— The distance between the lamps should be 32 mm;

distances between the lamps and luminaire parts may

never be less than 6 mm. No part of the luminaire should

touch the lamp glass.

The better these recommendations are implemented, the

quieter and more homogeneous the light at the lowest dim-

mer setting is and the earlier the full temperature range of

the ECG can be used.

— In the “worst case”, twist the cables of the heating

circuits together and ensure that they are laid close to-

gether. In the case of 1-lamp ECGs, these are lines 21–

22 and 26–27, in the case of 2-lamp ECGs, lines 21–22

and 21–23, 24–25 and 26–27. This is especially impor-

tant if neighboring ECGs are being operated at the low-

est dimmer setting (1(3) %).

If problems still occur: Remove all lamps apart from the

one(s) at the “problematic” ECG – this then rules out the er-

rors caused by the other lamps. If the lamp then works

ﬂ awlessly in the entire dimming range, the measures for un-

coupling to the other lamp (lines) are not yet sufﬁ cient.

Correct:

The lamp cables are twisted

and laid close to the re-

spective lamps. None of the

lamp current circuits are

overlapping. The “hot” side

is up, the “cold” side down.

Incorrect:

The lamp cables of all ECGs

are laid together and they

also form overlapping lamp

current circuits.
