AF300 Installation Instructions

TEST FOR SIGNAL STRENGTH AND NOISE...
using the AR300 and AT300. It is necessary to test the installation in the actual operating
environment. The amount and types of line loads may reduce the strength of the transmitted signal
and/or electrical noise may cause interference with the transmitted signal. Proper installation may
require additional couplers, filters or repeaters. Special coupling devices are required to allow signal
to be distributed to all phases and zero-crossings in multi-phase and multi-transformer distributions.
IF YOU HAVE ANY QUESTIONS...
Consult your nearest Engineered System Center (ESC) for additional information.
There are no field repairable assemblies on this unit. It is covered by a two year limited warranty.
If service is needed, the unit must be returned to the ESC where purchased. Contact your ESC for
return details.
INSTALLATION
CAUTION! Make all connections with the POWER OFF to avoid injury to the installer or damage
to the device.
1. Strip 3/4" of insulation from the ends of the AF300 conductors.
2. Make wiring connections as shown in Wiring Diagram. Check wiring connections to be sure they
are tight and no bare conductors are exposed.
3. Make sure the load or installation does not exceed the device rating.
4. Mount the AF300 in a standard 3-gang wall box.
CHECKOUT
1. Restore the power.
2. Check for proper signal filtering.
The AF300 is designed to filter out most signals above a frequency of 300 hertz by attenuating
or reducing the input voltage of these signals by a ratio of 40 to 1 (97.5%). You will need an
oscilloscope to properly test the AF300, but you can use the AR300 test receiver for a limited
noise test. The AR300 has an “Error Condition” LED (Yellow) that indicates excessive noise.
To test the AF300, plug or clip the leads of the AR300 between the red and white leads of the
AF300. The AF300 should remove the noise that causes the error condition.
