3 Transport, Installation and Connection
68 BA8230
3.1 Safety instructions During transport and on installation of each unit it is important to remember that the
centre of gravity is not located at the centre of the unit itself. The asymmetrical loads
resulting during transit and installation must therefore be taken into account
accordingly.
Heavy units must always be lifted using suitable equipment and trained personnel.
Units may only be transported in the correct position using the eyebolts provided.
They may not be placed on their side for transportation purposes. A pallet must be
used for transport with a forklift truck.
Uniform distribution of the load is essential when lifting. The force applied to all
eyebolts must be equal.
The support cables may not vary more than 30 degrees from the vertical.
Heavy vibration and severe shock must be avoided during transport and when lifting
and lowering.
After installation the eyebolts should be removed and stored safely in case they are
needed in the future.
Incorrect lifting and transportation of the units can cause severe or even fatal physical
injury and extensive material damage.
Build-in units are designed for wall-mounting. The securing bolts to be used must
always be of the correct size (see section 3.4).
Please note the following when connecting inverters:
•
All work on the unit and its installation must be executed in accordance with the
national and local electrical regulations and conditions. This means that the inverter
must be earthed correctly at the protective earth connections to ensure that no
easily accessible part of the unit is at mains potential or carries any other
dangerous voltage.
Attention!
If inverters are not earthed it is possible for the casing to carry dangerous voltages
which can cause fatal or severe physical injury or extensive material damage.
•
Check that the load connected, i.e. the cables and motors, are not earthed.
•
Check the rated supply voltage and current as well as the motor data
according to the 8230 frequency inverter rating plate.
•
Build-in units must be installed in panelled cubicles or rooms which are only
accessible to trained personnel.
•
The user is responsible for ensuring that inverters and other equipment are
installed and connected in accordance with the accepted rules of technology and
the local regulations in the country concerned. This must take into account the
cable dimensions, fusing, earthing, isolation, separation, insulation monitoring and
overcurrent protection in particular.
The safety instructions given inside the cover and in section 5.1 must be observed.
