Connection hardware
tightness is less than
the specified
retorque value.
Repetitive cycles
resulting in heating
and cooling of
connection can
result in relaxation of
torque and an
increase in
connection
resistance.
Loose connections can
result in heat damaged
or melted terminals
during high rate
discharge.
Retorque the
connection
as required.
