Notice: For fluorescent lamps with capacitors, you must consider the technical data of
fluorescent lamp ballasts. If the current exceeds the maximum allowed surge current,
appropriate contactor relays must switch the flourescent lamps.
The data was determined with the following devices:
● Siemens fluorescent tubes 58 W VVG 5LZ 583 3-1 uncompensated.
● Siemens fluorescent tubes 58 W VVG 5LZ 583 3-1 parallel compensated with 7 μF.
● Siemens fluorescent tubes 58 W VVG 5LZ 501 1-1N with ballast.
