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