If the maximum operational ambient temperature cannot be measured at a point 10 mm away from the nameplate, a substitution method is stipulated in the table below. Measurement point Ambient temperature Temperature at cover (Point A) (Point A) 60°C 65°C 5°C 5°C *2: In case of the maximum wet bulb 40°C , the drive should be packed in HDD package box with ESD bag and desiccant. Please see specification 5.1 Packing for reference. If the drive is not packed in the HDD package box with ESD bag and desiccant, maximum wet bulb 29°C is applied. K6610170 Rev.2 Dec 22, 2004 - 16 -
