17.1 Installation Location
The instrument should be installed in indoor locations meeting the following conditions:
• Instrumented panel
This instrument is designed to be mounted in an instrumented panel. Mount the
instrument in a location where its terminals will not inadvertently be touched.
• Well ventilated locations
Mount the instrument in well ventilated locations to prevent the instrument’s internal
temperature from rising. However, make sure that the terminal portions are not
exposed to wind. Exposure to wind may cause the temperature sensor accuracy to
deteriorate. To mount multiple indicating controllers, see the external dimensions/
panel cutout dimensions which follow. If mounting other instruments adjacent to the
instrument, comply with these panel cutout dimensions to provide sufficient clearance
between the instruments.
• Locations with little mechanical vibration
Install the instrument in a location subject to little mechanical vibration.
• Horizontal location
Mount the instrument horizontally and ensure that it is level, with no inclination to the
right or left.

Note
If the instrument is moved from a location with low temperature and low humidity to a place with
high temperature and high humidity, or if the temperature changes rapidly, condensation will
result. Moreover, in the case of thermocouple inputs, measurement errors will result. To avoid
such a situation, leave the instrument in the new environment under ambient conditions for
more than 1 hour prior to using it.
