1.1 Glow-wire test
according to EN 61347-1 with increased temperature of 850 °C passed.
1.2 Insulation and electric strength testing of luminaires
Electronic LED-Drivers can be damaged by high voltage. This has to be consid-
ered 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 500VDC for 1 sec-
ond. This test voltage should be connected between the interconnected phase
and neutral terminals and the earth terminal. The insulation resistance must be
at least 2 MΩ.
As an alternative, IEC 60598-1 Annex Q describes a test of the electrical
strength with 1,500 VAC (or 1,414 x 1,500 VDC). To avoid damage to the electronic
devices this test must not be conducted.
2. Thermal details and life-time
2.1 Life-time
Average life-time 50,000 hours under rated conditions with a failure rate of
less than 10 %. Average failure rate of 0.2 % per 1000 operating hours.

3. Installation / Wiring
3.1 Wiring diagram
One or more LED modules with a total forward voltage of 40 to 97 V can be con-
nected to the EM converterLED 90V module. These LED module(s), marked with
“Emergency” are operated in emergency mode from the associated battery. In
normal mains mode all LED modules are operated by the LED Driver from the
mains supply.
Use of the test switch:
For checking the device function press the test switch for a minimum of 3
seconds.
Meaning of marking
Double or reinforced insulation for built-in electronic LED Drivers. The control
gear relies upon the luminaire enclosure for protection against accidental contact
with live parts.
The emergency lighting LED Driver is designed for a life-time stated above
under reference conditions and with a failure probability of less than 10 %.
The relation of tc to ta temperature depends also on the luminaire design.
If the measured tc temperature is approx. 5 K below tc max., ta tempera-
ture should be checked and eventually critical components (e.g. ELCAP)
measured. Detailed information on request.

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 Ø1 mm
release tool
3.5 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 0.8 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.
1Note: 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.

5.4 LED Driver compatibility
The EM converterLED emergency unit use 3 pole technology and is compa-
tible with most LED Drivers on the market, however it is important to check
that the rating of the LED Driver does not exceed the values specified below:
• The max. allowed output current rating of the associated LED Driver is
2.4 A peak (current rating of switching relays of EM converterLED)
• The max. allowed inrush current rating of the associated LED Driver is
60 A peak for 1 ms or 84 A for 255 μs (inrush current rating of switching
relay of EM converterLED)
• The max. allowed output voltage of the associated LED Driver applied to
the EM converterLED output is 450V (voltage withstand between adja-
cent contact of the single switching relay of the EM converterLED)
• The max. allowed LED load of the associated LED Driver is 150 W in
operation. The load must be an LED module.
Check compatibility with short function tests (duration of several seconds).

Duration Usage duration link
Emergency lighting LED Driver supplied with duration link in 3 hours
position.
The position of the link will only be read on first power up. If it is changed
afterwards both the battery and mains supply must be disconnected for
10 seconds to enable the EM converterLED to read the new link position on
reconnection of the battery and mains. It will lead to a false battery failure
indication if the link is changed after installation without this reset.

1Automatic recharge when battery voltage falls below 3.4 V. Charger o (0 mA) when battery voltage exceeds 3.6 V.
Note: Battery protected against operation at excessive temperatures (charging stopped when battery cell temperature < -5 °C or > 60 °C).
The emergency lighting LED Driver will recharge the battery normally after running the test of 61347-2-7 CL 22.3 (abnormal operating conditions).
2The battery will not be charged below 2.0 V.
7.5 Safety
7.5.1 Deep discharge protection
When the battery remains connected without charging for a long period of time
after the battery cut off of the driver the battery voltage can still drop. To make
sure the cells are not damaged by this voltage drop, the battery protection
prevents the battery from further discharge below 2.0 V.
7.5.2 Overcharge protection
If in case of an error or the use of a wrong driver the battery gets overcharged
the battery protection will disconnect the battery from the driver at a voltage of
3.9 V. A discharge of the battery is still possible after the protection circuit was
triggered to guarantee emergency operation.
7.5.3 Short-circuit protection
In case of a short circuit the battery protection opens the connection to the
driver and the output is therefore free of voltage. The output will be reactivated
again when the short circuit is removed.
7.5.4 Overtemperature protection
The battery is protected against temporary thermal overheating. If the tempera-
ture limit is exceeded the further charging of the battery is no longer possible.
The temperature protection is activated below approx. 0 °C and above approx.
+60 °C. The discharging of the battery is still possible to guarantee emergency
operation.

8. Miscellaneous
8.1 Maximum number of switching cycles
EM converterLEDs are tested with 50,000 mains switching cycles of the
associated LED driver.
8.2 Battery replacement
After a battery replacement and a subsequent full charge cycle (24 h) a
duration test is mandatory to prove that with the new battery the rated
duration is achieved.
