ABB ACS2000 DFE - Grounding the Drive

CHAPTER 2 – POWER ELECTRONICS AND CABINET FEATURES 35
When the voltage is below 50 V (DC), press the
pushbutton
Grounding Switch Unlocked (1)
located on the control compartment door (the
pushbutton lights up) and - at the same time - turn
the grounding switch to the grounded (2) position.
When the grounding switch is in position
grounded, the door safety switch of the DFE-INU
compartment is released and the door can be
opened.
2.3.3 INU - Inverter unit
The INU converts the DC voltage to the required AC
motor voltage and frequency. The unit is com-
posed of three identical phase modules, one phase
module per phase U, V and W. The size of the phase
modules depends on the power rating of the drive.
The arrangement of the phase modules in the cabi-
net is the same for all drives.
For information on the dimensions and the weight,
see 10.6.13 Replacing a phase module.
