Cautions and warnings

In case of dents of more than 1 mm depth or any other mechanical damage, capacitors must not be used at

all.

Check tightness of the connections/terminals periodically.

The energy stored in capacitors may be lethal. To prevent any chance of shock, discharge and short-circuit

the capacitor before handling.

Failure to follow cautions may result, worst case, in premature failures, bursting and fire.

EPCOS AG is not responsible for any kind of possible damages to persons or things due to improper

installation and application of capacitors for power electronics.

Safety

Electrical or mechanical misapplication of capacitors may be hazardous. Personal injury or property 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.

Thermal load

After installation of the capacitor it is necessary to verify that maximum hot-spot temperature is not exceeded at

extreme service conditions.

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.

The maximum storage temperature is 85 °C.

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.
