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. Remove the diffuser from the base.
4. Squeeze the gear tray retaining clips (2) to remove the gear tray from the base.
5. The batten can be either ceiling or wall mounted, or suspended. For wall or ceiling installation; mark the position of the
mounting brackets using the distance LF as shown in table below. Use the mounting bracket as a template to mark
mounting bracket screw locations.
6. Secure the mounting brackets (2) to the ceiling/wall using appropriate fixings (fixings suitable for installation into
concrete are supplied, for other mounting surfaces use appropriate fixings depending on the type of building
construction materials used).
7. A pre-drilled cable access hole is available at one end of the batten. If alternative access is required drill the case to
suit the cable gland or conduit to be used. 2 cable sealing bushes (20mm hole) are supplied. Align the base to the
installed mounting brackets and push the base to lock it onto mounting brackets.
Note:
To remove the base from the mounting brackets rotate the gear tray retaining clip assembly a half turn anti-
clockwise. To refit the base repeat above turning the clips half a turn clockwise.
8. Run mains cable as appropriate through the base access hole via a sealing grommet, gland or conduit. Ensure that
the IP rating of the luminaire is maintained.
Note:
If a sealing compound is used, it must be of the neutral cure type.
9. Attach the gear tray to the base via the lanyards provided.
10. Strip 9mm insulation length from mains cable, connect and terminate wires to the terminal block. Be careful with
multi-strand conductors that all the strands are twisted together before insertion into the terminal. Any stray strands
that inadvertently come into contact with their neighbouring terminal will cause undesirable results when the fitting is
powered.
Important note: Protect mains cable with a water proof grommet, gland or bush as it passes through the
cable entry hole to maintain the batten’s IP65 weatherproof integrity.
11. Verify that the battery is connected to the power pack. For Nexus LX or Nexus RF fitting; refer to the data connections
section.
12. Install lamp holders (2 or 4 depending on single or twin lamp) to the gear tray. Ensure there are no cable or wire
obstruction around the gear tray retaining clip slots before clipping the gear tray in place. Fit the appropriate
fluorescent lamp/s as per the size (T5 or T8) of the fitting. (lamp/s not supplied with the fitting).
13. 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 test button to ensure that unit is functional in emergency
mode.
14. Install the diffuser clips to the base and then fit the diffuser, see figure 1.
Data connections - Nexus LX and Nexus RF product range
Important note: 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/NZS2293.
Removal instructions
Before removing the installed fitting, de-energise and lock off the supply circuit.
Note:
There may be 2 actives present,
ensure all power is isolated before proceeding. Remove the diffuser and unclip the gear tray from the base. Disconnect
the battery and then remove the mains cabling from the terminal block.

Connect the data cable to the green connector on the power pack.
When correctly installed no fitting should have more than 2 data cables connected to it.
If you have more than 2 data cables at any 1 fitting, the installation is incorrect.
If this fitting is at the end of a data cable run, a terminator needs to be connected across
the 2 data lines.
If there is an in and out data cable, then the shields should be wound together, folded back
and taped up.
Consult the Nexus user and technical guide for further detail, including product
commissioning.
Nexus RF fitting
Fit the antenna connector through the vacant hole on the base and connect the antenna to
it as shown.
Collect the MAC address, by removing the peel off sticker section and locating it on your
floor plan or spreadsheet.
Note:
Other end of the antenna has been pre-connected to the power pack.
Consult the Nexus user and technical guide for further detail, including product
commissioning.
Nexus LX and Nexus RF fitting
Light sensing clip (fitted with a light dependent resistor - LDR) to be fitted to the lamp.
Position the clip approximately 150mm from the lamp end.
In twin lamp fittings, the light sensing clip should be clipped on the emergency lamp,
which stays on when the test button is pressed.
