SAFE USAGE OF THE PROJECTOR
When unpacking and before disposing of the carton, check there is no transportation damage before using the projector.
Should there be any damage caused by transportation, consult your dealer and do not use the apparatus.
The projector can be used indoors and outdoors, IP67.
The projector is not designed or intended to be mounted directly on to inflammable surfaces.
The projector 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 light from the lamp. The light is harmful to eyes.
Do not attempt to dismantle and/or modify the projector in any way.
Electrical connection must only be carried out by qualified personnel.
Before installation, ensure that the voltage and frequency of power supply match the power requirements of the projector.
It is essential that each projector is correctly earthed and that electrical installation conforms to all relevant standards.
Do not connect this device to any other types of dimmer apparatus.
When the projector is hanged to a high place, please use a safety cord provided to pass through as a secondary safety
fixing for safety reasons. For details, refer to “INSTALLTHE PROJECTOR “section.
Make sure that the power-cord is never crimped or damaged by sharp edges. Never let the power-cordcomeintocontact
withothercables.Only handle the power-cord by the plug. Never pull out the plug by tugging the power-cord.
LED lens shall be changed if they have become visibly damaged to such an extent that their effectiveness is impaired, for
example by cracks or deep scratches.
Exterior surface temperatures of the projector after 5 minutes operation is 55℃, when achieving steady state it is 70℃.
There is no user serviceable parts inside the projector, do not open the housing and never operate the projector with the
covers removed.
Always disconnect from the mains, when the device is not in use or before cleaning it or
before attempting any maintenance work !
If you have any questions, don’t hesitate to consult your dealer or manufacturer.

INSTALLTHE PROJECTOR
Take 2 clamps and safety cord out from the package and mount 2 clamps on the underside of fixture with 2 retainers
attached to each clamp. Hang the fixture on the structure and fasten the screws attached to each clamp. Always ensure
that the projector is firmly anchored to avoid vibration and slipping whilst functioning. Always ensure that the structure that
you are going to mount the projector is secure and is strong enough to support a weight of PR-8800.
WARNING:
1. The projector MUST be lifted or carried by the HANDLES instead of clamps.
2. For safety the safety cord should afford 10 times of the unit’s weight.
CONTROL SYSTEMAND POWER CONNECTION
Connection between the controller and a projector and between one projector and another must be made with a 2
core-screened cable, with each core having at least a 0.5mm diameter. Please use the projector’s cannon 3- pin signal
input and output cables as connection. The 3-pin signal connections are connected as shown in the figure above.
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 fixture accepts digital control signals in protocol DMX512 (1990).
The amount of projectors connected in parallel is not more than 32. Connect the controller’s output to the first fixture’s
input cable with a 3-pin signal cable, connect the first fixture’s output cable to the second fixture’s input cable and connect
the rest fixtures in the same way. Eventually, connect the last fixture’s output cable to a DMX terminator. Note: Only when
all the start addresses of fixtures are set the same, synchronous control could be achieved.
When the first fixture is not connected to the controller, and all the other connections are the same as above, it is master /
slave mode connection. To achieve master / slave mode, set the first fixture master, the others salve( slave is default).
As for power connections, each projector has to be supplied separately by external power. Use the power cord of each
projector to connect the mains power directly, paying attention to the voltage and frequency marked on the panel of the
projector.

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.
