1. Never locate the fixture on any flammable surface.
2. Minimum distance from flammable materials: 0,5 m.
3. Minimum distance from the closet illuminable surface: 0,5 m.
4. Replace any blown or damaged fuse only with those of identical
values. Refer to the schematic diagram if there is any doubt.
5. Connect the projector to mains power protected by a thermal mag-
netic circuit breaker.

1. Presence of high voltage inside of the fixture. Insulate the projector
from mains supply before opening or performing any function
which involves touching the inside of the fixture, including lamp
replacement.
2. For the connection to the mains, adhere strictly to the guidelines
outlined in this manual.


1. The projector must always be installed with bolts, clamps, or other
fixing devices which are suitably rated to support the weight of the
projector.
2. Always use a secondary safety fixing device with chain or steel wire
of a suitable rating to sustain the weight of the unit in case of failure
of the principal fixing point.
3. The external surfaces of the unit, at various points, may reach 60°C.
Never handle the unit until at least 10 minutes have elapsed since
the LED was turned off.
4. Never install the fixture in an enclosed area lacking sufficient air
flow; the room temperature must not exceed 40°C.
5. The projector contains electronic and electrical components which
must under no circumstances be in contact with water, oil or any
other liquid. Failure to do so will compromise the proper functioning
of the projector.

1. The fixture is under warranty for 24 months from the purchase date against
factory defections.
2. Damage ought to unskillfulness, inappropriate use, or lack of suggested
maintenance are excluded from the warranty.
3. Warranty expires when the projector is opened by unauthorized personnel.
4. Warranty doesn’t include the replacement of the fixture.
5. Serial number and model of the fixture are necessary to retrieve informations and
assistance from the dealer.
3. The level of technology of  EXT FullSpectrum RGBLA re-
quires the use of specialised personnel for all service applications;
refer all work to your authorised  service centre.
4. A good earth connection is essential for the proper functioning of
the projector. Never connect the fixture if there is no earth connec-
tion.
5. Mains cables must not come into contact with other cables.
6. Do not operate the projector with wet hands or in an area where
water is present.
7. The fixture must never be located in an exposed position, or in ar-
eas of extreme humidity.
2.3 
1. The fixture satisfies the essential requirements of the directive 2004/108/EC,
2006/95/EC, 2011/65/EC, 2002/96/EC & 2003/108/EC.

EXT FullSpectrum RGBLA may be hung from an appropriate structure in
any position or on tripode. If hanging the fixture from a lighting truss or similar, we
recommend the use of an appropriate clamp “A”, as shown in the following diagram.

Always ensure that your support
structure and fixing (bolts, clamps,
etc…) are rated to support the weight
of the fixture.
4.2 
When hanging EXT FullSpectrum RGBLA it is recommended to use a safety
chain, as required by current legislation. The safety chain must pass through the
handles of the unit and then attached to the structure.

re-tighten until the gobo is well fixed. At this point reinsert the dual gobo rotator
keeping it slightly inclined “N” so that it can enter in the optical group and fix it in the

The use of a thermal/magnetic circuit breaker is recommended. Strict adherence to regula-
tory norms is strongly recommended.
EXT FullSpectrum RGBLA should not be powered through a dimmer as this may
damage the internal switching power supply.
Prior to connecting the device to mains power, ensure that the mains characteristics are
within the recommended range for the use of EXT FullSpectrum RGBLA.
All cabling and connections should be carried out by a suitably qualified personnel.

 Protect all connections from moisture or water.
The moisture or the water can cause corrosion in unprotected cable connections.
They can also be along the inside of cables at breaks (for example at connection
points) and into fixtures because of the vacuum effect of temperature fluctuations
inside fixtures. To protect connections and fixtures from moisture or water, use the
Junction connectors that are protected to IP67 or higher.

suddenly it will show the current DMX addressing. If the address blinks, it means
that the DMX signal has not been received. Check the connection cable and the
