Instruction Manual

DANGER: Contact with instrument
terminals may cause electrical shock
which can result in injury or death.
!
DANGER: Tout contact avec les bornes de
raccordement de l’appareil peut causer un
choc électrique pouvant entraîner des
blessures ou la mort.
!
DANGER: Contact with this circuitry
may cause electrical shock that can result
in injury or death.
!
DANGER: Tout contact avec ce circuit peut
être la cause d’un choc électrique pouvant
entraîner des blessuers ou la mort.
!
WARNING: Overtightening the
mounting nuts may permanently
damage the monitor chassis.
!
ATTENTION: Une pression excessive sur
les écroux de montage peut endommager
de façon permanente le chassis l’appareil de
surveillance.
!
WARNING: Be sure to carefully align
the front panel with the monitor chassis
during reassembly. If the front panel is
not well aligned with the chassis, you
may bend connector pins, causing the
monitor to fail.
!
ATTENTION: Assurez-vous d'aligner
soigneusement le panneau frontal avec le
châssis l’appareil de surveillance en cours de
remontage. Si le panneau n'était pas bien
aligné avec le châssis, vous pourriez plier les
broches du connecteur, entraînant une
pannel’appareil de surveillance du relais.
!
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.
!
ATTENTION: Assurez-vous d'aligner
soigneusement le panneau frontal avec le
châssis du relais en cours de remontage. Si
le panneau du relais n'était pas bien aligné
avec le châssis, vous pourriez plier les
broches du connecteur, entraînant une
panne du relais.
!
!
CAUTION: Do not connect external
voltages to the monitor contact inputs.
Because the contact inputs are internally
wetted, permanent damage to the
monitor or external equipment may
result from connecting external voltage
to a monitor contact input.
ATTENTION: Ne pas raccorder de tensions
externes sur les bornes des entrées de contact
de l’appareil de surveillance. Parce que les
contacts sont trempés au mercure, des
dommages permanents peuvent résulter pour
l’appareil de surveillance ou l’équipement
externe à la suite du raccordement d’une
tension externe à une entrée de contact.
!
CAUTION: The monitor contains
devices sensitive to Electrostatic
Discharge (ESD). When working on the
monitor with the front panel removed,
work surfaces and personnel must be
properly grounded or equipment
damage may result.
!
ATTENTION: L’appareil de surveillance
contient des pièces sensibles aux décharges
électrostatiques. Quand on travaille sur lui,
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.
!
CAUTION: Removal of enclosure
panels exposes circuitry which may
cause electrical shock which can result in
injury or death.
!
ATTENTION: Le retrait des panneaux du
boîtier expose le circuit qui peut causer des
chocos électriques pouvant entraîner des
blessures ou la mort.
