Cut the cables to suitable length.
Strip the cables and conductors.
Twist the cable screens into bundles and connect to cabinet PE (ground) busbar.
Connect any separate ground conductors/cables to cabinet PE (ground) busbar.
Connect the phase conductors to the output (U2, V2, W2) and input (L1, L2, L3) terminals. See section
in chapter Technical data.
Insert each module into the cabinet as follows:
(1) Move the module close to the ramp. With converter modules, retract the support legs of the module.
(2) Push the module back into the cabinet.
(3) Refasten the module fixing screws at the top. Reconnect the busbars and the cables (socket terminal block, fibre
optic cables).
(4) Remove the pull-out ramp.
(5) With converter modules, flip the module fastening bracket into the down position and tighten the screws. With LCL
filter module, fix the four fastening screws at the bottom of the filter module and reconnect the fan.
(6) Replace the shroud covering the upper part of the cabinet.
(7) Close the doors.
(8) At the generator, connect the cables according to instructions from the generator manufacturer. Pay special
attention to the phase order.

Control connections

The cabinet installed unit is controlled using the local control devices mounted in the
control frame. See sections
chapter
However, it is possible to:
• halt the unit by an external emergency stop button (if the unit is equipped with a
local emergency stop button, external buttons can be connected in series)
• read fault indications through a relay output
• communicate with the unit through a serial communication interface.
See the circuit diagrams delivered with the converter for the default control
connections and the connection terminals.

Connection procedure

• Lead the cables into the cabinet below the control unit. Wherever possible, use
the existing cable trunking in the cabinet. Use sleeving wherever the cables are
laid against sharp edges. Leave some slack in the cable (at the hinge) to allow
the control unit to extend fully. Tie the cables to the braces to provide strain relief.
• Cut the cables to suitable length. Strip the cables and conductors.
• Twist the cable shields into bundles and connect them to the ground terminal
nearest to the terminal block. Keep the unshielded portion of the cables as short
as possible.
• Connect the conductors to appropriate terminals (see the circuit diagrams
delivered with the unit).
