Measure the discharge time of
the main circuit capacitor when
the main power supply is shut of
f
and calculate the capacity of the
main circuit capacitor
.
It is judged that the end of life
has been reached when capacity
has reached 85% of the factory
default capacitor capacity or the
main circuit capacitor capacity
(pre-measured at startup) in a
user normal operation state.

Can be disabled by Protection/

lection (3008Hex-63Hex).
The time during which voltage is
applied to the main circuit capac-
itor (the time during which the
main power supply is ON) is
counted. Also, the time is cor-
rected by measuring the capacity
of the main circuit capacitor.
When the operation time ex-
ceeds 87,000 hours (10 years)

,
it is judged that the end of life
has reached.
