Standards EN EN 61-3-2 EN 61-3-3 EN 61347-1 EN 61347-2-13 EN 647 EN 62384 Overload protection If the output voltage range is exceeded the LED Driver will protect itself and LED may flicker. After elimination of the overload the nominal operation is restored automatically. Short-circuit behaviour In case of a short circuit on the secondary side (LED) the LED Driver switches into hic-cup mode. After the removal of the short-circuit fault the nominal operation is restored automatically. No-load operation The LED Driver works in burst working mode to provide a constant output voltage regulation which allows the application to be able to work safely when LED string open due a failure.

Installation instructions The LED module and all contact points within the wiring must be sufficiently insulated against 3. kv surge voltage. Air and creepage distance must be maintained. Replace LED module 1. Mains off 2. Remove LED module 3. Wait for 1 seconds 4. Connect LED module again Hot plug-in or secondary switching of LEDs is not permitted and may cause a very high current to the LEDs. Wiring type and cross section The wiring can be in stranded wires with ferrules or solid. For perfect function of the cage clamp terminals the strip length should be 9 1 mm for the input terminal. The max. torque at the clamping screw (M3) is.2 Nm. Use one wire for each terminal connector only. Use each strain relief channel for one cable only. min. = 3.3 mm max. = 6. mm The following cable types are approved and recommended by Tridonic: RVVB 2x. mm² H3VVH2-F2G.7 RVVB 2x1. mm² RVV 2x1. mm² Wiring guidelines All connections must be kept as short as possible to ensure good EMI behaviour. Mains leads should be kept apart from LED Driver and other leads (ideally 1 cm distance) Max. lenght of output wires is 2 m. Secondary switching is not permitted. Incorrect wiring can demage LED modules. To avoid the damage of the Driver, the wiring must be protected against short circuits to earth (sharp edged metal parts, metal cable clips, louver, etc.).

SR SNC ~ ~ Isolation 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 698-1 Annex Q (informative only!) or ENEC 33-Annex A, each luminaire should be submitted to an isolation test with V DC for 1 second. This test voltage should be connected between the interconnected phase and neutral terminals and the earth terminal. The isolation resistance must be at least 2 MΩ. As an alternative, IEC 698-1 Annex Q describes a test of the electrical strength with V AC (or 1.414 x V DC). To avoid damage to the electronic devices this test must not be conducted.
