Auxiliary drive unit

For certain applications the gear unit can, in addition to the main drive unit, be equipped with an auxiliary
drive unit. This enables the main gear unit to be operated at a lower output speed in the same direction of
rotation. The auxiliary drive is connected with the main gear unit by an overrunning clutch. For the basic
drive­train configuration refer to figure 10.
