When receiving the frequency converter, make sure that
the packaging is intact. Also be aware of any damage that
might have occurred to the unit during transport. In case
damage has occurred, immediately contact the shipping
company to claim the damage.

Before unpacking the frequency converter, place the unit
as close as possible to the final installation site.
Remove the box and handle the frequency converter on
the pallet, as long as possible.
