Installation instructions
Note: Please read all the following instructions before commencing installation.
It is recommended that the power pack is installed by a competent person ensuring the installation
complies with the necessary Australian standards. ABB accepts no responsibility for injury, damage or
loss, which may arise due to result of incorrect installation, operation or maintenance.
The power pack conversion kit requires an un-switched supply for charging the battery and a switched
supply if the luminaire is being used for maintained operation.
Please ensure to disconnect mains power supply when installing.
1. When placing/installing the control and battery pack into the existing luminaire ensure that they will
operate within their temperature ratings.
2. In general, the control pack is placed close to the ballast to keep wiring short, but far enough away to
prevent overheating.
3. Keep battery away from heat source when installing within the luminaire. The high temperature Ni-
Cad battery supplied is specified and tested for essential characteristics, the performance cannot be
guaranteed with alternative batteries.
4. The LED charge indicator must be positioned in the luminaire where it will be clearly visible during
normal operation. A 6mm hole is required for mounting the LED indicator.
5. The test switch must be positioned in the luminaire where it will be easily accessible to test
emergency operation. A 7mm hole is required for mounting the test switch.
6. The Light sensing clip (LDR) monitors mains on/off lamp condition and is to be affixed on the mains
lamp/tube refer figure 1.
7. Ensure the layout does not interfere with the essential safety features of the original luminaire.
8. Do not obstruct cable entries, mounting points, etc.
9. Installation of a power pack conversion kit will invalidate the original luminaire manufacturer's
compliance and approval. It is the responsibility of the person installing this power pack conversion
kit to comply with Safety, EMC and AS/NZS 2293 design and compliance requirements.
10. It is best practice to avoid running the mains cables next to the power pack output to the lamp to
obtain the best EMC results.
11. Clearly label the un-switched and switched active mains supply in the luminaire.
12. Always use high temperature 105°C insulated wire, or higher grade if originally used in the luminaire.
13. Affix the Nexus RF MAC address label supplied with the power pack on to the fitting in a recognisable
position for recording upon installation.
14. Refer to the Nexus RF user guide for detailed description of all possible LED states and their
meanings.
15. 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 on
the fitting. Press and hold the test button for a few seconds and observe that the emergency lamp
lights up and stays on, until the test switch is released. If the lamp works only momentarily, this
ensures that the connections are correct and the battery requires at least 24 hours to fully charge. If
the lamp does not work at all, check the supply, the connections and the troubleshooting guide at the
end of this document.
16. Once manually checked as per above, the fitting is ready to be communication tested and
commissioned into the Nexus network. Keep the information details of this fitting including exact
location description, DB (distribution board) and CB (circuit breaker) numbering, channel and router
numbering, plan number and cross referencing information as all this will be required for entry into
the database during commissioning. Refer to the Nexus RF user guide for full details.
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.
Wiring connections
• Following below are the wiring connections
to wire power pack as maintained, non-
maintained and sustained. When wiring
power pack to a sustained fitting, the fitting
must be programmed as sustained using
utility tools. Ensure that the stripped wire

Removal instructions
1. Before removing the installed power pack,
switch off the mains supply to the fitting.
2. Unscrew/unplug the unswitched active,
switched active, neutral and output (lamp and
ballast) wire connections from the terminal
block using a suitably sized screwdriver.
3. Undo the test switch nut and remove LED from
the grommet.
4. Unscrew the mains cable connection from the
terminal block and remove sensing clip from
the tube/lamp.
ends are completely inserted into the
terminal block and no bare conductors are
exposed to the metal.
Note: Wiring connections are different if using
electronic or other magnetic ballast.

5. Disconnect the battery plug from the battery
pack and then unscrew the mounting screws of
the power pack.
6. 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.
