6 Removing the Left Enclosure Lid
4. Ensure that the voltage on the capacitors between T
(red) and S (green) and T (red) and R (yellow) is
less than 60 V within the DC measuring range.
5. Ensure that the voltage on the DC link between
BUS+ and BUS- is less than 60 V in the DC
measuring range.
6. Actively discharge capacitors: For this purpose use,
for example, a 2-pole voltage detector that does not
have its own voltage source. Measure with the
voltage detector between T (red) and S (green) and
T (red) and R (yellow) until a value of less than 5 V
in the measuring range is displayed.
