CHAPTER11 MAINTENANCE AND INSPECTION
DANGER
Do not touch the terminals while power is on.
Doing so could cause shock or erroneous operation.
Correctly connect the battery.
Also, do not charge, disassemble, heat, place in fire, short circuit,
or solder the battery.
Mishandling of battery can cause overheating or cracks which
could result in injury and fires.
Turn off all phases of the external supply power used in the system
when cleaning the module or retightening the terminal block
mounting screws, terminal screws, or module fixing screws.
Not doing so could result in electric shock.
Tighten a terminal block mounting screw, terminal screw, and
module fixing screw within the specified torque range.
If the terminal block mounting screw or terminal screw is too loose,
it may cause a short circuit, fire, or malfunctions.
If too tight, it may damage the screw and/or the module, resulting
in a drop of the screw or module, a short circuit or malfunctions.
If the module fixing screw is too loose, it may cause a drop of the
screw or module.
Over tightening the screw may cause a drop due to the damage of
the screw or module.
