1. Connection and fixation
The MKP capacitors are fixed by an M8 or M12 bottom screw. For lighting capacitors in plastic can an alternative fixation with side clip is available.

The following kinds of connection are available as standard.

Solder lug 3 mm
- type R acc. to DIN 41 496 (for connecting wires up to 1.5mm²) tab connector 2.8 mm
- type A acc. to DIN 46 244 part 1 tab connector 6.3 mm
- type A acc. to DIN 46 244 part 1 dual tab connector 6.3mm
- type A acc. to DIN 46 244 part 1

Push wire terminal
- capacitor terminal type with internal discharge resistor, suitable for currents of up to 10A and connecting wires of 0.5 mm²…1.5 mm²

Wires
- 200 mm, 0.5-0.75 mm²

Cable
- Hose line 250 mm, 0.75 mm²

Make sure to use connecting wires or cables of sufficient length and flexibility when connecting capacitors with break-action mechanism in order not to prevent the mechanism from expansion in the event of capacitor failure.

The hermetic sealing of the mkp capacitors is extremely important for a long operating life and for the correct functioning of the beak action mechanism. Please pay special attention not to damage the rubber seal and the soldering at the bottom of the tab connectors.

2. Mounting Position/Distance to Other Components
All capacitors can be mounted without restrictions in any position. A clearance of at least 10mm above the terminals shall be accommodated for capacitors with break-action mechanism.

Capacitors shall not be mounted in the close vicinity of heat, light or heat convection sources (such as conventional ballasts, lamps, heating spirals, etc.); high temperatures as well as steady UV-radiation may cause premature ageing. Capacitors without filling should not be mounted directly on vibration sources (such as motors, ventilators, gear boxes, etc.).

3. Operating voltage
The capacitors have been designed for continuous operation at the rated voltage stated on the label; the related voltage can be exceeded within the limits permitted by applicable standards only:

1.1 x Un
8 h/d

1.15 x Un
30 min/d

1.2 x Un
5 min/d

1.3 x Un
1 min/d

Subject to inductive components within the capacitor circuit, lighting capacitors connected in series with the ballast as well as motor run capacitors are exposed to voltages which permanently exceed the rated mains voltage. This, and the tolerances of all elements in the circuit as well as their drift due to ageing effects, has to be considered when designing the application and determining the proper capacitor value.

4. Operating temperature
The temperature limits stated in the data charts are relating to the permissible temperature at the surface of the capacitor case. They are not identical with the ambient temperature as the capacitors’ self-generated dissipation heat during operation must be taken into consideration as well.

5. Condensation, Humidity
Condensation on the capacitors is not permitted. The permissible humidity class and climatic category of the capacitors are stated in the data charts. The mentioned limit values for humidity must not be exceeded even during storage.

6. Service Life
The following data is based on empirical experience; in accordance with applicable standards, the stated operating life allows for a limited degradation of the capacitance (depending on type, between 3 and 10%) and a failure rate of up to 3%.

Over-temperatures, over-voltages, harmonic distortion and excessive humidity may reduce the service life expectancy or cause increased failure rates.

7. Disposal
Our capacitors do not contain PCB, solvents, or any other toxic or banned materials. The impregnants and filling materials contain vegetable oil or polyurethane mixtures.
The capacitors are not rated as hazardous goods in transit and do not have to be marked under the Regulations for Hazardous Goods. They are rated WGK 0 (water risk
category 0 “no general threat to water”).

We recommend disposing of the capacitors through professional recycling centres for electric/electronic waste.

The capacitors can be disposed of as follows:

• Capacitors: acc. to European Waste Catalogue (EWC) No. 160216 (“Components taken from discarded equipment”)
• Liquid filling materials: acc. to EWC No. 080402 (“Waste adhesives and sealants free of halogenated solvents”)
• Hardened filling materials: acc. to EWC No. 080404 (“Hardened adhesives and sealants”).
