Notes:

•

• Max. lamp cable length of the "hot end" (higher potential to

ground): T5, T8: 1 m/T4: 0.5 m

•

• Excessively long lamp cables cause the following problems:

- Poor radio interference suppression

- Uncertain lamp detection (not in T8)

- Poor synchronization of 2-lamp OSRAM DALI/DIM ECGs

• Lay the lamp cables close together and close to the lamp

• Lamp cables must not be laid in metal pipes and must not be

shielded cables

• Guide the cables of the different lamp ends separately

• In the case of multi-lamp OSRAM DALI/DIM ECGs, the cables to

the respective lamp ends must be of the same length to prevent

differences in the brightness

• When dimming florescent lamps the maximum lamp voltage is

reached at the lowest dimmer setting (3 %-10 %) due to the nega-

tive current-voltage characteristic

lamps

* "Hot ends" are the lamp cables that have the highest potential to the

switching ground or protective ground. The other "cold ends" of the

lamp cables have a lower potential to ground.

Note:

• Maximum capacitance of a filament cable pair to ground:

T5: 75 pF

T8/DL: 150 pF

• Maximum capacitance between "hot" and "cold":

T5: 15 pF

T8: 30 pF
