3.3 Installation
Note
Motors up to shaft height 200 may be operated in a vertical or horizontally inclined position.
Vertical types of construction may be inclined through ±45 ° from the vertical axis, and
horizontal types of construction ±45 ° from the horizontal axis. When doing this, forces listed in
the catalog for vertical types of construction or the configured forces should be taken into
consideration.
A canopy may be necessary for explosion-proof motors.
If condensation drain holes are provided, ensure that condensate can be freely discharged or
that sealed condensate holes are also opened.
