Installation instructions
1. Remove the unit from the packing box and inspect it for damage or imperfections. If any damage is found, do not
install the unit, but replace it carefully into the packing box and notify the ABB product support hotline in Australia on
1300 666 595.
2. If all looks okay, installation can proceed.
3. Take the mounting bracket and whilst holding it into place against the ceiling or wall, use a pencil to mark the position
of the screw holes (at A or B in figure 2) and cable entry position through the bracket onto the ceiling or wall as
appropriate. Make sure to allow at least 50mm of free space to the right hand side of the final location of the unit to
allow for the sliding function of attaching the unit to the mounting bracket. If need be, turn the bracket around and
swap the diffuser with the back plate to permit room for inserting and removing the unit from the mounting bracket.
Orient the bracket in such a way as to make the LED and push button readily visible and accessible when the unit is
installed.
4. Remove the bracket to reveal the pencil marks and if the cabling is to be concealed, drill a 20mm hole for the cable
entry prior to installing the bracket. Make sure the mounting screw locations are into solid material and strong enough
to support the weight of the complete unit, (approx 2kg: build-up, strengthen or support the mounting material if
necessary) and attach the bracket. Because of the wide variety of building construction materials and the wide variety
of screw fasteners appropriate to each type, mounting screws are not provided with the unit. If appropriate and safe,
drill and use your own fixing holes in the mounting bracket to suit the individual installation location and structural
support needs of the unit, taking care not to obstruct the fitting slide entry.
5. Run the cables in the ceiling or wall space as appropriate or surface mounted in conduit and through the cable hole
into the bracket. Strip, connect and terminate the cables as indicated in figure 1. Ensure that the double insulation
of the cable/s passes completely into the terminal block enclosure so that no single insulation is exposed when the
cover is in place. The hole plug set includes a suitable bush to mechanically protect the cable as it passes through
the opening in the mounting bracket. Likewise, the single insulation of the conductors should run right up to the metal
edge of the terminals leaving no bare conductors outside of the terminals. Be careful with multi-strand conductors that
all of the strands are twisted together before insertion into the terminal. Any stray strands that inadvertently come into
contact with their neighbouring terminal or the metal frame of the fitting will cause undesirable results when the fitting
is powered.
6. Attach the unit to the mounting bracket by aligning the top left hand end of the unit (the end without the protruding
electrical connecting metal lugs) with the large cut-away slot towards the left hand end of the bracket. Slip the left
hand end of the unit up into the slot in the left hand end of the bracket (step (1) in figure 2) and hold the unit horizontal
to and parallel with the bracket. It should be approximately 50mm to the right of its final destination. Simply slide the
unit (step (2) in figure 2) 50mm to the left along and into the bracket to engage the connections and the locking tab.
Once in place, the unit cannot be removed from the bracket without the use of a tool (a small screwdriver) to push in
the locking tab at ‘D’ in figure 2. Ensure the correct pictograph inserts have been attached to the diffuser assembly.
7. Once powered up, the normal AC LED light source will energise and remain lit until the power supply fails. The
emergency function of the light fitting will only operate when the normal lighting power supply fails or when somebody
presses the manual test button located on the front of the unit. Red LED indicates that the power is connected and
the battery is charging.
8. Check the operation of the unit to ensure that the installation was successful. When powered up, allow a few minutes
to give the battery a small charge, then press the manual test button located at the front face of the unit. Hold the test
button in for a few seconds and observe the operation of the LED light source switching from mains to the emergency
mode. If the LED light source on emergency mode works momentarily, that’s okay. Try again in a few more minutes
because if the battery was completely discharged, it may take a little time to charge up enough to operate even
momentarily. After this time, press the test button again, and if the LED light source does not work at all, check the
supply, the connections and the trouble shooting guide at the end of this document.
Important note: If installing this product into an early version ceiling bracket, first remove the 2 hole blanking
plugs on the front face of the bracket and replace with the short hole plugs provided with the product.
Removal instructions
1. Gently insert a small screwdriver into the slot (at ‘D’ in figure 2) on the front of the bracket towards the right hand end
of the fitting, to ease the locking tab into the fitting and away from the bracket.
2. The unit is then free to slide to the right along the bracket for about 50mm, at which time the slots line up and it can
be lowered away from the bracket, allowing the two to separate.
3. The unit will automatically switch into emergency mode because it has been removed from the power supply. It will
stay on emergency until such time as the battery cut-off threshold is reached or it is reconnected back onto the power
supply, whichever happens first.
4. When the unit is reconnected to the supply, it will need time to recharge its battery before it will be capable of a
full length discharge again. The ability of the unit to operate on emergency is determined by the age, charge level,
operating temperature conditions and environmental circumstances of the battery in the unit.
Testing precautions
Once the fitting is permanently connected to the mains supply, a commissioning discharge test as required in
AS/NZS2293.2 must be carried out. You will need to allow 24 hours for the battery to fully charge prior to conducting
this test, presently (at the time of writing), the standard requires that fittings operate in emergency mode for a period not
less than 2 hours for their commissioning test and for not less than 90 minutes thereafter (it is required that 6 monthly
discharge tests be carried out). You will need to keep the records for the commissioning test and enter them into the
building emergency services logbook or via other recording methods as allowed by AS/NZ2293.2.
Construction sites
Continuously switching of the mains power supply that is connected to emergency light fittings during the construction
phase of an installation will cause these fittings to discharge and charge their batteries many times over a short period;
this can shorten the life of the battery and will also result in shortened emergency lamp life. ABB does not recommend
such practices and may not honour the warranty on batteries when they are subjected to such harsh operating
conditions. Emergency light fittings are designed to be discharge tested once every 6 months as per AS/NZS2293.2,
subjecting the product to repeated discharge or charge cycles is regarded as an abuse of the fittings.
− Maintained fittings are design for permanent illumination:
connect incoming unswitched active, neutral and earth to
terminal marked USA, N and E respectively.
− Data connection for Nexus LX product installation:
The same colour wire from each data cables connects to
the terminal .
The other colour wire from each of the data cables
connects to the terminal marked -.
When connected, replace the terminal block cover so that it
clicks and locks into place.
No mains or mains carrying cables are to be connected to
the data terminals or cables.
