4.6.3 Unbox and install the IPU
1. Locate the IPU box that is specially marked and contains
the set of lifting eyes and straps.
2. Remove the top and side cardboard panels.
3. Open the lifting kit and attach the M12 load-rated lifting
eyes (1.2 Tonne), lifting slings, and protective pads to the
four lifting points located in each corner on top of the
cabinet.
4. Use a torque wrench to tighten the lifting eyes.
Note:
Use recommended torque settings when fastening
lifting eyes; the settings are written on the parts.

5. Carefully crane the IPU into place, bolt the IPU down,
then detach the crane.
Important: Ensure that the IPU is properly secured by the
bolts before you detach the crane.
Note:
If lifting the IPU from a horizontal position to stand
it upright, it must still be lifted with all four lifting points
attached to the slings going to a central lift point. Only
two slings will be under tension, the other two will act as
safety.
WARNING!
The rain hood and spacers are not appropriately rated for
lifting the unit. Failure to remove them may cause damage to
the IPU and/or serious accident.
WARNING!
NEVER
lift the IPU in a horizontal position if the primary
transformer has been installed. The cabinet is not rated for
this.
SAFETY WARNING!
To ensure that laws and regulations are adhered to, prior to
installation of the piping and wiring, a professional review of
local requirements must be performed. As a result, deviation
from the cable lug sizes and corresponding cable sizes
referenced in this section may be necessary.
