Insulation and electric strength testing of luminaires

Electronic LED-drivers can be damaged by high voltage. This has to be considered 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 second. 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 1,500VAC (or 1,414 x 1,500VDC). To avoid damage to the electronic devices this test must not be conducted.

Thermal details and lifetime

Lifetime

Average lifetime 50,000 hours under rated conditions with a failure rate of less than 10 %. Average failure rate of 0.2 % per 1000 operating hours.

The emergency lighting LED driver is designed for a lifetime 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 temperature should be checked and eventually critical components (e.g. ELCAP) measured. Detailed information on request.

89800657 Installation / Wiring

One or more LED modules with a total forward voltage of 48 to 250 V can be connected to the EM converterLED 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 mains LED driver.

89800657 Wiring

89800657 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.

89800657 Wiring guidelines

• 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 REST 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
• REST 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 50Hz 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 considering the max. permitted lead length of the LED driver.

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

Typ. LED current/voltage characteristics

The LED current in emergency mode is automatically adjusted by the EM converterLED module based on the total forward voltage of the LED modules connected and the associated battery. The start of the LED in emergency mode does not result in a current peak.

89800657 LED driver compatibility

The EM converterLED emergency unit use 3 pole technology and is compatible 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 A eff (current rating of the terminals of EM converterLED) and 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 (U-OUT) of the associated LED driver applied to the EM converterLED output is 450 V (voltage withstand between adjacent 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.

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.

89800657 Commissioning

After installation of the luminaire and initial connection of the mains supply and battery supply to the EM converterLED ST the unit will commence charging the batteries for the initial charge time.

The recharge occurs also if a new battery is connected or the module exits the rest mode condition. The following automatic commissioning duration test is only performed when
a battery is replaced and fully charged.

89800657 Testing

Commissioning test

A full commissioning test is carried out automatically after permanent connection of the supply for 5 days. The easy commissioning feature will set the initial test day and time to ensure random testing of units.

Functional test

Functional tests are carried out for 5 seconds on a weekly basis under the control of the Micro controller. Initiation and timing of these tests is set during the commissioning of the luminaire.

Duration test

A full duration test is carried out yearly to check the capacity of the batteries.

For a full description of commissioning and test features please refer to application notes.

Test switch

An optional test switch can be wired to each EM converterLED ST. This can be used to to:

• Initiate a 5 seconds function test: press 200 ms < T < 1s
• Execute function test as long as switch pressed: press > 1s
• Reset selftest timer (adjust local timing): press > 10 s

Timer reset functionality

The timer for function and duration test can be set to a particular time of the day by either pressing the test switch for longer than 10 seconds or cycling the unswitched line supply 5 times within 1 minute. The timer adjustment will enable the test start time to be defined manually at time in day when the timer was reset.

It will also disable the adaptive test algorithm thereby forcing the unit to perform the test at the same time rather than it being defined by the adaptive algorithm. This function will only work provided the interval time is greater than zero (automatic test mode enabled).

The delay timer value set when the unit was commissioned will be reloaded in order to randomise the tests between adjacent units. The factory programmed delay offset (1 – 28 days) will be loaded after the reset into the delay timer for the function and duration test in order to randomize the tests between adjacent units.

Rest Mode / Inhibit Mode

Emergency operation is automatically started when the mains supply is switched off. If the Rest Mode is activated, the discharging of the battery will
be minimized by switching off the LED output.

If the Inhibit Mode has been activated before the mains supply is switched off, Rest Mode will be automatically activated if the mains supply is switched off within 15 minutes. Rest Mode and Inhibit Mode can be initiated by applying a short pulse between 9.5 and 22.5 VDC in amplitude for a period of 150 to 1,000 ms.

This pulse shall be applied to terminals marked Rest. After a mains reset the EM converterLED ST exits the Rest Mode. Rest Mode and Inhibit Mode can both be disabled by applying a voltage pulse of 1,000 to 2,000 ms to the terminals marked as Rest to send the RE-LIGHT/ RESET INHIBIT command.

Self-test emergency LED modules are intelligent conversion kits that automatically convert standard LED luminaires into legally compliant emergency lights. They contain a battery and control circuitry, and they automatically perform routine, scheduled tests to verify functionality during power outages.

How They Work

Automatic Testing: Modules periodically simulate power failures to test the battery and LED operation without human intervention. Standard schedules include monthly function tests (e.g., ~30 seconds) and annual full-duration tests (e.g., 3 hours).

Visual Diagnostics: They feature a multi-colored status LED (usually green/red) that alerts users to faults like a degraded battery or a disconnected lamp.

Maintained vs. Non-Maintained:

Maintained: The LED is on during normal operation and stays on (using battery power) during a power failure.

Non-Maintained: The LED stays off during normal operation and only turns on when the main power fails.

Key Benefits

Compliance: Simplifies meeting fire safety regulations (such as BS 5266 in the UK).

Cost-Effectivity: Eliminates the need for manual monthly inspections and annual key-switch testing, which saves labour and minimises business disruption.

Easy Installation: Most universal modules are compact plug-and-play units equipped with internal lithium-ion or NiCd batteries, designed to fit easily inside the luminaire or a ceiling void.
