WARNING
o Remove rings, bracelets, wristwatches, and neck
chains before working around the locomotive.
Jewelry can catch on equipment and cause injury,
or may short across an electrical circuit and cause
severe burns or electrical shock.
o High voltage is used in the operation of
equipment. Do not be misled by the term LOW
VOLTAGE. Potentials as low as 50 volts may cause
death.
o Be careful not to short out battery terminals. Do
not smoke or use open flame near batteries.
Batteries may explode from a spark. Battery acid is
harmful to skin and eyes.
CAUTION
Keep vent plugs in place. Do not allow soda
solution to get into the cells. It will neutralize the
electrolyte and lower cell capacity.
NOTE
This system is a 64-volt system consisting of eight storage batteries.
