• Disconnect the batteries by removing one of the KBATT plugs (1/Fig.4/p.15) and
(1/Fig.5/p.15) .
• Measure the residual voltage at test points CAPPOS and CAPNEG on board D7
(Fig.3/p.14) . The voltage measured must be less than 2 VDC
WARNING
Risk of electrical shock!
Non-compliance can lead to injuries or death.
¹ If the voltage measured between CAPPOS and CAPNEG
is 0 V, the measurement device could be defective or the
wires between the CAPPOS and CAPNEG test points on
the capacitor bank could be damaged.
¹ The capacitors could still be charged.
¹ In this case, proceed as follows:
- Make sure that the correct measurement range is set on the measurement device.
- Connect the measurement device to CAPPOS and CAPNEG.
- Switch S10 off. Connect the mains cable and switch the system ON.
- Check whether the voltage increases.
- Switch the system OFF, disconnect the cable and switch S10 on.
- Check whether the voltage decreases.
WARNING
If U11 or U301 is blown, the capacitor in M11 will not be discharged
with S10.
The capacitors could still be charged.
¹ Verify that U11 or U301 has not blown. The capacitor in
M11 must then be discharged as stated below.
- 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, see (Fig.6/p.16) .
