Thefollowingsymbolsareusedthroughoutthismanualto indicatepotentiallydangerousconditionsormarkimportantsafety instructions: NOTE: PROPER DISPOSAL OF BATTERIES IS REQUIRED. REFER TO YOUR LOCAL CODES FOR DISPOSAL REQUIREMENTS; WARNING: Indicates a potentially dangerous condition. Use extreme caution when performing this task.
! ATTENTION: UNE BATTERIE PEUT PRÉSENTER UN RISQUE ÉLEVÉ DE CHOC ÉLECTRIQUE, DE BRÛLURES SUITE À UN COURANT DE COURT-CIRCUIT ÉLEVÉ, À UN INCENDIE OU À UNE EXPLOSION PROVENANT DE GAZ REJETÉS DANS L’AIR. VEUILLEZ PRENDRE LES PRÉCAUTIONS NÉCESSAIRES. AVERTISSEMENT: Ces instructions d’entretien sont exclusivement réservées à des techniciens qualifiés.
AVERTISSEMENT: L’appareil n’est pas fourni avec un dispositif GFDI. Ce contrôleur de charge doit être utilisé avec un dispositif GFDI externe tel que requis par l’Article 690 du Code électrique national de l’emplacement de l’installation. 2.1 Overview ThankyouforselectingtheSunSaversolarcharge controller.TheSunSaverisanadvancedPWMsolarbattery chargerandloadcontrollerforstand-alonePVsystems.

3.3 Mounting ! CAUTION: Equipment Damage When installing the SunSaver in an enclosure, ensure sufficient ventilation. Installation in a sealed enclosure will lead to over-heating and a decreased product lifetime. ! PRUDENCE: Endommagement de l’équipement ou risque d’explosion N’installez jamais le SunSaver dans une enceinte avec des batteries à évent/à électrolyte liquide. Les vapeurs des batteries sont inflammables et corroderont et détruiront les circuits du SunSaver.
3.4 Wiring NOTE: A recommended connection order has been provided for maximum safety during installation. The controller will not be damaged regardless of the sequence of connections. SUNSAVER-20L CHARGING STATUS Nominal Rating 12 Volts dc Max. Input 30 V Solar 20.0 A Battery 20.0 A Load 20.0 A Max. Ambient 65 ºC ! NOTE: To comply with the NEC, the SunSaver must be installed using wiring methods in accordance with Article 690 of the latest edition of the National Electric Code, NFPA 70.
Step 2: Battery Wiring WARNING: Shock Hazard Fuses, circuit breakers, and disconnect switches should never open grounded system conductors. Only GFDI devices are permitted to disconnect grounded conductors. NOTE: Battery circuit fuse / breaker not included. Fuse must be purchased separately.
