28000412 Wiring

28000412 Installation instructions

The switching of LEDs on secondary side is not permitted.
The functioning of the LCU in combination with dimming devices (e.g. PWM) cannot be guaranteed and has to be checked individually before using in combination.
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.).

28000412 Wiring type and cross section

The wiring can be in fine-stranded wires with ferrules. For perfect function of the terminals the strip length should be 9–10 mm for the terminal.

The maximum secondary cable length at the terminals is 2 m.

The LED wiring should be kept as short as possible to ensure good EMC.

Overload protection

If the maximum load is exceeded by a defined internal limit, occurs an automatic shutdown of the LED Driver. Automatic restart if the output current is below the limit

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 500V DC 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 1500V AC (or 1.414 x 1500V DC). To avoid damage to the electronic devices this test must not be conducted.
