WARNING
The opening of the branch-circuit protective device may be an
indication that a fault has been interrupted. To reduce the risk of fire
or electric shock, current-carrying parts and other components of the
controller should be examined and replaced if damaged.
For Canadian installations
AVERTISSEMENT
L‘ouverture du dispositif de protection de la dérivation peut signifier
qu‘un courant de défaut a été interrompu. Pour réduire le risque
d‘incendie ou de choc électrique, les pièces porteuses de courant
et autres composants du contrôleur devraient être examinées et
remplacées s‘ils sont endommagés.
