3.1.1 Planning the Installation Site

NOTICE
Due to the size and clearance requirements of the active
filter, it is important to pre-plan installation. Failure to
do so may result in additional work during and after
installation.
Select the best possible operation site by considering
the following:
•
Ambient temperature conditions.
•
Altitude at installation point.
•
Installation and compensation method.
•
Cooling.
•
Position of the active filter.
•
CT installation point and possibility to reuse
existing CTs.
•
Cable routing and EMI conditions.
•
Ensure the power source supplies the correct
voltage and frequency.
•
If the unit is without built-in fuses, ensure that
the external fuses are rated correctly.

3.1.2 Receiving the Active Filter

When receiving the unit, ensure that the packaging is
intact, and note any damage that may have occurred
during transport. In case of damage, immediately contact
the shipping company to claim the damage.
NOTICE
Damaged packaging can indicate rough transportation
which may have caused interior failures in the unit.
Claim damages even if the exterior of the unit seems
intact.

3.1.3 Transportation and Unpacking

Place the active filter as close as possible to its final instal-
lation site before unpacking it. Keep the filter on the pallet
and boxed as long as possible to avoid damage.

3.1.4 Lifting

Always lift the unit in the dedicated lifting eyes. Use a bar
to avoid bending the lifting holes.
Illustration 3.1 Recommended Lifting Method for AAF 006,
Enclosure Sizes D14 and E1
NOTICE
The lifting bar must be able to handle the weight of the
unit. See chapter 3.1.5 Mechanical Dimensions for
weights. Maximum diameter for the bar is 25 mm (1
inch). The angle from the top of the unit to the lifting
cable should be > 60°.
NOTICE
The plinth is required to allow airflow to the unit to
provide proper cooling.
