Standard cabinet layout

Several inverter modules of frame sizes R1i...R4i may be installed in one cubicle. The
standard cubicle width is 400, 600, 800 or 1000 mm depending on the size and number of
inverter modules installed.
Each module has dedicated DC fuse disconnectors. The motor (output) connections are
located at the lower part of the cubicle; depending on the power of the inverter module,
these are either detachable or non-detachable terminal blocks.
The cubicle is equipped with cable entries for the motor cables in the floor.
The picture below presents an example of a 600 mm wide cubicle with three R1i, one R3i
and two R4i modules.
