• Pozidriv and Torx (2.5 … 6 mm, 0.98 … 0.2 in) screwdrivers for the tightening of the frame screws (Screws needed for fastening the cabling boxes and other accessories delivered by ABB are included in the delivery. They are inside the cabinet. The delivery does not contain screws or tools to install the cabinet to the floor.)
Mechanical installation 45 Moving the converter package Moving the converter package by fork-lift WARNING! Only use a heavy duty forklift that can carry the weight of the converter. • Make sure that the reach of the fork lift is long enough. The package is wide and the center of gravity is far from the edges.
46 Mechanical installation Lifting the converter package Max 60 Moving the converter on rollers Do not move the converter on rollers. Unpacking Unpack the wind turbine converter when you have moved the converter to its final installation location, or near it. 1.
The ordering code for ABB lift adapter bars is 3AUA0000154605. 1. Attach the ABB lift adapter to the lifting bars on the roof. 2. Attach the lifting sling to the ABB lift adapter lifting point. 3. Lift steadily.
48 Mechanical installation Lifting the converter Obey these instructions when there are no ABB lift adapter bars in use: 1. Attach the lifting slings to holes of the lifting bars (a). Use long enough slings. See the minimum lifting angle in the figure below.
Mechanical installation 49 Placing the converter The cabinet can be placed into its final position with an iron bar and a wooden piece at the bottom edge of the cabinet. Place the wooden piece carefully to avoid damage to the cabinet frame.
50 Mechanical installation Fastening the cabinet to the floor Bolt the converter to the floor through the holes in each flat bar at the base of the cabinet using M12 screws. We do not recommend welding (see section Electric welding on page 51).
Mechanical installation 51 Lifting the door 1. Open the handles. 2. Detach the upper part of the door. 3. Lift the door upwards. Miscellaneous Cable duct in the floor below the cabinet You can construct cable ducts below the cabinet. The duct width must not exceed 450 mm (18 in).
Note: The installation must always be designed and made according to applicable local laws and regulations. ABB does not assume any liability whatsoever for any installation which breaches the local laws and/or other regulations. Furthermore, if the recommendations given by ABB are not followed, the converter may experience problems that the warranty does not cover.

Planning the electrical installation 59 Single core vs multicore cables in grid cabling Use symmetrical grid cabling. Asymmetry leads to unequal current distribution between the conductors which may cause disturbances and fault trips. To avoid asymmetry, use symmetrical multicore (three-phase) cables where possible. Single core cabling is also allowed if the cables are grouped symmetrically.
60 Planning the electrical installation Selecting the DC resistors For further information, contact your local ABB representative. Selecting the control cables General rules All control cables must be shielded. As a general rule, the control signal cable shield should be grounded directly in the wind turbine converter.
Planning the electrical installation 61 Routing the cables Route the generator cable away from other cable routes. It is recommended that the generator cable, grid cable and control cables are installed on separate trays. Avoid long parallel runs of generator cables with other cables in order to decrease electromagnetic interference caused by the rapid changes in the converter output voltage.
62 Planning the electrical installation Protecting the converter installation Protecting the grid cable in short-circuit situations Equip the cable with fuses. Size the fuses according to local safety regulations, appropriate voltage and the rated current of the converter. Protecting the generator and generator cable in short-circuit ...
