Installing/Wiring the Recorder
Installation Location
Install the recorder indoors in a location that meets the following conditions.
• Instrument Panel
The recorder is designed for panel mounting. The portable type (/H5x option) is
designed to be used on the desktop.
• Well-Ventilated Location
To prevent overheating, install the recorder in a well-ventilated location.
For the panel cut dimensions when arranging multiple recorders, see page 14. Follow
the panel cut dimensions providing adequate space between instruments when other
instruments are arranged on the panel.
We recommend that you secure at least 50 mm of space from the left, right, top, and
rear panels on the portable type (/H5x option).
• Minimum Mechanical Vibrations
Choose an installation location with the minimum mechanical vibration.
Installing the recorder in a location with large mechanical vibration not only causes
adverse effects on the mechanism but also may hinder normal recording.
• Horizontal
Install the recorder horizontally (However, the recorder can be inclined up to 30
degrees backwards for panel mounting).
Note
• Condensation may occur if the recorder is moved to another place where both the ambient
temperature and humidity are higher, or if the temperature changes rapidly. In addition,
measurement errors will result when using thermocouples. In this case, let the recorder
adjust to the new environment for at least one hour before using it.
• The chart paper may be adversely affected by a rapid change in the ambient temperature
and humidity.
Do not install the recorder in the following places.
• Outdoors
• In Direct Sunlight or Near Heat Sources
Install the recorder in a place with small temperature fluctuations near room
temperature (23°C). Placing the recorder 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 recorder.
Avoid such locations.
• Near Strong Magnetic Field Sources
Do not bring magnets or instruments that produce electromagnetic fields close to the
recorder. Operating the recorder in strong magnetic fields can cause errors in the
measurements.
Installation Procedure
The recorder should be mounted on a steel panel of thickness 2 mm to 26 mm.
1. Insert the recorder from the front side of the panel (see the mounting diagram on
the next page).
2. Mount the recorder to the panel using the mounting brackets that come with the
package.
• Use two brackets to support the top and bottom or the left and right sides of
the case (remove the seal that is covering the holes for the mounting brackets
beforehand).
• The proper torque for tightening the mounting screws is 0.7 to 0.9 N•m.
