Installation instructions
1. 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 fitting to allow for the sliding function of attaching
the fitting 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 fitting 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 fitting is installed.
2. 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 fitting, (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 fitting. 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 fitting, taking care not to
obstruct the fitting slide entry.
3. 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 plate 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
of the metal frame of the fitting will cause undesirable results when the fitting is powered.

5. Fit the diffuser assembly to the body of the fitting (if not already in place). Attach the fitting to the
mounting bracket by aligning the top left hand end of the fitting (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 fitting up into the slot in the left hand end of the bracket
(step (1) in figure 2) and hold the fitting horizontal to and parallel with the bracket. It should be
approximately 50mm to the right of its final destination. Simply slide the fitting (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 fitting 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.
6. 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
fitting. Red LED indicates that the power is connected and the battery is charging.
• Maintained fittings are designed for
permanent illumination: connect incoming
unswitched active, neutral and earth to
terminal marked USA, N and E respectively.
7. Check the operation of the fitting 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 fitting. 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 troubleshooting guide at the end of
this document.

Important: 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.
Data connections
Nexus LX fitting
• The same colour wire from each data cables
connects to the terminal marked +.
• The other colour wire from each of the data
cables connects to the terminal marked -.
Important: 24 hours is required to allow the fitting battery to reach full capacity, ie: prior to a
discharge test. As the installer, it is your responsibility to conduct the initial discharge testing of
the installed fitting. Refer to AS/NZS 2293.
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 fitting 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 fitting will automatically switch into
emergency mode because it has been
removed from the power supply. It will stay on
• 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.
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 fitting 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 fitting to operate on
emergency is determined by the age, charge
level, operating temperature conditions and
environmental circumstances of the battery in
the fitting.
