 Servicing of batteries, battery modules and battery cabinet must be performed or
supervised by qualified service personnel knowledgeable in batteries, battery
modules and the battery cabinet as well as their required precautions. Keep
unauthorized personnel away from batteries, battery modules and the battery
cabinet.
 A battery can present a risk of electric shock and high short-circuit current.
 To reduce the risk of fire or electric shock, install the battery modules in a
temperature and humidity controlled indoor area free of conductive contaminants.
 Forbid opening or removing the chassis of both battery modules and Battery
Cabinet to avoid high voltage electric shock.

the battery source.
