Unpacking
After receiving a package, carefully unpack the it, check the contents to ensure that all
parts are present, and have been received in good condition. Notify the shipper immediately and retain
packing material for inspection if any parts appear damaged from shipping or the carton it self shows
signs of mishandling. Save the carton and all packing materials.In the event that a fixture must be
returned to the factory, it is important that the fixture be returnedin the original factory box and
packing.
Power Before powering on the unit is to make sure the line voltage you are applying is within the
range of accepted voltages. This fixture will accommodate 3 phase 230V AC power connected in
phased bases L1+L2+L3+N+E. Fixture must be powered directly off a switched circuit and can not run
off a rheostat (variable resistor) or dimmer circuit, even if the rheostat or dimmer channel is used
solely for a 0% to 100% switch.

2. INTRODUCTION
Device description
The OMEGA, OMEGA+ and OMEGA W are a "Company NA" manufactured dimmers. The
Omega series dimmers are designed for controlling incandescent lamp brightness. The dimmers has
12 or 24 output channels. Its operating principle is based on triac ignition phase regulation.
The dimmer's output channel control is DMX-512 or manually from the front panel using the
“Test” or “Chase” modes. Operating the dimmer in “Test” mode, the output levels can be set with the
use of the graphic display independently of the DMX input. The “Test” mode allows for two output
signal set sizes –single channel (C) or group (G). Operating the dimmer in “Chase” mode replays a
prerecorded sequence independently of the DMX input. Six seperate sequences can run with control
of the sequence speed and direction, as well allowing the setting of backdrop levels. The settings
programmed in “Chase” mode operate only in this mode.
The OMEGA series dimmers front panel includes: display, operating controls, a digital
potentiometer, as well as 13 A or 16A circuit breakers for each individual regulated channel.
The OMEGA display graphically shows the DMX address set and input signal for 12
channels.

3. Setup
Installation Guide
These installation instructions is to explain the OMEGA system installation specifics.
However, this instruction is not a wiring regulation. Before the installation of the system need to
find a local state of wiring and installation options.
Installation instructions are divided into three parts:
- System Positioning specification,
- Installation guide,
- Appendix department, with other useful information.
Before the installation of the system read the first two chapters
Specification of system OMEGA dimmers
Setup
Dimmer OMEGA is designed for installation in the 19' rack or wallmount. Dimmer can be
installed on the stage or away from them, as well as for use in the touring. It is not advisable to
install the system in a public place where there is no possible access to the equipment without
disturbing the show. It is not advisable to place these devices close to the sound hardware.
Like any other dimmer, the OMEGA emit heat, so it must permit normal air circulation on
site. OMEGA system maximum operating temperature is +40 º C.
Power suply
OMEGA dimmer system must have 3 - Phase, 5 core supply the place of installation of the
following: 3 - Phase, 5 core phase to phase supply to the TN-S wiring system (connection
scheme L1 + L2 + L3 + N + E). Connection cable size depends on the dimmer fuse size
(cutting size) and it can be up to 35mm2 copper wire (see: the power cable characteristics).
Neutral cable should be large enough to lead the neutral current resulting from a phase shift as
a result of the dimmer is used part-intensity (typically up to 130% of the maximum possible
power phase). Strongly not recommended for smaller neutral cable, as it requires a dimmer
system for feeding.

Maximum fuse (switches) Dimensions:
Mono frame, with or without mains isolators
125A D-type auto fuse or equivalent (which
may be a fuse switch)
Double frame system without mains
isolators
250A D-type auto fuse or equivalent (which
may be a fuse switch)
Double frame system is equipped with
mains isolators
160A D-type auto fuse or equivalent (which
may be a fuse switch)
Power requirements
Wire size and load to the circuit wiring should comply with the rules. Dimmer fuse (switch)
size must comply with local cable overall dimensions (16A C-curve, or the 32A C-curve). If the
run size of one channel is up to 6mm2, the dimmer system is used to 16A C-curve fuse on one
channel, but if the run size is 10mm2, the system is used dimmers 32A C-curve fuse for each
channel.
Cooling
To provide cooling OMEGA and OMEGA + dimmers are equipped with two-high speed
internal fans, casing on the left side of unit corps. Fresh air is injected through holes in the left
side of corps, but warm air is discharged through holes located on the right side of corps.
Instalation
Preperation of the necessary components
Dimmer OMEGA is shipped with out a cable that is secured in place. In order to properly
carry out the installation of a dimmer prepare the section below details:
● Remove the wire connecting terminals by unscrewing two screws and at the same time
holding the DIN cable path. Then remove the wire connecting blocks.
● Disconnect the cable from the main arrivals cable connecting the frame (to move the cable to
the fuse side of 15mm, and move horizontally on 20mm)
● If the input cable is provided for detachable cable to the plate, remove it now.
Assembly of main cable
Mains power cable attach to a cable input terminal at the rear of the hull. The main power
cable assembly can be connected to a five-strand copper cable with conductor sizes up to
35mm2. To do so requires a straight blade screwdriver with a width of 4mm. Insert the screw-
blade main power cable assembly and press it. Now may be removed and a screwdriver with
both hands, insert the main power cable to connect the strands in the block hole. Make sure
the wires are placed correctly and outside the conductor connecting clamps are not visible
purified cable conductor parts.

Starting the system
Check incoming power cords
Check the incoming wires are connected properly and securely tightened,
Check whether the wires have the correct contact sockets.
Using a multimeter check the short circuit between phases, neutral and earth.
Check power cords
Make sure all cables are properly connected and isolated and complies with both ends of
the connection.
Make sure all ground wires are connected properly.
Using a multimeter check short circuit between phases, neutral and earth.
Turning on
Turn off all circuit breakers.
Turn on the main switch of sufficient capacity fuse.
Make sure the LED indicators show the proper interconnection.
Management screen, main menu appears with all the channels.
Channel output check
a) Push the menu button,
b) with [up]/[down] direction buttons find [Test], [enter] (with menu button),
c) 1st channle is blinking, roll encoder, 1st column rise a level up,
d) with [LEFT]/[RIGHT] direction buttons change the channels.
Unplug power before service.
Always use the same type of parts for service.
