Battery Safety 0
WARNING: A battery can present a risk of electrical shock or burn from large
amounts of short-circuit current, fire, or explosion from vented gases. Observe
proper precautions.
WARNING: Risk of Explosion. Proper disposal of batteries is required. Do not
dispose of batteries in fire. Refer to local regulations or codes for requirements.
CAUTION: When replacing batteries, use properly specified number, sizes,
types, and ratings based on application and system design.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful
to skin, and may be toxic.
● Servicing of batteries should be performed, or supervised, by personnel
knowledgeable about batteries, and the proper safety precautions.
● Be very careful when working with large lead-acid batteries. Wear eye protection
and have fresh water available in case there is contact with the battery acid.
● Remove watches, rings, jewelry and other metal objects before working with
batteries.
● Wear rubber gloves and boots.
● Use tools with insulated handles and avoid placing tools or metal objects on top of
batteries.
● Disconnect charging source prior to connecting or disconnecting battery terminals.
● Determine if battery is inadvertently grounded. If so, remove the source of contact
with ground. Contact with any part of a grounded battery can result in electrical
shock. The likelihood of such a shock can be reduced if battery grounds are
removed during installation and maintenance (applicable to equipment and remote
battery supplies not having a grounded supply circuit).
● Carefully read the battery manufacturer's instructions before installing / connecting
to, or removing batteries from, the MPPT.
● Be very careful not to short circuit the cables connected to the battery.
● Have someone nearby to assist in case of an accident.
● Explosive battery gases can be present during charging. Be certain there is
enough ventilation to release the gases.
● Never smoke in the battery area.
● If battery acid comes into contact with the skin, wash with soap and water. If the
acid contacts the eye, flood with fresh water and get medical attention.
● Be sure the battery electrolyte level is correct before starting charging. Do not
attempt to charge a frozen battery.
● Recycle the battery when it is replaced.
