4.6 Isolated power unit installation
4.6.1 Access and clearance
To maintain accessibility and serviceability of the unit via the
cabinet doors, the front and rear of the IPU should be spaced
at least 1m from any walls. This also aids in ventilation of the
units.
If the IPU cabinets are required to be serviceable to the point
where the primary IPU transformer may be removed in the
future, make allowance for enough spacing between the rear
of the unit to fit the length of a forklift and associated lifting
tines, and additional maneuvering space.
4.6.2 Foundation - precast preparation
Foundation design and preparation is the responsibility of the
customer. Device footprints are provided by Siemens for hole
drilling and conduit/cable location guidance.
For a full-scale drawing of Figure 5 and Figure 6, see the
following documents respectively:

Note:
A mounting stencil may be supplied by Siemens at
customer request. All lengths in the below figures are
specified in millimeters.
