SEL-734 Meter Instruction Manual Date Code 20090730
Equipment components are sensitive to electrostatic discharge
(ESD). Undetectable permanent damage can result if you do
not use proper ESD procedures. Ground yourself, your work
surface, and this equipment before removing any cover from
this equipment. If your facility is not equipped to work with
these components, contact SEL about returning this device and
related SEL equipment for service.
!
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.
!
CAUTION
Use of controls or adjustments, or performance of procedures
other than those specified herein, may result in hazardous
radiation exposure.
!
CAUTION
Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to
operate the equipment.
!
CAUTION

access.
!
WARNING
Les composants de cet équipement sont sensibles aux
décharges électrostatiques (DES). Des dommages permanents
non-décelables peuvent résulter de l’absence de précautions
contre les DES. Raccordez-vous correctement à la terre, ainsi
que la surface de travail et l’appareil avant d’en retirer un
panneau. Si vous n’êtes pas équipés pour travailler avec ce type
de composants, contacter SEL afin de retourner l’appareil pour
un service en usine.
!
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 recommandé par le fabricant. Se
débarrasser des piles usagées suivant les instructions du
fabricant.
!
ATTENTION
L’utilisation de commandes ou de réglages, ou l’application de
tests de fonctionnement différents de ceux décrits ci-après
peuvent entraîner l’exposition à des radiations dangereuses.
!
ATTENTION
Les changements ou modifications qui ne sont pas
expressément approuvés par l'autorité responsable de se
prononcer sur la conformité pourraient annuler le pouvoir de
l'usager à actionner l'équipement.
!
ATTENTION
Débrancher tous les raccordements externes avant d’ouvrir cet
appareil. Tout contact avec des tensions ou courants internes à
l’appareil peut causer un choc électrique pouvant entraîner des
blessures ou la mort.
!
DANGER
Tout contact avec les bornes de l’appareil peut causer un choc
électrique pouvant entraîner des blessuers ou la mort.
!
DANGER
Seules des personnes qualifiées peuvent travailler sur cet
appareil. Si vous n’êtes pas qualifiés pour ce travail, vous
pourriez vous blesser avec d’autres personnes ou endommager
l’équipement.
!
AVERTISSEMENT
L'utilisation de cet appareil suivant des procédures différentes
de celles indiquées dans ce manuel peut désarmer les
dispositifs de protection d'opérateur normalement actifs sur
cet équipement.
!
AVERTISSEMENT
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 accés non-autorisé á l’équipement peut être
possible. SEL décline toute responsabilité pour tout dommage
résultant de cet accés non-autorisé.

SEL-734 Meter Forms and Models
This instruction manual covers the following SEL-734 Meter Forms and
Models.
Model numbers are derived from the SEL-734 Model Option Table. For the
available options, associated option codes, or to order an SEL-734, refer to the
Model Option Table for this product at the SEL website.
The SEL-734 offers two options for current classes, CL10 or CL20. The
internal hardware of the SEL-734 is identical for both classes. Therefore, a
CL10 meter will meter accurately up to the CL20 meter rating of 20 amps.
The only difference between an SEL-734 CL10 and CL20 is the configuration
label on the front panel. SEL recommends using a CL20 meter unless a
specification calls for a CL10 meter.
Throughout this manual, meter model 0734ES2-6X (Expansion Slot #2 = 6X)
and model 0734ES2-8X (Expansion Slot #2 = 8X) are used to show the
difference from model 0734ES2-XX (Expansion Slot #2 = XX) when
necessary for discussion. The only difference is that meter models
0734ES2-6X and 0734ES2-8X have an extra I/O board (see Figure 2.6).
Meter models 0734ES1-XX and 0734ES1-2X show the difference between an
empty expansion slot #1 and slot #1 with an optional communications card.
