The following general battery safety precautions and warnings must be observed at all times:
•
A battery can present risk of electric shock or burn from high short circuit currents.
•
When connected in a string, the voltage will exceed 400VDC. This voltage is potentially lethal.
Always observe high-voltage precautions.
•
Eye protection must be worn to prevent injury from accidental electrical arcs.
•
Remove rings, watches, necklaces, bracelets and all other metal objects.
•
Use only tools with insulated handles.
•
Wear appropriate personal protective equipment when handling batteries.
