Isolate the luminaire from the mains and battery supply as described above. Disconnect the red and black wire that leads from the ballast to the
microswitch terminal block at the terminal block. (Note that the positions of the wires are marked on the ballast housing cover for re-assembly.)
Loosen, but do not remove, the bolts securing the battery tube brackets. Now remove the clips on the ballast housing lid securing straps and
remove the battery assembly by moving it first one way (slots in the mounting brackets allow movement) then the other. The battery tube/ cable/
ballast housing cover assembly can now be fully removed to a safe working area before carrying out any work on it. It is important that a
replacement assembly should be fitted immediately. The luminaire must not be left in the open condition and must not be energised from the
mains when open.
REPLACING THE BATTERY.
Remove the battery assembly as described above. Remove the two screws at the cable end that secure the bracket and plastic moulding to the
tube. Carefully withdraw the end moulding from the battery tube, ensuring that the internal wiring is not stressed. (A slight rotation, a few degrees
either way, can help removal. Do not twist in one direction only as the wires may become damaged, short circuit the battery and blow it’s fuse.)
Disconnect the battery wires one at a time by inserting a screwdriver through the holes in the side of the moulding. As each wire is removed it
should be insulated. Failure to do this may result in a short circuit.
Remove the moulding at the other end of the tube to expose the fuse assembly. The battery may now be removed from the tube. Do not use the
battery wires to aid removal.
Replacing the battery is the opposite procedure, but when replacing the battery in the tube it is important to ensure that the sponge rubber strips
are inserted around the inside of the tube at either end. The fuse should also be fitted so that the flat side locate correctly in its moulding. Finally
ensure that the new battery leads are connected to the correct terminals in the end moulding. (Red to + and black to -)
REPLACING THE BATTERY FUSE.
Remove the battery tube / cable / ballast cover assembly, and expose the fuse as described above. Care must be taken when handling /
removing the fuse connections to prevent the risk of short circuit. Remove the soldered receptacles from each terminal blade of the fuse in turn
and fit to a new fuse assembly. The receptacles must be soldered in place on the new fuse to achieve the approved connection. Re-assemble
the battery tube as described above.
REPLACING LAMPHOLDERS.
The monopin lampholders form part of a flameproof enclosure and must be replaced if damaged. To gain access to the lampholders remove the
lamp envelope and ballast housing cover as described earlier. To remove a lampholder, push the lampholder retaining plate against the
lampholder spring, rotate through 90°C and release. The lampholder can then be withdrawn and its cable disconnected. Replacement is a
reverse of this procedure.
REPLACING THE ELECTRONIC BALLAST.
Disconnect from the mains supply (make sure both Live and Live Switched supplies are isolated). Remove the ballast housing cover and
suspend from its straps. Disconnect the mains wires from the ballast terminal block and also the battery red and black leads from the microswitch
terminal block. Disconnect the earth bonding cable from the connection on the electronic ballast (leave attached to the gland plate). Remove the
lampholders as described above. The electronic ballast can now be removed by slackening two screws at one end of the unit and the two nuts at
the other end. The three cables from the electronic ballast can now be removed from the lampholders. Replacement is a reversal of this
procedure.
REGULAR MAINTENANCE AND INSPECTION
All luminaires and installations, including cable, conduit and other associated systems which make up an installation must be maintained in such
a way to ensure the integrity of the protection to which it was designed to have. BS5345 makes particular reference to this subject,
recommending initial and periodic inspections, with suitable recording of
OPTIONAL BATTERY MANAGEMENT SYSTEM
The Optional battery management system (if fitted) monitors the battery capacity and can detect fault conditions within the system. It is pre-
programmed to automatically test and assess the condition of the battery at pre-set intervals, normally every three months. The status of the
system is indicated by green and red LEDs on the ballast enclosure, as shown below.
LED STATUS
GREEN (CONTINUOUS) SYSTEM HEALTHY:
THE BATTERY WILL BE CHARGED WITH ENOUGH CAPACITY TO MEET EMERGENCY DURATION TIMES.
GREEN / RED FLASHING
ALTERNATELY
SELF DISCHARGE TEST IN PROGRESS. (ABOUT EVERY THREE MONTHS.)
RED (CONTINUOUS) SYSTEM MAY HAVE A FAULT:
IF A MAINS FAILURE OCCURS THE LUMINAIRE WILL NOT PROVIDE THE MINIMUM DURATION OF
EMERGENCY LIGHTING
