Bridging busbars
Inverter unit cubicle(s)
The recommended cable types are given in the technical data.
WARNING!
The bridging can carry the nominal output of one inverter module. In case of
three parallel modules, make sure that the load capacity of the bridging is not
exceeded. For example, if the cabling connects to the output busbars at one
module only, use the module in the middle.
Note: The +H366 option only interconnects the outputs of inverter modules within
the same cubicle, not modules installed in different cubicles. Therefore, when the drive
has multiple inverter cubicles (ie. two cubicles of two modules each), make sure that
the motor cabling is identical for both cubicles.

Procedure
To get more space for cabling work, you can remove the inverter modules or the fan
carriages of each module. Especially in the case of multiple inverter modules in the
same cubicle, you can consider only removing the fan carriages. This is faster than
removing the entire module, but gives less free space for the work than removing the
module.
Removing an inverter module
Refer to section Removing an inverter module (page 202).
Removing the fan carriage of an inverter module
Refer to the drawings below.
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or
death, or damage to the equipment can occur.
1. Do the steps in section Electrical safety precautions (page 21) before you start
the work.
2. Open the inverter module cubicle door.
