3 Circuits
3.1 Operation with electronic control gear (ECG)
OSRAM DULUX ® S/E, D/E, and T/E PLUS with four-pin bases, T/E HE, XT and CONSTANT lamps
and OSRAM DULUX ® L 40, 55 W and 80 W lamps (including XT and CONSTANT types) have been
designed to operate with electronic control gear only. OSRAM DULUX ® L and F 18, 24, 36 W and
the CFL SQUARE ® four-pin can be operated with either electronic or magnetic control gear.
To ensure safe operation of both, the lamp and the ECG, the wiring between the outputs of the ECG
and the terminals on the lamp holder(s) must be correct. This applies not only to two-lamp arrange-
ments but also to single-lamp configurations. Certain cables from the ECG to the lamp or lamps
(„hot ends“) should be kept as short as possible to avoid issues with radio interference. This means
one should choose an asymmetrical mounting location in the light fitting to increase the length of
the low potential cables if you can thereby shorten the lamp cables carrying high potential.
The correct circuit layout is generally printed on the ECG casing. Check with the ECG manufacturer
to establish which terminals are the „hot ends“. This information may be shown on the casing (e.g.
„keep wires x and y short“).
With dimmable ECGs the length of the control cable(s) and the way in which they are laid also play a
role. For further information on this topic please consult the OSRAM QUICKTRONIC
® technical
guides or visit www.osram.com/quicktronic .
Another important factor with ECGs is the t c measuring point on the casing. The temperature indi-
cated here must not be exceeded during operation otherwise the unit will fail prematurely.
A prominent characteristic of electronic control gear, and one that applies to most units (see infor-
mation on the casing) is whether or not it is suitable for dc operation (for approximately the same
rms values for AC and DC). In many cases, a DC-compatible ECG can also be used in emergency
lighting systems. The relevant regulations governing emergency lighting must be observed.
QUICKTRONIC
® control gear from OSRAM is suitable for emergency lighting in accordance with
DIN VDE 0108-100 / EN50172.
Information from the manufacturers regarding circuits (circuit diagrams) can generally be found on
the casing cover.
