3.5 Wiring guidelines
• The LED terminals, battery, indicator LED and test switch terminals are clas-
sified as SELV (output voltage < 60 V DC). Keep the wiring of the input termi-
nals separated from the wiring of the SELV equivalent 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 and DALI 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 0.8 m
• DALI terminals are mains proof
• 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 emergency
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 to the LED module must not be exceeded. Note that
the length of the EM converterLED leads to the LED module is added to the
length of the leads from the LED Driver to the EM converterLED module when
considering the max. permitted lead length of the LED Driver.

Note: The length of LED leads to the LED module must not be exceeded. Note that the length
of the EM converterLED leads is added to the length of the leads from the LED Driver to the EM
converterLED module when considering max. permitted lead length of the LED Driver. Leads
should always be kept as short as possible.
3.7 Use of different phases
The use of different phases for switched line and unswitched line is allowed.
When using different phases, the unswitched line must fail if the switched
line fails. This is required to assure correct switching into emergency mode. It
can be realised with a relay.
