Installation of generator
Installation of dual-bearing generators (BG 160)
6.8.2 Minimum clearances and cooling provisions
The generator needs sufficient ventilation for cooling. The cooling air is
drawn through the cooling profiles by the fan wheel on the rear side of the
generator and across the housing, towards the front side. Ensure adequate
air feed and exhaust openings. During assembly, observe the minimum
clearances and specifications for cooling.
Minimum clearances (BG 160)
When installing, respect the following
minimum clearances from fixed parts or walls.

In individual cases, the clearances may vary
from these figures. Get in touch with

Cooling (BG 160)
During assembly, observe the minimum
clearances and specifications for cooling.
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.
Do not impair the circulation of the cooling air
with other air flows (e.g. from the front or from
the side).
