WARNING:
RISK OF ELECTRICAL SHOCK.
NO POWER OR ACCESSORY TERMINALS ARE ELEC-
TRICALLY ISOLATED FROM DC INPUT, AND MAY BE ENER-
GIZED WITH HAZARDOUS SOLAR VOLTAGE. UNDER CERTAIN
FAULT CONDITIONS, BATTERY COULD BECOME OVER-
CHARGED. TEST BETWEEN ALL TERMINALS AND GROUND
BEFORE TOUCHING.
AVERTISSEMENT:
RISQUE DE CHOC ÉLECTRIQUE.
NON ALIMENTATION OU AUX BORNES
D'ACCESSOIRES SONT ISOLÉS ÉLECTRIQUEMENT DE
L'ENTRÉE DE C.C ET DOIT ÊTRE ALIMENTÉS À UNE TENSION
DANGEREUSE SOLAIRE. SOUS CERTAINES CONDITIONS DE
DÉFAILLANCE, LA BATTERIE POURRAIT DEVENIR TROP CHAR-
GÉE. TEST ENTRE TOUTES LES BORNES ET LA MASSE AVANT
DE TOUCHER.
