WARNING

Power Supply

Ensure that the instrument’s supply voltage matches the voltage

of the power supply before turning ON the power.

Do Not Use in an Explosive Atmosphere

Do not operate the instrument in locations with combustible

or explosive gases or steam. Operation in such environments

constitutes an extreme safety hazard. Use of the instrument in

environments with high concentrations of corrosive gas (H

, etc.) for extended periods of time may cause a failure.

YOKOGAWA's service personnel. There are dangerous high voltage

parts inside. Additionally, do not replace the fuse by yourself.

Damage to the Protective Construction

Operation of the instrument in a manner not specified in the

operation guide may damage its protective construction.

CAUTION

This instrument is an EMC class A product. In a domestic environ-

ment this product may cause radio interference in which case the

user needs to take adequate measures.

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.
