WARNING
Risk of electric shock!
Non-compliance can lead to injury 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 mains cable and switch S10 on.
- Check whether the voltage decreases.
WARNING
If charging/discharging does not function, the capacitor bank
must be assumed to be ”charged”.
This means there is a risk of high voltage.
¹ Use caution when performing measurements at the bus
bar of the capacitor bank. Use only the specified mea-
surement devices (350 V DC). If one of the fuses in the
capacitor series has blown out, this series must be con-
sidered to be fully charged.
