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.
