Safety Instructions
WARNING:
DC input power to the inverter is normally from a battery
bank with a very high short-circuit capacity. Accidental
welding and severe burns can be caused by mistakes while
connecting or disconnecting these conductors.

ATTENTION
L'entrée DC de l'onduleur est normalement alimentée par une
batterie avee un courant de court-circuit élevé. Une erreur
lors de la connexion ou deconnexion de ces conducteurs
peut causer des soudures accidentelles et des brûlures
sérieuses.

IMPORTANT SAFETY INSTRUCTIONS FOR SERVICING BATTERIES
A.
Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and the
required precautions. Keep unauthorized personnel away from batteries.
B.
When replacing batteries, use the same model and manufacturer of batteries.
C. CAUTION — Do not dispose of battery or batteries in a fire. The battery may explode.
D. CAUTION — Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.
E.
CAUTION — A battery can present a risk of electrical shock and high short-circuit current. The following precau-
tions should be observed when working with batteries:
1.
Remove watches, rings, or other metal objects.
2.
Use tools with insulated handles.
3.
Wear rubber gloves and boots.
4.
Do not lay tools or metal parts on top of batteries.
5.
Disconnect charging source prior to connecting or disconnecting battery terminals.
6.
Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the source of ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock will
be reduced if such grounds are removed during installation and maintenance.
