Standard cabinet layout
Several inverter modules of frame size R5i can be installed in one cubicle. The standard
cubicle widths are 300 (check availability with ABB) and 500 mm. The number of modules
that can be fitted into the cubicle also depends on the optional equipment selected.
Each module has dedicated DC fuse disconnectors. The motor (output) connections are
detachable plug connectors located at the lower part of the cubicle.
The cubicle is equipped with cable entries at the floor.
The picture below presents an example of a 500 mm wide cubicle with four R5i modules.
