7 Installation

7.1 Installation directives

If the Drive Unit is to work properly it must be installed in accordance with
these instructions. The conditions the unit will operate in must be taken into
consideration.
Improper installation, not following the instructions in this manual and in the
attached technical documentation, may affect the function and/or the service life
of the Drive Unit. It is important that the safety precautions in this manual always
are followed.
Position the Drive Unit:
• on a firm level foundation to avoid vibrations.
• to ease maintenance and service (see 7.3: Positioning the Drive Unit).
• protected from weather, airborne sprays, heavy contaminations and radiated heat.
• to ensure free ventilation for cooling purposes for the electric motor and the air-
oil cooler. See Fig. 17 and Fig. 36.
• to minimize pipe runs.
Clamp each pipe in the pipe run separately and attach it to a firm foundation to
avoid vibration. The hydraulic connections from the Drive Unit must always be
fitted to the piping with hoses. If air-oil cooler is mounted at a location other than
on the Drive Unit, it must be considered that the cooler will start without notice
and has sharp edges.
