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
055 1½ x H15BD02 1½ x 1500 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.
