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 500VDC for 1 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 2MΩ.

As an alternative, IEC 60598-1 Annex Q describes a test of the electrical strength with 1,500VAC (or 1,414 x 1,500VDC). To avoid damage to the electronic devices this test must not be conducted.

Wiring diagrams

Serial wiring with one or two LED modules

Parallel wiring with multiple LED modules (3 – 12)

Take care that the LED is connected with the right polarity.

LED that are connected to the EM powerLED devices should have a reverse polartity protection device such as a schottky diodes fitted, otherwise irreversible damage could occur if the LED is connected in reverse polarity. Any protection device must be capable of handling in excess of 700 mA.
Note: Please ensure that at the terminal of the EM powerLED module the battery negative is not connected to the negative of the LED load.

Manually tested emergency lighting with combined LED modules for general and emergency lighting

Due to the fact that independent circuits are used for general and emergency lighting it is important that the normal supply of the mains LED driver is switched off together with the permanent emergency supply prior to checking the operation of the emergency LEDs. If this is not done then it may not be possible to see that the emergency
LEDs are operating. Use a circuit similar to that shown next.

89899860 Wiring instructions

• The EM powerLED terminals, battery, indicator LED and test switch terminals are classified as SELV. Keep the wiring of the DALI and the input terminals separated from the wiring of the SELV terminals or consider special wiring (double insulation, 6 mm creepage and clearance) when these connections should be kept SELV.
• The output to the LED is DC but has high frequency content at 125 kHz, which should be considered for good EMC compliance.
• EM powerLED leads should be separated from the mains and DALI connections and wiring for good EMC performance.
• Maximum lead length on the EM powerLED terminals is 3 m. For a good EMC performance keep the LED wiring as short as possible.
• The secondary wires (LED module) should be routed in parallel to ensure good EMC performance.
• 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 EM powerLED leads to prevent noise coupling.
• Battery leads are specified with 0.5 mm2 cross section and a length of < 1.3 m.
• DALI terminals are mains proof.
• Switched live and unswitched live supplies must be off the same phase.
• To avoid the damage of the control gear, the wiring must be protected against short circuits to earth (sharp edged metal parts, metal cable clips, louver, etc.).
