1  INSTALLATION 
1.9  Cubicles 
Inverter is delivered with external braking resistor. Braking resistor types D2FR are installed in the same cubicle as the 
inverter itself. Braking resistor D2HR04F90R0S4 for 002 –005 is in own cubicle. 
Power class  Standard cubicle  Cubicle size (mm)  Braking resistor (mm) 
002 - 005  EEO25.604  400 x 600  400 x 400 
007 – 015  CC600E  600 x 1000  Included 
018 – 030  KA220D2  1000 x 1000  Included 
037, 045  1½  x KA220D2  1½  x 1000 x 1000  Included

1.10  Braking resistor 
Inverter is delivered with external braking resistor. Braking resistor types D2FR are equipped with cooling fans and 
thermistors. Circuit diagrams are in appendix.

In case of 2 resistor units, power supply to transformers has to be taken from the same phases. 
1.11  Power cabling 
1.11.1 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. 
1.11.2 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. 
1.11.3 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 temperature +40°C (104°F). A highe r 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.
