DANGER
HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
·
While removing or installing panels and
covers, assure that they do not contact an
energized bus.
·
NEVER bypass external fusing.
·
NEVER short the secondary of a potential
transformer.
·
Before closing covers and doors, carefully
inspect the work area and remove any tools,
wire scraps or other objects that may have
been left inside the equipment.
Failure to follow these instructions will result in
death or serious injury.

DANGER
RISQUE DE CHOC ÉLECTRIQUE,
EXPLOSION OU ARC FLASH
·
Lors du retrait ou de l’installation des pan-
neaux et des capots, assurez-vous qu’ils ne
touchent pas un bus sous tension.
·
NE JAMAIS contourner la recherche externe.
·
NE JAMAIS court-circuiter le secondaire d’un
transformateur de potentiel.
·
Avant de fermer les capots et les portes,
inspectez soigneusement la zone de travail et
retirez les outils, bouts de fil ou autres objets
éventuellement restés à l’intérieur de l’équi-
pement.
Si ces précautions ne sont pas respectées, cela
entraînera la mort ou des blessures graves.
The Core Module must be connected to the volt-
age source being monitored. The Voltage Input
terminal serves as the both power source to the
monitor and voltage sensing. All phases that are
to be monitored must be connected. The current
consumption of the monitor will not exceed 0.2 A
at any operational voltage.
The monitor is fused internally but additional
fusing may be required per local and national
codes
. Inline fuses are available from Janitza.
