Installation of generator
Installation of dual-bearing generators (BG 132)
Cooling
Observe the following instructions
for the cooling of the generator
.
Risk of overheating.
The temperature of the supplied cooling air
should not exceed 40 °C.
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.
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).
