GenStar MPPT
• The battery bank must be comprised of batteries of same type, make, and age.
• Certified for use in negative ground systems, or positive ground with floating array
• Do not smoke near the battery bank.
• Power connections must remain tight to avoid excessive heating from a loose connection.
• Use properly sized conductors and circuit interrupters.
• The grounding terminal is located in the case, and is identified by the symbol below:
Ground
Symbol
• This charge controller is to be connected to DC circuits only. These DC connections are identi-
fied by the symbol below:
Direct Current Symbol
A means of disconnecting all power supply poles must be provided. These disconnects must be
incorporated in the fixed wiring.
The GenStar MPPT negative power terminals are common, and must be grounded as instructions,
local codes, and regulations require.
A permanent
,
reliable earth ground must be established with connection to the GenStar MPPT
ground terminal.
The grounding conductor must be secured against any accidental detachment.
• 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 likeli-
hood of such a shock can be reduced if battery grounds are removed during installation and
maint enance (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 GenStar 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.
