1.1 Glow-wire test
according to EN 61347-1 with increased temperature of 850 °C passed.
1.2 Insulation and electric strength testing of luminaires
Electronic LED-Drivers can be damaged by high voltage. This has to be consid-
ered during the routine testing of the luminaires in production.
According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A,
each luminaire should be submitted to an insulation test with 500 V
DC
for 1 sec-
ond. This test voltage should be connected between the interconnected phase
and neutral terminals and the earth terminal. The insulation resistance must be
at least 2 MΩ.
As an alternative, IEC 60598-1 Annex Q describes a test of the electrical
strength with 1,500 V
AC
(or 1,414 x 1,500 V
DC
). To avoid damage to the electronic
devices this test
must not be conducted
.
2. Thermal details and life-time
2.1 Life-time
Average life-time 50,000 hours under rated conditions with a failure rate of
less than 10 %. Average failure rate of 0.2 % per 1000 operating hours.
3. Installation / Wiring
3.1 Wiring diagram
One or more LED modules with a total forward voltage of 10 to 54 V can be
connected to the EM converterLED. These LED module(s), marked with “Emer-
gency” are operated in emergency mode from the associated battery. In normal
mains mode all LED modules are operated by the mains LED Driver.
Meaning of marking
Double or reinforced insulation for built-in electronic LED Drivers. The control
gear relies upon the luminaire enclosure for protection against accidental contact
with live parts.

The emergency lighting LED Driver is designed for a life-time stated above
under reference conditions and with a failure probability of less than 10 %.
The relation of tc to ta temperature depends also on the luminaire design.
If the measured tc temperature is approx. 5 K below tc max., ta tempera-
ture should be checked and eventually critical components (e.g. ELCAP)
measured. Detailed information on request.
