*1 The performance values are based on IEC60068-3-5:2001 and IEC60068-3-6:2001;
Performance figures are given for a +23°C ambient temperature, relative humidity of 65±20%rh, rated voltage, and no specimen inside the test area.
*2 When temperature is stable, the cleanliness is according to JIS B9920:2002 (equivalent to FED-STD-209D Class 100).
The Class 5 cleanliness cannot be maintained when the door is open. Do not open the door when operating at temperatures below 0°C
*3 Excluding protrusions. Dimension indicated in ( ) includes protrusion.
