be observed and measured.
The value shown on this monitor should be equal to or less than 100% for optimum
operating conditions.
If this value is over 100%, one of the following measures must be taken to ensure
safe operation and a long product life.

To improve the air circulation to meet these minimum standards and to lower the per-

the temperature of the surrounding air.

For every increase of 10°C, the percentage shown on the monitor will also increase
