Overload protection
Automatic shutdown of the LED Driver if the maximum output current is
exceeded. Automatic restart if the output current is below the limit.
No-load operation
The LED Driver is not damaged in the no-load operation. The max. output
voltage (see page1) can be obtained during no-load operation.
Over temperature protection
Automatic shutdown of the LED Driver if the temperature limit is exceeded.
Automatic restart if the temperature falls below the limit.
Short-circuit behaviour
In case of a short circuit on the secondary side (LED) the LED Driver switches
into hiccup mode. After removal of the short-circuit fault the LED Driver will
recover automatically.

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.
Wiring type and cross section
The wiring can be in stranded wires with ferrules or solid. For perfect
function of the screw terminals the strip length should be 9–10 mm for
the terminal.
0,5 – 2,5 mm²
Min. Ø = 1 mm
Max. Ø = 9 mm

Release of the wiring:
The terminals have a simple push-in termination. Conductor removal via
screwdriver (2.5 mm x 0.4 mm).
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.

Constant voltage
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.
Additional information
According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A,
each luminaire should be submitted to an isolation test with 500 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.
Guarantee conditions at www.tridonic.com → Services
Additional technical information at www.tridonic.com → Technical Data
Life-time declarations are informative and represent no warranty claim.
No warranty if device was opened.
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.
