9. Miscellaneous
9.1 Maximum number of switching cycles
All LED Drivers are tested with 50,000 switching cycles.
The actually achieved number of switching cycles is significantly higher.
9.2 Insulation and electric strength testing of luminaires
Electronic devices can be damaged by high voltage. This has to be considered
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 one
second. 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 1500 V
AC
(or 1.414 x 1500 V
DC
). To avoid damage to the electronic
devices this test must not be conducted.
9.3 Conditions of use and storage
Humidity:
5 % up to max. 85 %,
not condensed
(max. 56 days/year at 85 %)
Storage temperature:
-40 °C up to max. +80 °C
The devices have to be acclimatised to the specified temperature range (ta)
before they can be operated.
