Total Power ON Time
Monitor
0 to 655350 hours
The cumulative operation time (the time when
the main power supply is ON) of the inverter
is displayed.
Measurement range: 0 to 655,350 hours
Display: The cumulative operation time is dis-
played alternately in the upper digits and low-
er digits.
Example 0 <=> 535h (535 hours)
655 <=> 350h (655,350 hours)
When the lower three digits are displayed, an
h (hours) is displayed in the lowermost digit.
When 655,350 hours is reached, it is consid-
ered as the upper limit.

Main circuit DC volt-
age Monitor
0.0 to 999.0 [V]
The Main Circuit DC Voltage of the inverter is
displayed.
Although the display is in increments of 0.1 V
,
the data changes in increments of 1 V.

Internal Air Highest
Temperature
20 to 125 [°C]
The maximum value of the internal air tem-
perature for each hour is displayed in incre-
ments of 1 degree.
Display unit: °C (for 20°C and below, 20°C is
displayed.)
Since there is no internal air temperature sen-
sor in 15kW and lower models, “----” is dis-
played. 0 is displayed in W72.

100.0 to 999.9 [A]
The maximum effective current value for each
hour is displayed.
Display unit: Displayed in increments of 0.01
A for 100 A or below
,
and in increments of 0.1 A for above 100 A
