Cautions and warnings
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
ƒ
In case of dents of more than 2 mm depth or any other mechanical damage, capacitors must not
be used at all.
To ensure the full functionality of the overpressure disconnector, elastic elements must not be
hindered and a minimum space of 5 cm has to be kept above each capacitor.
Do not handle the capacitor before it is discharged to max. 10% of rated voltage.
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. PoleCap capacitors have a pre-mounted
ceramic discharge module; alternatively discharge reactors are available from EPCOS. Discharge and
short circuit capacitor before handling!
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.
Safety
ƒ Ensure good, effective grounding for capacitor enclosures.
ƒ Provide means of disconnecting and insulating a faulty component/bank.
ƒ Handle capacitors carefully, because they may still be charged even after disconnection due to
faulty discharging devices.
ƒ The terminals of capacitors, connected bus bars and cables as well as other devices may also be
energized.
ƒ Follow good engineering practice.
Overcurrent and short circuit protection
ƒ Use HRC fuses or MCCBs for short circuit protection. Short circuit protection and connecting
cables should be selected so that 1.5 times the rated capacitor current can be permanently
handled.
ƒ HRC fuses do not protect a capacitor against overload
- they are only for short circuit protection.
ƒ The HRC fuse rating should be 1.6 to 1.8 times rated capacitor current.
ƒ Do not use HRC fuses to switch capacitors (risk of arcing).
ƒ Use thermal magnetic overcurrent relays for overload protection.

Resonance cases
Resonance cases must be avoided by appropriate application design in any case. Maximum total
RMS capacitor current (incl. fundamental harmonic current) specified in technical data must not be
exceeded.
Overtemperature
Exceeding maximum allowed temperature may set the safety device out of operation.
Overpressure disconnector
To ensure full functionality of an overpressure disconnector, the following must be observed:
1. The elastic elements must not be hindered, i.e.
- connecting lines must be flexible leads (cables),
- there must be sufficient space (min. 5 cm) for expansion above the connections (see
“Clearing distance for overpressure disconnector”).
- folding beads must not be retained by clamps.
2. Maximum allowed fault current of 10000 A in accordance with UL 810 standard must be assured by
the application.
3. Stress parameters of the capacitor must be within the IEC60831 specification.
Re-switching vs. phase-opposition
In case of voltage interruption, a sufficient discharge time has to be ensured to avoid phaseopposition and resulting high inrush currents.
Vibration resistance
The resistance to vibration of capacitors corresponds to IEC 68, part 2–6.
Max. test conditions:
Test duration
Frequency range 1
Displacement amplitude
2h
0 ... 55 Hz corresponding
to max. 0.7 g
0.75 mm
These figures apply to the capacitor alone. Because the fixing and the terminals may influence the
vibration properties, it is necessary to check stability when a capacitor is built in and exposed to
vibration. Irrespective of this, you are advised not to locate capacitors where vibration amplitude
reaches the maximum in strongly vibrating equipment.
Mechanical protection
The capacitor has to be installed in a way that mechanical damages and dents in the aluminium can
are avoided.

Clearing distance for overpressure disconnector
Above each capacitor, a minimum space of 5 cm has to be kept. This will allow the visual control to
work and enable a longitudinal extension of the can to secure the over-pressure disconnector work.
Grounding
The threaded bottom stud of the capacitor has to be used for grounding. In case grounding is done
via metal chassis that the capacitor is mounted to, the layer of varnish beneath the washer and the
nut should be removed. The maximum tightening torque is 4 Nm.
Maintenance
ƒ Check tightness of the connections/terminals periodically.
ƒ Take current reading twice a year and compare with nominal current. Use a harmonic analyser or
true effective RMS-meter.
ƒ In case of current above the nominal current check your application for modifications.
ƒ If a significant increase in the amount of non-linear loads has been detected, then a consultant
has to be called in for a harmonic study.
ƒ In case of the presence of harmonics installation of a de-tuned capacitor bank (reactors) must be
considered.
ƒ Check the discharge resistors/reactors and in case of doubt, check their function:
(1) power the capacitor up and down.
(2) After 60 seconds the voltage between the terminals must decline to less than 50 V.
ƒ Check the temperature of capacitors directly after operation for a longer period, but make sure
that the capacitors have been switched off. In case of excessive temperature of individual
capacitors, it is recommended to replace these capacitors as this should be an indication for loss
factor increase which is a sign for reaching end of life.
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.

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical
requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application. As a
rule, EPCOS is either unfamiliar with individual customer applications or less familiar with them
than the customers themselves. For these reasons, it is always ultimately incumbent on the
customer to check and decide whether an EPCOS product with the properties described in the
product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of passive electronic components
or failure before the end of their usual service life cannot be completely ruled out in the
current state of the art, even if they are operated as specified. In customer applications
requiring a very high level of operational safety and especially in customer applications in which
the malfunction or failure of a passive electronic component could endanger human life or health
(e.g. in accident prevention or life-saving systems), it must therefore be ensured by means of
suitable design of the customer application or other action taken by the customer (e.g. installation
of protective circuitry or redundancy) that no injury or damage is sustained by third parties in the
event of malfunction or failure of a passive electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as “hazardous”). Useful information on this will be found in our
Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more
detailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order.
We also reserve the right to discontinue production and delivery of products. Consequently,
we cannot guarantee that all products named in this publication will always be available.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of
the “General Terms of Delivery for Products and Services in the Electrical Industry”
published by the German Electrical and Electronics Industry Association (ZVEI).
7. The trade names EPCOS, CeraDiode, CSSP, PhaseCap, PhaseMod, SIFI, SIKOREL, SilverCap,
