Safety Instructions
- Disconnect power before installing, adding or changing any component.
- To avoid a hazard to children, account for all parts and destroy all packing materials.
- Do not install any luminaire assembly closer than 6” from any combustible materials.
- Positive (+) outputs require a fuse if the attached wire leads are not rated to handle the max current.
1. INSTALL : Determine the installation location for your controller. Make sure to consider the size of the controller (4.8” L x 2.9” W x 1.2” H) when determining your location. Note, it will require room for access and for wiring. Screw the controller in place using the four 5x15mm stainless steel Phillips pan head screws provided.
2. WIRING DIAGRAM: Follow the wiring diagram below to wire the module to your system.
*All unused zone(+) outputs must be isolated and secured so that they don’t touch anything. When power is applied to the controller they are life.
3. OPERATION: You are now ready to customize your lighting. Follow the operating instructions below or scan the QR code to watch a short video.

Installation Considerations for Preventing EMI Noise
WHAT IS EMI NOISE?
Electromagnetic interference (EMI) is any unwanted signal which is either
radiated(thru air) or conducted(thru wires) to electronic equipment and
interferes with the proper operation and performance of the equipment.
All electrical/electronic components that have varying or switching currents,
such as RGB lighting, create Electromagnetic interference (EMI noise). It is a
matter of how much EMI noise they produce. These same components are also
susceptible to EMI, especially radios and audio amplifiers. The unwanted
audible noise that is sometimes heard on a stereo system is EMI.
DIAGNOSING EMI NOISE
If EMI is observed the following steps should help isolate the problem.
- Turn off LED light(s)/controller(s)
- Tune the VHF radio to a quiet channel (Ch 13)
- Adjust the radio’s squelch control until the radio outputs audio noise
- Re-adjust the VHF radio’s squelch control until the audio noise is quiet
- Turn on the LED light(s)/controller(s) – If the radio now outputs audio noise then the LED lights may have caused the interference.
- If the radio does not output radio noise then the problem is with another part of the electrical system.
PREVENTING EMI NOISE
Once the EMI noise is isolated the following steps can be used to help prevent
and lessen the effect of the noise.
CONDUCTED & RADIATED SOLUTIONS
GROUNDING (BONDING) : How each component is connected and routed to the
power ground is important. Route the ground of sensitive components back to
the battery separately. Eliminate ground loops.
SEPARATION: Physically separate and mount the noisy components away from
sensitive components. In the wire harness, separate the sensitive wires from
the noisy wires.
FILTERING: Add filtering to either the device creating the noise or the
sensitive device. Filtering may consist of power line filters, common-mode
filters, ferrite clamps, capacitors and inductors.
RADIATED SOLUTIONS
SHIELDING :
Shielded cables can be used. Shielding the component in a metal enclosure is
also an option. If you continue to experience EMI issues please contact your
ITC sales representative.
