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.
3.4 Loose wiring
Loosen wire through twisting
and pulling or using a Ø 1 mm
release tool
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 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.
• Separate LED leads 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.
• Route the secondary wires (LED module) in parallel to ensure good EMC
performance.
• Maximum lead length for the Test switch and Indicator LED connection is
1 m. Separate the test switch and Indicator LED wiring 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.
• Protect the wiring against short circuits to earth (sharp edged metal parts,
metal cable clips, louver, etc.) to avoid the damage of the control gear.
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 route the switched and unswitched 50 Hz supply wiring
as short as possible and keep it as far away as possible from the LED leads.
Through wiring may affect the EMC performance of the luminaire.
Do not exceed the max. length of LED leads to the LED module. 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 conside-
ring 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.
