5.6.3 Assembly (iMAPLA 25and 30)
During assembly, observe the minimum clearances and specications for
cooling in the following chapter.
Generator dimensions
Ö Minimum clearances and cooling provisions, page82
Secure the generator with at least four mounting
screws (minimum M12or comparable, bolt grade
min.8.8). The attachment must be permanent
and resistant to shock and vibrations. Use
suitable means to prevent the screws from
coming undone by themselves, e.g.via atension
ring according to DIN 128.
y Tightening torque for mounting screws: M=
87Nm
y Permissible load of the shaft: Fr
max
= 5,000N
(measured in 60mm axial clearance from the
point where the shaft exits the bearing plate)
Fa
max
= 500N
Important
► Do not attach any third party parts to
the mounting proles on the generator
housing.
5.6.4 Minimum clearances and cooling provisions
y The generator needs sucient ventilation for cooling. The cooling air is
drawn through the cooling proles by the fan wheel on the rear side of the
generator and across the housing, towards the front side.
y Ensure adequate air feed and exhaust openings.
y Comply with the following minimum clearances and note the regulations
for cooling.
