INSTRUCTION MANUAL
PA640-04-01B
CAUTION ON USE
When used in environment with corrosive gas (hydrogen sulfide, sulfur dioxide, etc.) , there is possibility that they might penetrate the product and lead to
failure.
When used in environments where there is conductive foreign matter or dust, there is possibility of product failure or malfunction.
Provide countermeasure for prevention of lightning surge voltage as there is a risk of damage due to abnormal voltage.
Connect together the frame ground terminal of the product and the ground terminal of the equipment for safety and noise reduction. If these ground is not
connected together, there is a risk of electric shock.
Take care not to apply external abnormal voltage to the input/output. Especially, applying reverse voltage or overvoltage more than the rated voltage to the
input/output as it may cause failure, electric shock or fire.
Depending on product failure mode, there is possibility of hazardous voltage occurance at the input/output terminal. Therefore, the input/output of this
product must be protected in the end use equipment to maintain ES1.
This product contains a printed circuit board utilizing surface mounted devices. PCB stress such as bending, twisting, etc., could cause damage. Please handle
with care.
NOTE
When disposing product, follow disposal laws of each municipality.
Published EMI (RE) or immunity is the result when measured in our standard measurement conditions and may not satisfy specification when mounted and
wired inside end-user equipment.Use the product after sufficient evaluation is done at the actual end-user equipment.
When exporting our products, apply the necessary permissions as required by rules and regulations of Foreign Exchange and Foreign Trade Control Act.
Catalogue or contents of the instruction manual may be changed without a prior notice. Refer to latest catalogue or instruction manual.
Reproduction or reprinting the instruction manual or its portion is not allowed without our permission.
PRECAUTIONS DE MONTAGE ET D’UTILISATION
Respecter les connexions des borniers d’entrée/sortie décrites dans le manuel utilisateur avant de mettre sous tension.
Ne pas utiliser ce produit dans un environnement exposé à un fort champ émectromagnétique, à des substances corrosives ou conductrices,
à la lumière directe du soleil ou à la pluie et l’humidité.
En cas d’installation dans un environnement où des particules conductrices, de la poussière ou des liquides peuvent être présents,
merci d’installer des filtres afin de prévenir toute intrusion de corps étrangers à l’intérieur du produit et d’éviter pannes et dysfonctionnements.
Ce produit est destiné aux équipements électroniques à usage general et il n’est pas conçu pour des applications à hauts risques (telles que les applications de
sécurité ou de grande fiabilité. Même si une grande fiabilité ou une grande sécurité ne sont pas requises, ce produit ne doit pas être utilisé directement dans
des applications présentant des risques sérieux pour la vie ou l’intégrité physique). Le principe de défaillance sécuritaire doit être appliqué à la conception
(tels que l’installation de circuits ou de composants de protection).
Connecter la masse du châssis et la borne de terre de l’équipenet pour la sécurité et la réduction de bruit. Si cette connexion n’est pas faite, il existe un risque
de choc électrique.
En fonction du type de défaillance, il eixte un possibilité de pr »sence d’une tension dangereuse sur les bornes de sortie. Ainsi, la sortie de ce produit doit être
protégée dans l’équipement final pour conserver la TBTS.
LONG-TERM STORAGE METHOD AND LONG-TERM STORAGE PERIOD
Please keep the product in carton box.
Please do not apply excessive vibration, shock or mechanical stress applied directly to the product.
Please keep away from direct sunlight.
Temperature and humidity should be within range of product specification (with no condensation)
For long-term storage temperature and humidity, the following conditions shall be used as a guideline :
Temperature range : 5℃
～
30℃
Humidity range : 40%
～
60%RH
Please keep away from the places where temperature and humidity can change drastically
It can cause condensation on the product or deterioration.
For long-term storage period, we recommened to use within 2 years after receiving the product.
There is tendency that the leakage current of the aluminium electrolytic capacitors may increase over time when stored without using for long time.
This phenomenon can be improved by applying voltage to the aluminium electrolytic capacitors in order to reduce the increased of leakage current through
the self-recovery effect of the electrolyte.
For reference, before using products that have been stored for a long time, please warm-up first for 30 minutes or more without taking load.
