Normal use and installation conditions

Normal use conditions

Ambient air temperature

Ambient air temperature shall not be more than +55℃ and not less than -20℃ and the Altitude of the installation place shall not exceed 2000m.

Atmospheric conditions

Humidity

The relative air humidity at installation place shall not be more than 50% when the ambient air temperature is +40℃; Relative humidity may be high under low temperature condition. For instance, when the mean minimum temperature in the wettest month is +20℃, the mean maximum relative humidity in the month may reach 90%. Condensation produced due to temperature change shall be prevented by taking appropriate measure.

Protector can be vertically or horizontally mounted in cabinet. If specially required, it is necessary to make special order.

Protector shall be mounted in medium without risk of explosion. In the medium, there shall be no gas and conductive dust which are sufficient to corrode metal and affect insulation effect.

Protector shall be mounted in place that may not be invaded by rain and snow.
