CAUTION
FOR CONTINUED PROTECTION AGAINST FIRE HAZARD,
V A REPLACE ONLY WITH FUSE OF SAME TYPE AND RATING INDICATED.
CAUTIONF ATTENTION
AFIN D'ASSURER UNE PROTECTION PERMANENTE CONTRE LES RISQUES D'INCENDIE,
V A REMPLACER UNIQUEMENT PAR UN FUSIBLE DE MEME TYPE ET CALIBRATION COMME INDIQUE.
THIS SYMBOL LOCATED NEAR THE FUSE INDICATES THAT THE FUSE USED IS SLOW OPERATING TYPE
FOR CONTINUED PROTECTION AGAINST FIRE FUSE HAZARD, REPLACE WITH SAME TYPE FUSE.
RATING REFER TO THE MAKING ADJACENT TO THE SYMBOL.
CE SYMBOLE INDIQUE QUE LE FUSIBLE UTLISE EST A LENT, E POUR UNEPROTECTION PERMANENT,
N'UTILISER QUE DES FUSIBLES DE MEME TYPE.
