Cautions and warnings
Safety
■ 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 leakage.
■ Electrical or mechanical misapplication of capacitors may be hazardous. Personal injury or prop-
erty damage may result from bursting of the capacitor or from expulsion of oil or melted material
due to mechanical disruption of the capacitor.

■
Ensure good, effective grounding for capacitor enclosures.
Observe appropriate safety precautions during operation (self-recharging phenomena and the
high energy contained in capacitors).
Handle capacitors carefully, because they may still be charged even after disconnection.
The terminals of capacitors, connected bus bars and cables as well as other devices may also
be energized.
Follow good engineering practice.
Failure to follow cautions may result, worst case, in premature failures, bursting and fire.
Thermal load
After installation of the capacitor it is necessary to verify that maximum hot-spot temperature is not
exceeded at extreme service conditions (see www.epcos.com/thermal_design).
Mechanical protection
The capacitor has to be installed in a way that mechanical damages and dents in the aluminum can
are avoided.
Storage and Operating Conditions
Do not use or store capacitors in corrosive atmosphere especially where chloride gas, sulfide gas,
acid, alkali, salt or the like are present. In dusty environments, regular maintenance and cleaning
especially of the terminals is required to avoid conductive path between phases and/or phases and
ground.
Overpressure disconnector
To ensure full functionality of an overpressure disconnector, the following must be observed:
■ The elastic elements must not be hindered, i.e.
– connecting lines must be flexible leads (cables),
– there must be sufficient space (minimum 12 mm) above the connections for expansion of the
overpressure disconnector,
– folding crimps must not be retained by clamps.
■ Stress parameters of the capacitor must be within the IEC61071 specification.
Service life expectancy
Electrical components do not have an unlimited service life expectancy; this applies to self-healing
capacitors too. The maximum service life expectancy may vary depending on the application the
capacitor is used in.
