3. Installation
3.1 Fitting/Exchanging the lamp
DANGER!
Install the lamp with the fixture switched off.
Unplug from power supply before opening unit!
To insert the lamp, open the top cover of the head (see the drawings to identify
which cover is top) by loosening the 4 Phillips screws on the front and rear sides
of the top cover. Then open the small lamp cover by loosening the 3 thumb
screws (see the drawing). If changing the lamp,
remove the old lamp from the socket and insert
the new lamp. Do not install a lamp with a higher
wattage as it may generate temperatures the fix-
ture was not designed for. Damages caused by
non-observance are not covered by warranty.
Please follow the lamp manufacturer‘s notes! Do
not touch the glass-bulb barehanded during the
installation! Make sure that the lamp is installed
tightly into the lamp holder system. Adjust the opti-
mal distance 1-1.5 mm from the lens by turning
the screw "A" (see the drawings "Lamp adjust-
ment" next page). Then close the small lamp
cover by tightening the 3 thumb screws. Close the
top cover of the head and tighten the 4 Phillips
screws. Before striking the lamp, reset the "LAti"
counter in the main menu of the Control Board, by
pressing the "Up" and "Down" buttons in one
time and then confirming with the [Enter] button.

ENGLISH
Do not operate the fixture with housing cover open!
Lamp Adjustment
The ARENA PROFILE SPOT lamp holder is aligned at the factory. Due to differ-
ences between lamps, fine adjustment may improve light output.
Strike the lamp and focus the light on a flat surface (wall). As the optimum distance
of lamp from lens was adjusted during the installation of the lamp (by turning the
screw "A"), it should only be necessary to adjust only the second position by turning
the screw "B", in order to center the hot-spot (the brightest part of the beam). If the
Hot Spot seems to be too bright, you can lower its intensity by moving the lamp
closer to the reflector. Do so by turning screw "A" until the light is evenly distributed.
If the light on the edge seems to be brighter than the center, the lamp is too close to
the reflector. In this case, you need to move the lamp away from the reflector until
the light is evenly distributed and the beam appears appropriately bright.

3.2 Installation of an optional lens
The fixture is delivered with a 15° standard lens. If you wish to insert an optional
12° or 18° lens, please follow the instructions below:
Optional 12° lens:
Remove the C-Clip of the 15° lens with an appropriate tool. Remove the lens.
Install the optional 12° lens and secure it with the C-Clip.
Optional 18° lens:

3.4 Rigging the fixture
DANGER OF FIRE!
When installing the fixture, make sure
there are no highly flammable Materials
(decoration articles, etc.) closer than 0.5 m.
CAUTION!
Use 2 appropriate clamps to rig the fixture to the truss.
Follow the instructions on the bottom of the base.
Make sure that the device is secured properly! .
The ARENA PROFILE SPOT can be
placed directly on the stage floor or rigged
in any orientation on a truss without altering
its operational characteristics (see the
drawing). The fixture’s base enables it to be
mounted in two ways. Use the clamps with
either M10 or M8 screws -check the base
bottom. Install a safety-cable that can hold
at least 10 times the weight of the fixture.
Never use the carrying handles for secon-
dary support.

ENGLISH
3.5 Connection to the power supply
Connect the fixture to the power supply with the plug.
The earth has to be connected!
The configuration of the power supply cables is as follows:

16
Configuration of the XLR connector:
Building a serial DMX chain:
Connect the DMX output of the first fixture in the DMX chain with the DMX input
of the next fixture. Always connect one output with the input of the next fixture
until all fixtures are connected.
Caution:
At the last fixture, the DMX cable has to be terminated with a DMX terminator.
Solder a 120 Ω resistor between Signal (–) and Signal (+) into a 3-pin XLR plug
and plug it in the DMX output of the last fixture.
3.7 DMX-512 connection between fixtures and controller
Individual bare DMX Control wires must not come into contact with
each other, otherwise the fixtures will not work properly or at all.
Only use a stereo shielded cable and 3-pin XLR plugs and connectors in order
to connect the controller with the fixture and one fixture with another.
