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 (DES).

Quand on travaille sur le relais avec le panneau avant

ou du dessus enlevé, les surfaces de travail et le

personnel doivent être mis à la terre convenablement

pour éviter les dommages à l'équipement.

CAUTION: There is danger of explosion if the

battery is incorrectly replaced. Replace only with

Ray-O-Vac®no. BR2335 or equivalent

recommended by manufacturer. Dispose of used

batteries according to the manufacturer’s

instructions.

ATTENTION: Il y a un danger d’explosion si la

pile électrique n’est pas correctement remplacée.

Utiliser exclusivement Ray-O-Vac®No. BR2335 ou

un équivalent recommandépar le fabricant. Se

débarrasser des piles usagées suivant les instructions

du fabricant.

CAUTION: The continuous rating of the current

inputs is 3 ·Inom. If any currents in this test will

exceed this rating, reduce the TAPn values as

needed, to prevent possible damage to the input

circuits.

ATTENTION: La capacité, en régime permanent,

des entrées de courant est 3 ·Inom. Si un courant

d’essai dépassait cette valeur, réduire la prise TAPn

pour prévenir les dommages aux circuits d’entrée.



CAUTION: The continuous rating of the current

inputs is 3 ·Inom. For this test, you may want to

choose low values of U87P and TAPn, in order to

limit the required test current to a safe value.



ATTENTION: La limite, en régime permanent, des

entrées de courant est 3 ·Inom. Pour ce test, vous

pourriez choisir de valeurs peu élevées pour U87P et

TAPn, de façon àlimiter le courant de test àune

valeur sécuritaire.

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.

AVERTISSEMENT: Cet équipement 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-autoriséàl'équipement

pourrait être possible. SEL décline toute

responsabilitépour tout dommage résultant de cet

accès non-autorisé.

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 àla

circuiterie qui pourrait être la source de chocs

électriques 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.
