Comments
No other parts were observed to create any hazard due to temperature rise.
P
*) Temperature rise limits for Singapore is 10K less.
P
**) Directly covering part for heat-sink and transformer. 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.
