In case of dents of more than 1 mm depth or any other mechanical damage,
capacitors must not be used at all.
This applies also in cases of oil leakages.
To ensure the full functionality of the overpressure disconnector, elastic elements
must not be hindered and a minimum space of 12 mm has to be kept above each
capacitor.
Do not handle the capacitor before it is discharged.
Resonance cases must be avoided by appropriate application design in any case.
Handle capacitors carefully, because they may still be charged even after
disconnection due to faulty discharging devices.
Protect the capacitor properly against over current and short circuit.
Failure to follow cautions may result, worst case, in premature failures, bursting and fire.
Discharging
Capacitors must be discharged to a maximum of 10% of rated voltage before they are
switched in again. This prevents an electric impulse discharge in the application,
influences the capacitor's service life and protects against electric shock. The capacitor
must be discharged to 75 V or less within 3 minutes. There must be not any switch,
fuse or any other disconnecting device in the circuit between the power capacitor and
the discharging device.
