Schematic Showing Driver & Splitter
Problem Probable Causes Test & Remedy
Constant Current System
System is dead - no light
output from LED’s
Mains supply o Check supply and reinstate.
Loose mains plugs Check plugs.
Loose DC output wire or
connection Check all connections.
Splitter LED channel not
terminated
Check all splitter channels have LED
fittings plugged in or have continuity
jumpers fitted. Plug in LED’s and/or jumpers
Single failed LED
With power ON, carry out one of tests
detailed in fault finding guide. Replace
faulty LED.
More than one failed LED
Gradually replace LED plugs with
continuity jumpers until LED’s light. Do
not reduce the number of LED’s plugged
into the splitter below the driver minimum
Driver failed
Check output with DVM. With power ON
and no LED’s lit, DC voltage output to
LED’s should be at maximum
Cable between driver and
splitter failed
With power ON and splitter cover
removed, put DVM across input to splitter.
DC voltage input to splitter (allowing for
volt drop in cable) should be at
maximum. If no voltage fault find and/or
replace cable.
Constant Current System
Some LED’s not working
Short circuit - damages cable
between LED and splitter Repair or replace.
LED short circuit Replace LED and cable.
Constant Current System
LED’s on full illumination
- not dimming
Faulty or wrong connection at driver
or dimmer control box
Check driver and dimmer connections.
Replace/repair as necessary.
Faulty dimmer potentiometer or
damaged dimmer control cable
Remove dimmer control cable from
dimmer. Check continuity of cable and
dimmer pot. Replace/repair as necessary.
Failed driver Replace driver.

QUICKSTART GUIDE
UFO MBL2 LED DOWNLIGHT
Rev. C1
E360312

WARNING – Connecting constant current LED fittings to a driver with excessive
minimum voltage output will result in catastrophic damage to the LED devices
within these fittings. Always check the minimum output voltage of the driver and
ensure that based on 3.2V per LED an adequate number of fittings are connected
prior to powering up the system.
WARNING – Hot swapping constant current LED fittings to a driver may result in
catastrophic damage to the LED devices within these fittings. Always power down
the driver before adding a constant current LED fitting.
These LED fittings are suitable for indoor/dry areas and must not be installed in
damp or wet conditions.
IMPORTANT
THIS PRODUCT MUST BE INSTALLED IN ACCORDANCE WITH THE APPLICABLE
INSTALLATION CODE BY A PERSON FAMILIAR WITH THE CONSTRUCTION AND
OPERATION OF THE PRODUCT, ITS COMPONENT PARTS AND THE HAZARDS
INVOLVED.
ELECTRICAL WIRING AND CONNECTION MUST BE CARRIED OUT BY A SUITABLY
QUALIFIED PERSON OBSERVING ALL LOCAL AND STATUTORY ELECTRICAL
REGULATIONS.

Safety Guidelines
MBL2 Articulated LED Downlight
Connections
The fittings are suitable for use with a constant current driver only.
• 350mA or 500mA output (depending on territory)
• Rated Class 2 or LPS
• Approvals UL/CE
• Protection - Short Circuit/Over load/ Over voltage
• Minimum voltage rating not to exceed the number of LED fittings connected
• Number of LED fittings connected not to exceed the Maximum voltage rating
There are 4 electrical connections required before connecting the system to the
mains.
1. Connect ALL LED fittings to the input channels of the Series Splitter.
2. Make sure ALL unused Series Splitter channels have continuity jumpers fitted
3. Connect the Series Splitter directly to the Constant Current Driver.
4. Connect the electrical supply to the driver. Switch on power, the LED fittings will
illuminate.
If no light is produced, consult the TROUBLESHOOTING section.

Introduction
Thank you for purchasing these low voltage UFO LED fittings.
Please read these instructions fully before installing your LED fittings, connecting
your LED fittings to the splitter/driver and before connecting your display system to
the electrical mains. Please keep this manual for future reference.
The UFO splitters are supplied with removable continuity jumpers. Retain these
jumpers for future use.
Please refer to the specific section within this manual to ensure correct associated
splitters/drivers/power supply units are used for your fittings.
These LED fittings are only mains dimmable with an appropriate mains dimmable
constant current driver.
These LED fittings operate on a constant current driver low voltage supply.
Constant current and constant voltage LEDs cannot be intermixed on the same
driver. Please refer to the specific section within this guide for wiring/connection
guidance.

MBL2 Downlights are constant current LED fittings.
Before assembly, unpack the shipment and check that all components are included
before commencing your installation. It is recommended that the system be planned
prior to work commencing to ensure the Series Splitter is centrally located to match
LED fitting cable lengths. Fit all MBL2 fittings in place as detailed below.
