varies. This is an image depicting the range of
motion on a standard mobile mount version.

Page 8of 43
3.2 Battery Back-up (Optional)
The SL730 series has the capability of using a battery back-up system.
The battery should be conditioned before being used for the first time. Battery conditioning
involves removing all the charge from the battery. Batteries should be conditioned regularly.
Condition a battery when the device is stored for long periods, or when the charge becomes
noticeably shorter.
Follow the steps below to condition a battery:
1. Disconnect the battery from the light.
2. Attach the battery in need of conditioning to a suitable electrical supply.
3. Charge the device uninterrupted for up to 10 hours.
4. Disconnect the electrical supply and re-attach the battery to the light, allow the light
(while disconnected from its primary power source) to run on the battery until it
shuts off.
5. Charge the battery until full charged again.
6. The battery is now conditioned.
Batteries can deteriorate over time, meaning a reduction in their performance.
To check the performance of a battery, follow the steps below:
1. Charge the battery uninterrupted for 10 hours.
2. Disconnect the mains supply to the light and allow it to run on the battery until it
shuts off.
3. The operating time of the light reflects the condition of the battery. If the operating
time is significantly lower than when first purchased despite conditioning it, you will
need to replace the battery.

3.3 Control Panel
The SL730 uses a control panel on the side of the head for adjustment of the light settings.
Use the power switch to switch the light on, or off.
Next to this switch are two sets of controls: ‘Intensity’ and ‘Colour’
The plus and minus buttons in each corresponding section turn the setting up or down
respectively.
For the Intensity control, use the plus button to increase the intensity (brighter) and the minus
button to lower the intensity (dimmer).
Similarly, for the Colour control, use the plus button to increase the Colour Temperature and
the minus button to lower the Colour Temperature (range between 3,600 and 5,500 Kelvin)
3.4 Adjusting the Light head
The SL730 is secured using a large white, balanced and adjustable arm. The head itself has
forward and backward motion through the hinge joint connecting the head to the tertiary arm.
The head can be adjusted through use of the handles located on the side of the head.
Care should be taken not to violently or forcibly adjust the head as this may
damage the light.

4.2 Mobile Mounted Version
Please refer to the packing list earlier in the manual (section 1.4, page 5) before commencing
the assembly procedure, to ensure that all parts can be located. Each screw required should
already be fitted into its designated hole –ensure to remove these when reaching each
relevant section within the below instructions.
The mobile base assembly will come supplied with the wheels already fitted. Ensure to apply
the brakes before commencing the assembly process, to prevent movement and aid assembly.
Fig.1 Fig.2
Within your kit you should identify two pieces of the upstand. Feed the wire (see fig.3) from
the mobile base through the shorter of the two pieces, noting that the end with the four
screw holes should be uppermost, then place this part in the circular housing in the top of
the base. Do not secure this part yet.
Fig.3 Fig.4
Locate the second (longer) piece of the upstand with the curved end uppermost, and remove
the four screws from the straight end. Then, connect the cable from the first piece of the
upstand to the cable trailing from the bottom of the second piece of the upstand. (see fig.5).
Then, slot this piece into the first part of the upstand that we assembled earlier whilst
feeding the excess cable inside the longer tube.

4.3 Ceiling Mounted Version
The ceiling structure must be capable of handling up to a 500kg load.
The procedures below are detailed to a high level however If in doubt please consult a
qualified electrician.
Minimum Room Requirements
The SL730 Series ceiling mounted light has a standard fixing
height of 2.4m. The design works off a fixed plate system
and has a large vertical motion.
Maximum Room Requirements
Please note, if the ceiling / fixing point of the light is
above 2.5m then a customised ceiling mount will be
required, (please contact Daray for more information).
If a suspended ceiling is in the room, you will need to
construct a platform down to the required fixing height.
Live Electric Circuitry
All personnel working around live circuitry should be
qualified and following proper procedures
Heavy or Difficult fittings
Fitting the ceiling plate can be difficult and aspects of the
fitting may require more than one person; this work should
only be attempted by appropriate and competent personnel.
Existing Environmental Factors
When fitting, considerations have to be taken for existing
services such as; fire alarms, vents, lights, etc. along with
interior ceiling construction and any surrounding hazard.
Environmental Responsibility
Once our products are installed all packaging should be
disposed of appropriately and recycled where appropriate
and in accordance with local governing regulations.
The normal life span of the SL730 series is up to ten years.
We recommend the equipment should be discarded and
recycled when reaching the end of its life.

Page 16 of 43
These instructions are based on the assumption of a fresh fit into a room with no previous
lighting structures. With installations onto sites with equipment already in place, we
recommend that the previous lights’ mounting plates be removed and the new ones fitted as if
into a fresh fitting.
After concluding the structural stability of the ceiling structure it will be necessary to assess
the construct and decide on the best course of action for installing the ceiling plate. There are
various different methods for loading the plate onto the ceiling, below are various example
methods that can be used.
4.3.1 Attachment methods and void suspension
The ceiling mount is split into 2 parts, the fixing plate and the ceiling plate. Please note, the
recommended room height allowed for fixing requires the bottom of the ceiling plate to be no
lower than 2.4m.
Bolted Directly into a structural slab and secured with chemical bonding
This is our primary choice for mounting our lights to the ceiling structure, appropriate rawl
bolts and chemical bonding should be used to secure the fitting.
Bolted to a Uni-strut Construct
When using a uni-strut construct for mounting the ceiling plate, you should ensure that the uni-
strut is cross braced to ensure it is secure and does not move.
Welded to structure
The fixing plate is the component that would be welded to the structure; any welding must be
assessed to be capable of handling a 500Kg load.
System anchored to composite deck
A customised composite deck could be used either in conjunction with or as a replacement to
the fixing plate. Any substitute parts must meet safety standards and be assessed by a
competent structural assessor. The composite deck is designed to spread the weight of the light
over an enlarged area.
System bolted to structure
This system requires prior planning during the base construction phase of the ceiling above,
bolts should be fed through the metal ceiling prior to the concrete base being poured. These
bolts should be based on the fixing plate layout in section 3.5.1
4.3.2 Lighting configuration
Dependant on the choice of attachment method, and whether the light is being attached in a
void or directly onto an open surface ceiling; custom mounting aspects may be required.
Daray’s standard mounting recommendation is to have the fixing plate directly bolted into the
structure of an open surface ceiling when possible.
Ultimately the mounting method used is the responsibility of the project engineer or fitter. This
includes the specification of attachment hardware, lateral bracing and the suitability of the
surface to be fixed to.

Page 17 of 43
4.3.3 Installing the Ceiling plate
The location of the light should be decided by the end user / project manager or through
schematical drawings.
Once the location has been decided it will be necessary to first mark the location of the
fixing/ceiling plate.
As shown, fitting your ceiling plate requires bolts be inserted directly into the ceiling super
structure. The ceiling plate can however be fitted to an optional fixing plate instead. The fixing
plate would then attach to the ceiling super structure instead of the ceiling plate.
Whichever fixing method used; it is highly advisable that the plate being fixed to the ceiling, is
secured with a minimum of 4 bolting points to ensure a complete and sturdy fit.
Once the fixing plate is fitted and secured, you will need to attach a locking nut to each bolt
protruding from the fixing plate before attaching the ceiling plate. Now fit the ceiling plate to
the fixing plate by sliding the fixing points onto the bolts from the fixing plate and attach a 2nd
nut to the bolts.

Dimensions
Once the ceiling plate has been fitted, it will be necessary to ensure that it is balanced on the
vertical plane. This can be achieved by adjusting the 2nd level of nuts (the adjusting nut). Once
this adjustment has been done tighten the 1st level of nuts down to the ceiling plate to lock the
plate into position.
After any adjustment it will be necessary to check that all fixings are still sound and that
locking nuts are tight.

4.3.4 Wiring and transformer layout
Before working on electrical connections please make sure that the power to the
light is switched off at the source and secured so that it will not be turned on
during your work.
The mains power supply should meet IEC60245-1 requirements and should be
fitted with a fixed master switch. (The switch should meet IEC328 requirements
and the directional movement parts of the switch should meet IEC447
requirements and the symbols should meet IEC60601-1 requirements.)
Ideally the cable used to power the light should be of a 1.5mm twin and earth type. Daray
recommends that the power supplied uses an earthed switched fused spur, protected with a 3
amp fuse.
Fig.1
The above wiring is for modern wiring applications (post 2000). On completion of the wiring,
the next stage will be attaching the suspension arms to the ceiling mount.
Fig.2
The wiring should be as follows:
Live terminal brown wire.
Neutral terminal blue wire.
Earth terminal green/yellow wire.
