3.2 Storage 8230 frequency inverter are packed according to the climatic and other conditions
expected in transit and in the country for which they are intended. All notes on the
packaging concerning transport, storage and correct handling must be observed. The
consignment may not be stored outdoors. Stacking is prohibited! Storage rooms must
be dry and well ventilated.
Permitted storage temperature -25 ... +65 °C
8230 frequency inverter units contain high quality aluminium electrolytic capacitors.
Their reliability may be affected if they are stored in the uncharged condition for longer
periods, particularly at high temperatures.
8230 frequency inverter can be stored without charge for at least 2 years, of which
max. 5 months may be at storage temperatures of over 40 °C. The 8230 frequency
inverter should be checked after this storage period has elapsed. The aluminium
electrolytic capacitors should be reformed by suitably trained personnel before
charging at the rated voltage. Please refer to section 7.4 for instructions on forming.
3.3 Transport The units may only be transported with forklift trucks when standing vertically on a
pallet and in their cardboard packaging. When unpacked, transport is also possible
using the eyebolts provided on the inverter. Uniform distribution of the load is
essential. When lifting using the eyebolts the force on all bolts must be equal and
vertical.
Heavy vibration and severe shocks are to be avoided, for example when lowering.
Always check the unit for completeness and any evidence of damage when
unpacking.
If damage in transit is discovered, it must be recorded and reported immediately to the
carriers.
3.4 Installation According to their protection class IP 20 all 8230 frequency inverter units are to be
installed in clean dry rooms ventilated with sufficient clean cooling air according to the
power losses involved. The rated 8230 frequency inverter data may vary in other
protection classes. The volume of cooling air required for the power losses is to be
provided, i.e. adequate ventilation must be ensured. The coolant temperature may not
fall below 0
°
C. If the coolant temperature is above 40
°
C or 50
°
C respectively at
constant load torque and 150 % overload, the current must be reduced by 2 % per
Kelvin up to max. 55
°
C and if the unit is installed above 1000 m to max. 2200 m
above mean sea level an additional current reduction of 1.2 % per 100 m must be
taken into account accordingly.
8230 frequency inverter are designed for vertical wall mounting in switchgear
cubicles, booths and boxes.
The following bolt connections (bolt sizes) are to be used for securing build-in units to
the wall:
