9.2.1. Tests
9.2.2. Insulation and dielectric strength testing of luminaires
LED Driver for lamps are sensitive to high-voltage transients. This must be taken into consideration when subjecting luminaires to
routine testing during manufacture.
According to IEC 60598-1 Annex Q (for information only!) and ENEC 303-Annex A, each luminaire should be subjected to an insulation
test for 1 second at 500 V DC. The test voltage is applied between the linked phase/neutral conductor terminal and the protective
earth terminal. The insulation resistance must be at least 2 megaohm.
9.2.3. Type testing
Type testing of the luminaire is performed according to IEC 60598-1 Section 10.
The wiring for protection class 1 luminaires is tested at a voltage of 2xU + 1,000 V. In order not to overload the control gear all the
inputs and outputs of the control gear are connected to one another.
U is used for measuring the voltage for luminaires with control gear with U > 250 V:

For U 480 V the voltage for the type test is 2000 V.

NOTICE
The performance of the prescribed tests and compliance with relevant standards are the responsibility of the luminaire
manufacturer.
The following descriptions merely indicate the most important tests and are no substitute for a full research of the relevant
standards.
½
CAUTION!
As an alternative to measuring the insulation resistance, IEC 60598-1 Annex Q describes a dielectric strength test at 1500 V AC (or
1.414 x 1,500 V DC). To avoid damaging electronic control gear, it is strongly disadvised to perform this dielectric strength test.

NOTICE
The wiring procedure is device specific. Further information about wiring, wire cross sections and the length of stripped off
insulation can be found in the data sheet.
The cables should be run separately from the mains connections and mains cables to ensure good EMC conditions.
_
Maximum lead length for the test switch and indicator LED connection is 1 m.
_
The test switch and indicator LED wiring should be separated from the LED leads to prevent noise coupling.
_
The battery wires are specified with a cross section of 0.5 mm and a max. length of 1.3 m.
