Two or more LED modules are operated in emergency mode.
All LED modules are operated in mains mode.
3.3 Loose wiring
8 – 9 mm
wire preparation:
0.5 – 1.5 mm²
3.2 Wiring type and cross section
Solid wire with a cross section of 0.5 – 1.5 mm². Strip 8 – 9 mm of insulation
from the cables to ensure perfect operation of terminals.
Wiring: LED module/LED Driver/supply
Loosen wire through twisting
and pulling or using a Ø 1 mm
release tool
3.4 Wiring guidelines
• The LED terminals, battery, indicator LED and test switch terminals are clas-
sified as SELV (output voltage < 120 V DC). Keep the wiring of the input ter-
minals separated from the wiring of the SELV classified 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, which should be
considered for good EMC compliance.
• LED leads should be separated from the mains connections and wiring for
good EMC performance.
• Maximum lead length on the LED 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 LED
leads to prevent noise coupling.
• Battery leads are specified with 0.5 mm cross section and a length of 1.3 m
• 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.)
To ensure that a luminaire containing LED emergency units complies with
EN 55015 for radio frequency conducted interference in both normal and emer-
gency mode it is essential to follow good practice in the wiring layout.
Within the luminaire the switched and unswitched 50 Hz supply wiring must be
routed as short as possible and be kept as far away as possible from the LED
leads.Through wiring may affect the EMC performance of the luminaire.
The length of LED leads must not be exceeded. Note that the length of the
leads from the EM converterLED to the LED modules is added to the length of
the leads from the LED Driver to the EM converterLED module when conside-
ring the max. permitted lead length of the LED Driver. Leads should always be
kept short as possible.
