Storage and transport
NOTICE
Draining the heat sink
Liquid cooled devices may be transported only with the heat sink completely
drained of the coolant. Use compressed air to drain the heat sink radiator.
3.1
Storage
NOTICE
Damage caused by incorrect storage
Wrong or inappropriate storage may result in damage, e.g. due to moisture and
dirt. Avoid major temperature variations and high air humidity.
During storage, protect the device against moisture and dirt.
The frequency inverters must be stored in an appropriate way. During storage, the devices must
remain in their original packaging.
The units may only be stored in dry rooms which are protected against dust and moisture and are
exposed to small temperature deviations only. The requirements of DIN EN 60721-3-1 for storage,
DIN EN 60721-3-2 for transport and labeling on the packaging must be met.
The duration of storage without connection to the permissible nominal voltage may not exceed
one year. After one year of storage, connect the device to mains voltage for 60 minutes.

Special safety instructions on transport of heavy frequency inverters
WARNING
High weight and unusual center of gravity!
Tilting the frequency inverter may result in death or serious injuries. Due to the size and
weight of the frequency inverter, there is the risk of accidents during transport. Center
of gravity is not the middle of the frequency inverter. The underside of the frequency
inverter, due to its design, cannot support the frequency inverter.
Take utmost care during transport in order to prevent damage and deformation.
Transport, attachment and lifting of loads may only be carried out by specially
instructed staff who are familiar with the work.
Only use suitable transport and lifting equipment with sufficient carrying capacity.
The lifting cables/chains used must be able to carry the weight of the frequency
inverter. Check the ropes or chains for damage.
Wear appropriate safety clothing.
When lifting the frequency inverter up ensure that it does not fall over, is displaced,
swings out or falls down.
Before the frequency inverter is lifted up, everybody must have left the work area.
Before transport, make sure the transport path has sufficient carrying capacity.
Do not step under suspended loads.
Do not put the frequency inverter down in upright position without providing a
suitable supporting structure.
