!

ATTENTION: 

Pour diminuer le risque d’incendie, ne connectez 

l’alimentation qu’à un circuit équipé d’une protection 

maximum par dérivation contre les surintensités ne 

dépassant pas le courant nominal du modèle de la 

page 2, conformément à la norme du Code National de 

l’Électricité (NEC), ANSI/NFPA 70.

                        ATTENTION:

                        Unité bénéficie d’aucune protection de retrait de batterie.

                        Débrancher la batterie pendant la charge peut entraîner  

 

      un bref pic de tension de charge (au-dessus du 15V limite     

                        de règlement) qui peuvent endommager les équipement  

                        sensibles.

Installation Safety Precautions

WARNING:  

This unit is not provided with a GFDI device. This 

charge controller must be used with an external

elements and do not allow water to enter the controller.

•  Install the SunSaver in a location that prevents casual 

contact. The SunSaver heatsink can become very hot during 

operation.

•  Use insulated tools when working with batteries.
•  Avoid wearing jewelry during installation.
•  The battery bank must be comprised of batteries of same 

type, make, and age.

•  Do not smoke in the vicinity of the battery bank.
•  Mount the controller at least 3 ft (1 m) away from vented    

batteries unless separated by a barrier or located in a     

separate compartment.
