3 Temperature
Measurement Point
¡
Installation environment
When using it,it is necessary to radiate heat by the heat of the pow-
er supply.
Table 3.1 - 3.8 shows the relation between the upper limit tempera-
ture (Point
1
and Point
2
) and load factors.
Please consider the ventilation so that the convection which is
enough for the whole power supply is provided.
Temperature of Point
1
and Point
2
become lower than upper limit
temperature.
The life expectancy in the upper bound temperature (Point
1
and
Point
2
) is three years or more.
Please refer to External View for the position of Point
1
and Point
2
.
Remarks:
*
Please be careful of electric shock or earth leakage in case of
temperature measurement, because Point
1
and Point
2
is
live potential.
*
Please contact us for details.
