the DX so that the user can view the display from
the front.
