Comments
No other parts were observed to create any hazard due to temperature rise.
P
*) Temperature rise limits for Singapore is 10K less.
**) Directly covering part for heat-sink. The top cover is supplied with ventilation openings
covering most of the top cover. This indicate emission of heat from internal parts and the
opening area is therefore not likely to be touched during normal use. Based on this the
temp. rise is accepted also for tropical climates.
