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, and top 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.
