Emergency lighting units
EM converterLED
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.
8.3 Mains-connected transformers
The EM converterLED does not contain mains-connected windings of trans-
formers.

Technical Data
Lifetime declarations are informative and represent no warranty claim.
No warranty if device was opened.
7.9 Storage, installation and commissioning
Relevant information about storage conditions, installation and commissioning
are provided in the battery datasheets.
7.8 Wiring batteries
To inhibit inverter operation disconnect the batteries by removing the
connection at battery side.
For further informations refer to corresponding battery datasheet.
7.7 Safety
7.7.1 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.
7.7.2 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.
7.7.3 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.
7.7.4 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.
