This symbol is intended to alert
the user to the presence of
uninsulated “dangerous voltage”
within the product’s enclosure
that may be of sufcient
magnitude to constitute a risk
of electric shock to persons.
Ce symbole a pour but d’attirer l’attention de l’utilisateur sur la présence, à
l’intérieur du boîtier de l’appareil, d’une « tension dangereuse » non isolée, qui
pourrait être sufsamment puissante pour représenter un risque d’électrocution
pour les personnes.
This symbol is intended to
alert the user to the presence
of important operating and
maintenance (servicing)
instructions in the literature
accompanying the appliance.
Ce symbole a pour but d’attirer l’attention de l’utilisateur sur la présence, dans la
