f) Damp or very dry locations, radiant heat, vermin infestation, or atmospheres conducive to fungus
growth
g) Abnormal shock, vibration or mechanical loading from external sources during equipment operation
h) Abnormal axial or side thrust imposed on rotating equipment shafts
i) Low and/or high ambient temperatures
j) High electromagnetic fields
2) Operation at:
a) Voltages above or below rated voltage
b) Speeds other than rated speed
c) Frequency other than rated frequency
d) Standstill with rotating equipment windings energized
e) Unbalanced voltages
f) Operation at loads greater than rated
3) Operation where low acoustical noise levels are required
