RISK OF ELECTRICAL SHOCK, DC
An OFF Battery Switch / Breaker does not isolate the batteries, nor do the batteries have a protective fuse. Thus, handle
accordingly and use only insulated tools when working around batteries or any DC potential.
In addition, be sure that all connection points have been de-energized.
GMT fuses can produce sparks during interruption or clearing of a fault, so only use Bussman GMT fuses provided with safety
caps.
