ç WARNING: Tank filters may suppress desirable communications carried on power lines in the 150 to 250 KHz
region. The filters may suppress carrier current such as that used for infant monitors and medical alert systems. Verify
that suppressed carrier current or other desirable communications on power lines creates no hazard to people or
property. Failure to observe this warning could result in damage to property, and or injury to death for personnel.
ç WARNING: All filter installation and wiring must be performed by qualified personnel and conform to local and
national electrical codes.
In-line power filters have been shown to properly suppress EMI; however, these filters must be rated for the entire load
current and are generally more expensive than the tank filter specified. An In-line filter may be required if carrier current
communications are used on site.
