Safety Precautions

This product is designed to be used by a person with specialized knowledge.

This instrument is an IEC safety class I (provided with terminal for protective earth

grounding). The general safety precautions described herein must be observed during all

phases of operation. If the instrument is used in a manner not specified in this manual,

the protection provided by the instrument may be impaired.

This manual is an essential part of the product; keep it in a safe place for future

reference. Yokogawa Electric Corporation assumes no liability for the customer’s failure

to comply with these requirements.

The following symbols are used on this instrument.

Refer to the user's manual.

This symbol appears on dangerous locations on the instrument which require

special instructions for proper handling or use. The same symbol appears in the

corresponding place in the manual to identify those instructions.

IM AQ6373B-02EN

Failure to comply with the precautions below could lead to injury or death or

damage to the instrument.

WARNING

• Use the Instrument Only for Its Intended Purpose

The optical measuring instrument is designed to measure the optical

characteristics of light sources and evaluate their performance. Do not use this

instrument for anything other than as an optical measuring instrument.

• Check the Physical Appearance

Do not use the instrument if there is a problem with its physical appearance.

• Use the Correct Power Supply

Make sure that the power supply voltage matches the instrument’s rated supply

voltage and that it does not exceed the maximum voltage range of the power

cord to use.

• Use the Correct Power Cord and Plug

To prevent the possibility of electric shock or fire, be sure to use the power cord

for the instrument. The main power plug must be plugged into an outlet with a

protective earth terminal. Do not invalidate this protection by using an extension

cord without protective earth grounding.

Further, do not use this power cord with other instruments.

• Connect the Protective Grounding Terminal

Make sure to connect the protective earth to prevent electric shock before

turning ON the power. The power cord that you can use for the instrument is a

three-prong cord. Connect the power cord to a properly grounded three-prong

outlet.

• Do not Impair the Protective Grounding

Never cut off the internal or external protective earth wire or disconnect the

wiring of the protective earth terminal. Doing so poses a potential shock hazerd.

• Do not Operate with Defective Protective Grounding or Fuse

Do not operate the instrument if the protective earth or fuse might be defective.

Make sure to check them before operation.

• Reference light source output light (when the built-in light source

specification is -L1)

The instrument has a built-in reference light source for alignment adjustment,

and infrared light is always being output from the optical output connector. Never

look into the optical output connector. Infrared light entering the eyes can cause

severe injury and loss of vision.

• Do not Operate in an Explosive Atmosphere

Do not operate the instrument in the presence of flammable liquids or vapors.

Operation in such environments constitutes a safety hazard.

• Do Not Remove the Covers or Disassemble or Alter the Instrument

Only qualified YOKOGAWA personnel may remove the covers and disassemble

or alter the instrument.

Opening the cover is dangerous, because some areas inside the instrument

have high voltages.

• Install or Use the Instrument in Appropriate Locations

• This instrument is designed to be used indoors. Do not install or use it outdoors.

• Install the instrument so that you can immediately remove the power cord if

an abnormal or dangerous condition occurs.

Safety Precautions

IM AQ6373B-02EN

CAUTION

Operating Environment Limitations

This product is a Class A (for industrial environment) product. Operation of this

product in a residential area may cause radio interference in which case the user is

required to correct the interference.

French

AVERTISSEMENT

• Utiliser l’instrument aux seules fins prévues

Cet instrument de mesure optique est prévu pour mesurer les caractéristiques

optiques des sources lumineuses et évaluer leur performance. Ne pas utiliser

cet instrument à d’autres fins que celles de mesure optique.

• Inspecter l’apparence physique

Ne pas utiliser l’instrument si son intégrité physique semble être compromise.

• Vérifier l’alimentation

Assurez-vous que la tension d’alimentation correspond à la tension d’alimentation

nominale de l’appareil et qu’elle ne dépasse pas la plage de tension maximale

du cordon d’alimentation à utiliser.

• Utiliser le cordon d’alimentation et la fiche adaptés

Pour éviter tout risque de choc électrique, utiliser exclusivement le cordon

d’alimentation prévu pour cet instrument. La fiche doit être branchée sur une

prise secteur raccordée à la terre. En cas d’utilisation d’une rallonge, celleci

doit être impérativement reliée à la terre. Par ailleurs, ne pas utiliser ce cordon

d’alimentation avec d’autres instruments.

• Brancher la prise de terre

Avant de mettre sous tension, veiller à brancher la mise à la terre de protection

afin d’éviter les chocs électriques. Le cordon d’alimentation que vous utilisez

pour l’instrument est un cordon à trois broches.

Brancher le cordon d’alimentation sur une prise de courant à trois plots et mise

à la terre.

• Ne pas entraver la mise à la terre de protection

Ne jamais neutraliser le fil de terre interne ou externe, ni débrancher la borne

de mise à la terre. Cela pourrait entraîner un choc électrique ou endommager

l’instrument.

• Ne pas utiliser avec un conducteur de terre ou un fusible défectueux

Ne pas utiliser l’instrument si le conducteur de terre ou le fusible est défectueux.

Vérifier le conducteur de terre et le fusible avant d’utiliser l’instrument.

• Source de lumière de référence (lorsque la source de lumière intégrée

correspond aux caractéristiques L1)

Cet instrument dispose d’une source de lumière de référence intégrée pour

les ajustements d’alignement. La lumière infrarouge est toujours émise depuis

le connecteur de sortie optique. Ne regardez jamais directement dans le

connecteur de sortie optique. La lumière infrarouge risquerait de gravement

vous blesser ou de provoquer une perte de vision.

Safety Precautions

viii

IM AQ6373B-02EN

• Ne pas utiliser dans un environnement explosif

Ne pas utiliser l’instrument en présence de gaz ou de vapeurs inflammables.

Cela pourrait être extrêmement dangereux.

• Ne pas retirer le capot, ni démonter ou modifier l’instrument

Seul le personnel YOKOGAWA qualifié est habilité à retirer le capot et à

démonter ou modifier l’instrument. Certains composants à l’intérieur de

l’instrument sont à haute tension et par conséquent, représentent un danger.

• Installer et utiliser l’instrument aux emplacements appropriés

• Ne pas installer, ni utiliser l’instrument à l’extérieur ou dans des lieux exposés

à la pluie ou à l’eau.

• Installer l’instrument de manière à pourvoir immédiatement le débrancher du

secteur en cas de fonctionnement anormal ou dangereux.

ATTENTION

Limitations relatives à l’environnement opérationnel

Ce produit est un produit de classe A (pour environnements industriels). L’utilisation

de ce produit dans un zone résidentielle peut entraîner une interférence radio que

l’utilisateur sera tenu de rectifier.
