Hexagonal recess
All self-ventilated motors, sizes 71 to 160 with mounted brake or
backstop have a hexagonal recess in the motor shaft extension
at the non-drive end (NDE). As a consequence, frequently it is
not necessary to mount a handwheel.
A hexagonal recess is not possible for rotary pulse encoder or
second shaft extension.

Canopy
Geared motors with a vertical mounting position (motor at the
top) can also be fitted with a canopy. The canopy prevents small
items from falling into the geared motor; in the case of outdoors
installation, its primary function is to serve as a rain canopy.
If the motor is to be used or stored in the open air, we recom-
mend that it is kept under additional cover to protect it from pro-
longed exposure to direct sunlight, rain, snow, ice, or dust.
