2.3 Power
cabling
2.3.1 Shielded motor cable
In crane application inverter fulfils EN61800-3/A11 (IEC 1800-3) second environment radiated emission
requirements without shielded motor cable.
In the second environment, shielded motor cable is recommended to use in fixed installations, especially in
buildings. However motor cables in crane and festoon power supplies are normally not shielded due to the
practical reasons.
Shielded motor cable is essential to use if installation is requested to fulfil the first environment emission
requirements.
2.3.2 Double
collectors
If the power is supplied to the crane via conductor rails, double collectors are needed. This ensures a reliable
contact with the rail in all circumstances. Short interruptions and sparks between the conductor rail and the
collector may cause nuisance tripping, other undesired operations and in worst case even permanent damage
to components.
2.3.3 Cable
selection
Cabling for inverter can be done using normal crane cables. All the cables must be dimensioned according to
local regulations. Ambient temperature, cabling method (size of bunches etc.) and allowable current for the
cable in use must be taken into consideration. If there are no other regulations, following values can be used
(three phase 400V supply).
The table below is based on ED
≤
60% and ambient tempe40°C (104°F). A higher ambient
temperature may require increased cable sizes. The input current does not exceed the continuous current
(Icont) of inverter, so it is selected to be the dimensioning current. If the actual load current is below inverter
continuous current, then the fuses and the supply cable may be dimensioned according to the load current.
