Instructions / Assembly

Congratulations and Introduction
Thank you for purchasing the FilterLinc Plug-In Noise Filter. The FilterLinc is designed to:
1. Prevent noisy electrical devices from polluting onto the power lines.
2. Prevent PLC/X10 signals from being absorbed into appliances.
Electrical noise on the powerline generally includes spikes, clutter, waveform disturbances, and
sags. Sometimes the noise will not affect the home automation system. But the frequency
may be close to that of the PLC/X10 signals. The noise makes it difficult for receivers to differ-
entiate between the PLC/X10 signal and background noise. Some receivers may have special
circuitry to help them detect the signals when noise is on the line, but even these modules
may benefit from the presence of a filter on a noisy device.
Signal attenuation by electrical devices is a more common source of problems for PLC/X10
products. Some electrical devices, when they are plugged in (and not necessarily turned on),
may absorb PLC/X10 signals. Using a FilterLinc between these devices will prevent the signals
from being lost. Read more about this and electrical noise problems in the section below.
Key Features
• 2-stage modified pie filter centered at 120 kHz
• 49.4 dB attenuation at 120 kHz
• Safety tested and approved by ETL
• Rated for up to 10 Amps (model #1626-10) or 5 Amps (#1626)
• Feed-through unfiltered outlet on the front for PLC/X10 receivers or transmitters
• Does not effect higher frequencies on the AC line like FM Intercoms and HomePNA devices
How to use
FilterLinc is installed between the offending device (noise maker or signal sucking appliance)
and the home’s AC outlet. Follow these steps to install your FilterLinc:
1. Turn off the device to be filtered (i.e. TV or computer).
2. Unplug the electricity cord from the receptacle.
3. Plug the cord into the FilterLinc Module's bottom "Filtered" outlet.
4. Optional: Plug a PLC/X10 transmitter, receiver, or another device that doesn't harm
PLC/X10 signals into the front "Always On" socket.
5. Plug the FilterLinc into the wall receptacle.
Now, the device that was causing PLC/X10 reliability problems will be isolated from the AC
lines and your home's automation system will be more reliable.
About Electrical Noise and Attenuation
Electrical Noise
These devices may emit electrical noise only when operating, so they can be difficult to detect.
Some of the common noise producers are:
• HID lighting
• Motorized devices (refrigerator, pumps, electric razors, hair dryers)
• Transformer-based lighting that use solid-state transformers
• Fluorescent-based lighting and ballast transformers
• Failed or failing X10 transmitters
In most cases, this problem may have resulted from an electrical device that you have recently
plugged in or an existing device if you are just starting with X10. There may be a device in the
home that is beginning to fail or is wearing out and it is putting noise on the line.
