Temperature and pressures of the cooling air
Important
y A cooling air feed above 40 °C can lead to power restrictions;
in extreme cases it can cause damage to the generator.
► The temperature of the supplied cooling air should not
exceed 40 °C.
y
A maximum underpressure of P
max
= 4 Pa is
allowed in the suction path of the cooling air,
otherwise, a sufficient quantity of cooling air
cannot be drawn in.
y
In the blow-out area of the cooling air on
the front side, a maximum overpressure of
P
max
= 7 Pa may arise as otherwise there will
not be sufficient circulation of the cooling air.
Important
y
An impaired cooling air current can
lead to restrictions in performance
damaging the generator.
►
Do not impair the circulation of
the cooling air with other air flows
(e.g. from the front or from the side).
