If a battery capacity failure was indicated before the light fitting was switched off, a operational life test
will be carried out 24 hours after the power supply is re-established. The subsequent operational life
tests will be conducted at 52 week intervals.
If no battery capacity failure was indicated before the battery was changed, the interruption of the
energy supply to the emergency light unit will result in a operational life test between 5 and 28 days
later. The subsequent operational life tests will be conducted at 52 week intervals.
Version with battery box:
Loosen the locking screws of the battery box.
The emergency battery is located in the lid of the battery box. Take care when opening it.
Press down the catch on the plug connection and pull the connector of the battery cable out of the
socket.
Insert the protective cap hanging on the connector of the battery cable into the battery connector.
Loosen but do not fully unscrew the locking screws of the battery fixing bracket.
Slide the fixing bracket in the keyhole towards the hinge until the battery is released.
Remove the emergency battery from the lid.
Insert a new emergency battery into the lid.
Return the battery fixing bracket to the original position and screw down. Check that the battery is
positioned securely.
Remove the protective cap of the battery connector.
Attach the battery connector to the socket in the battery box. Check the catch mechanism of the
plug connection.
Alert the emergency light unit to the presence of a new battery:
Open and close the lid of the battery box twice within a 60-second period. Opening and closing the
case must occur within 10 seconds of each other.
If this procedure is done correctly, immediately after the battery box is closed for the second time,
the signal LED will display an acknowledgement light. The five-second long red-green
acknowledgement light confirms that a operational life test will be conducted 12 hours later.
Close the lid of the battery box with the screw plug.
Should a battery capacity fault be present when the acknowledgement light is displayed, more
operational life tests will then be carried out at 52 week intervals. If no fault was detected in the battery
capacity, the interval until the next regular operational life test is unaffected.

Replacement of the LED boards and of the emergency light unit has been described in the separate
