3. How to Install
■
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 inter-
nal 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 mul
-
tiple 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.
Do not mount the instrument in the following locations:
• Outdoors
• Locations subject to direct sunlight or close to a heater
Install the instrument in a location with stable temperatures that remain close to an
average temperature of 23°C. Do not mount it in locations subject to direct sunlight
or close to a heater. Doing so adversely affects the instrument.
• Locations with substantial amounts of oily fumes, steam, moisture, dust, or
corrosive gases
The presence of oily fumes, steam, moisture, dust, or corrosive gases adversely
affects the instrument. Do not mount the instrument in locations subject to any of
these substances.
• Areas near electromagnetic field generating sources
Do not place magnets or tools that generate magnetism near the instrument. If the
instrument is used in locations close to a strong electromagnetic field generating
source, the magnetic field may cause measurement errors.
• Locations where the display is difficult to see
The instrument uses an LCD for the display unit, and this can be difficult to see
from extremely oblique angles. Mount the instrument in a location where it can be
seen as much as possible from the front.
• Areas close to flammable articles
Absolutely do not place the instrument directly on flam-
mable surfaces. If such a circumstance is unavoidable
and the instrument must be placed close to a flammable
item, provide a shield for it made of 1.43 mm thick plated
steel or 1.6 mm thick unplated steel with a space of at
least 150 mm between it and the instrument on the top,
bottom, and sides.
• Areas subject to being splashed with water
WARNING
Be sure to turn OFF the power supply to the controller before in-
stalling it on the panel to avoid an electric shock.
