B44020 Screw terminals Accessories Mounting instructions Insulated mounting with washer and cap nut: Mounting stud has the same potential as the negative terminal. Attention must be paid on any relevant regulations (e.g. VDE, BSA or UL). Please read Cautions and warnings and Important notes at the end of this document.
B44030 Screw terminals Accessories Ring clip mounting Ring clips are primarily used for upright mounting of screw terminal and photoflash capacitors. The ring clips are corrosion protected and are RoHS-compatible. It is recommended to insert an additional insulating strip between capacitor and ring clip to avoid any risk of damage due to edges from the clip. The strip is included in delivery. For ordering code, see the following table. Attention must be paid to any relevant regulations (e.g.

B44030 Screw terminals Accessories Clamp mounting Screw terminal capacitors without threaded stud and with a diameter ≥ 64.3 mm can also be mounted with ring clamps. Clamp mounting offers the following advantages: Optimum heat transfer between capacitor base and board due to pressure contact High vibration resistance Electrically insulated material Dimensional drawing 1 ) Length of screw depends on application.

B44020, B44030 Screw terminals Accessories Cautions and warnings Personal safety The electrolytes used by EPCOS have been optimized both with a view to the intended application and with regard to health and environmental compatibility. They do not contain any solvents that are detrimental to health, e.g. dimethyl formamide (DMF) or dimethyl acetamide (DMAC). Furthermore, some of the high-voltage electrolytes used by EPCOS are self-extinguishing.
B44020, B44030 Screw terminals Accessories Product safety The table below summarize the safety instructions that must be observed without fail. A detailed description can be found in the relevant sections of chapter "General technical information".
B44020, B44030 Screw terminals Accessories Topic Safety information Active flammability Maintenance Avoid overload of the capacitors. Storage Make periodic inspections of the capacitors. Before the inspection, make sure that the power supply is turned off and carefully discharge the electricity of the capacitors. Do not apply excessive mechanical stress to the capacitor terminals when mounting. Do not store capacitors at high temperatures or high humidity.
