- Measure the voltage on the capacitors in M11 and check that the voltage level is <2 V
DC. If not, discharge the capacitors with R103 (Fig. 5).
Fig. 5
If U11 or U301 is blown, the capacitor in M11 will not be dis-
charged with S10.
The capacitors could still be charged.
Verify that U11 or U301 has not blown. The capacitor in M11 must
then be discharged as stated below.
If the charging/discharging does not function, the power conver-
sion unit M10 and M11 must be considered “charged”.
This means a risk of high voltage.
Use caution when performing measurements at the capacitors in
M10 and M11.
Use only the specified measurement devices (350 V DC).
