WARNING: This device is shipped with default

passwords. Default passwords should be changed to

private passwords at installation. Failure to change each

default password to a private password may allow

unauthorized access. SEL shall not be responsible for

any damage resulting from unauthorized access.

ADVERTISSEMENT: Cet appareil est expédié avec des mots

de passe par défaut. A l'installation, les mots de passe par

défaut devront être changés pour des mots de passe

confidentiels. Dans le cas contraire, un accès non-autorisé à

l'équipement pourrait être possible. SEL décline toute

responsabilité pour tout dommage résultant de cet accès non-

autorisé.

CAUTION: Be sure to follow the generator and prime

mover manufacturers’ guidelines with respect to

generator operation and commissioning.

!ATTENTION: Suivez attentivement les instructions des

manufacturiers de la turbine et de la génératrice pour la

réception, la mise en route et l'opération.

CAUTION:Do not apply reverse polarity dc voltage or ac

voltage to terminals Z25 and Z26 of SEL-300G Relays

rated for 24/48 Vdc applications. Relay failure and

permanent power supply damage will result from

application of reverse polarity dc voltage to relays rated

for 24/48 Vdc applications.

ATTENTION: N’appliquer pas un voltage CC avec polarité

inversée ou un voltage CA, sur les bornes Z35 et Z26 des relais

300G dont la tension d’alimentation nominale est 24/48 VCC.

Une perte de fonctionnement du relais et un bris permanent de

l’alimentation résulteraient de l’application d’une polarité CC

inversée sur un relais avec tension nominale de 24/48 VCC.

CAUTION: Standard SEL relay output contacts are rated

to make and carry trip coil current, but are not rated to

interrupt trip coil current. Do not exceed the contact

interrupt ratings shown in Relay Specifications and

Options.

ATTENTION: Les contacts standards des relais SEL ont la

capacité de fermer sur le courant spécifié des bobines

d’ouverture mais ne peuvent ouvrir sur le même courant. Il est

important de ne pas dépasser les capacités des contacts

indiquées an paragraphe Spécifications du Relais et

Options.

CAUTION: The relay contains devices sensitive to

electrostatic discharge (ESD). When working on the

relay with front or top cover removed, work surfaces and

personnel must be properly grounded or equipment

damage may result.

ATTENTION: Le relais contient des pièces sensibles aux

décharges électrostatiques. Quand on travaille sur le relais

avec les panneaux avant ou du dessus enlevés, toutes les

surfaces et le personnel doivent être mis à la terre

convenablement pour éviter les dommages à l'équipement.

DANGER: Removal of relay front panel exposes circuitry

which may cause electrical shock that can result in injury

or death.

DANGER: Le retrait du panneau avant expose à la circuiterie

qui pourrait être la source de chocs électriques pouvant

entraîner des blessures ou la mort.

DANGER: Contact with this circuitry may cause

electrical shock that can result in injury or death.

DANGER: Le contact avec la circuiterie peut causer un choc

électrique pouvant entraîner des blessures ou la mort.

DANGER: Contact with instrument terminals may cause

electrical shock which can result in injury or death. !

DANGER: Le contact avec les bornes de l' instrument peut

causer un choc électrique pouvant entraîner des blessures ou la

mort.
