The lighting fixture can be only used indoors, IP20.
The lighting fixture is not designed or intended to be mounted directly on to inflammable surfaces.
The lighting fixture is only intended for installation, operation and maintenance by qualified personnel.
Do not project the beam onto inflammable surfaces, minimum distance is 5m. 5m
Avoid direct exposure to the lightfrom the lamp.The light is harmful to eyes.
Do not attempt to dismantle and/or modify the lighting fixture in any way.
Electrical connection must only be carried out byqualified personnel.
Before installation, ensure that the voltage and frequency of power supply match the power requirements of the lighting fixture.
It is essential that each lighting fixture is correctly earthed and that electrical installation conforms to all relevant standards.
Do not connect this device to any other types of dimmer apparatus.
Make sure that the power-cord is never crimped or damaged by sharp edges. Never let the power-cordcomeintocontactwithothercables.
Only handle the power-cord by the plug. Never pull out the plug by tugging the power-cord.
When the lighting fixture is hanged to a high place, please use a safety cord provided to pass through the lighting fixture’s handles as a
secondary safety fixing for safety seasons. For details, refer to “INSTALLTHE LIGHTING FIXTURE “section.
Exterior surface temperatures of the lighting fixture after 5 minutes operation is 45℃, when achieving steady state it is55℃.
There is no user serviceable parts inside the lighting fixture, do not open the housing and never operate the lighting fixture with the
covers removed.
If you have any questions, don’t hesitate to consult your dealer or manufacturer.

INSTALLTHE LIGHTING FIXTURE
When the lighting fixture is used, put it on a flat surface or hang it. Make sure it is steady and secured.
When the lighting fixture is used at a high place, as the figure above, move the support to the top of the lighting fixture, connect a lamp
hook to the mounting hole reserved in the support by screws, and then hang the hook to mounting bar. Eventually, use the safety cord
provided to pass through the support and hang it as a second safety fixing.

Connection between the controller and a lighting fixture and between one lighting fixture and another must be made with a 2
core-screened cable, with each core having at least a 0.5mm diameter. Please use the lighting fixture’s cannon 3- pin signal input and
output cables as connection. The 3-pin signal connections are connected as shown in the figure above.

5/14
Note: Care should be taken to ensure that none of the pins touch the metallic body of the plug or each other. The body of the plug is not
connected in any way. The device accepts digital control signals in protocol DMX512 (1990).
Maximum 32 units can be connected in series by 3-pin signal cable. Connect the controller’s output to the first fixture’s input, and
connect the first fixture’s output to the second fixture’s input and connect the rest fixtures in the same way. Eventually connect the last
fixture’s output to a DMX terminator as shown in the figure below.
Note: For synchronous control, StartAddresses for all slave units must be same.
Each unit’s POWER INPUT should be connected to external POWER individually and the voltage and frequency of the power
supplied match what its nameplate describes.
.DMX TERMINATOR
In the Controller mode, at the last fixture in the chain, the DMX output has to be connected with a DMX terminator. This prevents
electrical noise from disturbing and corrupting the DMX control signals.
The DMX terminator is simply an XLR connector with a 120Ω(ohm) resistor connected across pins 2 and 3, which is then plugged
into the output socket on the last projector in the chain. The connections are illustrated below.
