Cautions
Discharge and short circuit capacitor before handling!
Mechanical damage
In case of dents of more than 0.5 mm or any other mechanical damage, capacitors must not be used at all.
Vibration resistance
The resistance to vibration of capacitors corresponds to IEC 68, part 2–6. Max. test conditions:
Test duration 2 h corresponding to max. 0.7 g
Frequency range 10 ... 55 Hz corresponding to max. 0.7 g
Displacement amplitude 0.75 mm corresponding to max. 0.7 g
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.
Connection
Make sure connection cables are of flexible type or flexible copper bands are used. This is mandatory to
allow the overpressure disconnector work and avoid mechanical stress on the terminals and feed throughs.
The connection cables to the capacitor should be designed for a current of at least 1.5 times the rated
current so that no heat is conducted into the capacitor. If reactors are used in an application, the distance
between reactor and capacitor must be great enough so that no heat of the reactors, which are operating at
a much higher temperature level, is conducted via connection cable to the capacitors.
Avoid bending cable lugs, cables or other mechanical force on the terminals. Otherwise leakages may set
the safety device out of operation. Ensure firm fixing of terminals, fixing torque to be applied as per
individual specification. Maximum specified terminal current (please refer to technical data of specific
series) must not be exceeded at any case.
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 nut should be
removed.
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.
U Please read information about PFC capacitors and cautions as well as installation and maintenance
instructions (Power Factor Correction Product Profile, actual version) to ensure optimum performance
and prevent products from failing, and in worst case, bursting and fire, etc.
Information given in the PFC-product profile and values given in the data sheet reflect typical
specifications. You are kindly requested to approve our product specifications or request our approval
for your specification before ordering.
