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.

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 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 stored 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 case 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.

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.
