Installation and commissioning
Generator installation for iMAPLA 25and 30
Important
► The drive belt must not sag
loosely.
When using narrow belt pulleys of type SPA, the
clearance between the axes must not exceed
800mm. For permissible axis clearances for other
belts, ask the manufacturer.
Note
► For narrow Vbelts/V-belts of type XPB, a2x belt is needed for
the iMAPLA 25and 30systems.
Maximum tension force (tension) of the drive belt on the shaft
F
max
= 5,000N at amax. 60mm axial clearance
from the point where the shaft exits the bearing
plate. The belt tension must not exceed aradial
force of 5,000N at amax. axial clearance of
60mm from the point where the shaft exits the
bearing plate. If the belt pulley attachment to the
shaft is placed further out, reduce the tension of
the belt accordingly in order to balance out the
increased leverage eect on the shaft.
