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: This procedure requires that you

handle components sensitive to Electrostatic

Discharge (ESD). If your facility is not equipped

to work with these components, we recommend

that you return the relay to SEL for firmware

installation.

ATTENTION: Cette procédure requiert que

vous manipuliez des composants sensibles aux

décharges électrostatiques (DES). Si vous n'êtes

pas équipés pour travailler avec ce type de

composants, nous vous recommandons de les

retourner à SEL pour leur installation.

CAUTION: Verify proper orientation of any

replaced Integrated Circuit(s) (ICs) before

reassembling the relay. Energizing the relay with

an IC reversed irrecoverably damages the IC. If

you mistakenly reenergize the relay with an IC

reversed, do not place the relay in service using

that IC, even if you correct the orientation.

ATTENTION: Vérifier l'orientation d’un circuit

intégré (CI) que vous remplacez avant de l’

installer sur le relais. La mise sous-tension du

relais avec un CI inversé endommagera de façon

irréversible celui-ci. Si vous remettez le relais

sous tension par mégarde, ne pas laisser le relais

en service avec ce CI, même si l'orientation a été

corrigée.

CAUTION:Never work on the SEL-321 with

the front or top cover removed, when the SEL-321

is energized.

ATTENTION: Ne jamais travailler sur le

SEL-321 avec le panneau avant ou du dessus

enlevé, quand le SEL-321 est sous-tension.

WARNING: Do not rely upon pins 5 and 9 for

safety grounding, because their current-carrying

capacity is less than control power short circuit

and protection levels

AVERTISSEMENT: Ne pas se fier aux broches

5 et 9 pour une mise à la terre sécuritaire: leur

limite de support en courant est inférieure au

niveau de court-circuit assuré par la protection.

WARNING: Use only serial communications

cables manufactured by SEL or built to SEL

specifications with the SEL-321 Relay. Damage

to the relay or your communication equipment

may result from the use of incorrect

communication connections.

AVERTISSEMENT: N’utiliser que des câbles

de communication série produits par SEL ou

conformes à ses spécifications avec le relais

SEL-321. Des dommages au relais ou à

l’équipement de communication pourraient

survenir à la suite de mauvais raccordements.

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-autorisé à

l'équipement pourrait être possible. SEL décline

toute responsabilité pour tout dommage résultant

de cet accès non-autorisé.

SEL-321/321-1 Instruction Manual

PREFACE

This manual applies to multiple versions of the SEL-321 and SEL-321-1 Relays (designed to

operate with nominal system frequencies of 50 Hz and 60 Hz). Except when specific differences

are noted, all specifications and data apply equally to all versions of the relay.

SEL-321 RELAY VS SEL-321-1 RELAY

Throughout this manual where there are differences between the SEL-321 Relay and the

SEL-321-1 Relay the headings of those sections that apply strictly to the SEL-321-1 Relay

include the following statement:
