Complete the Installation
After the installation is complete, perform the following tasks:
1. Inspect the connection of the ECN to the Pole Mounting Bracket.
2. Inspect the connection of the Pole Mounting Bracket to the utility pole.
3. Inspect the cabling connections to the ECN.
The completed installation should look similar to the views depicted in Figure
13 on page 31. Note that the figure does not show the cabling connections to the
ECN.
Verifying Successful Installation
Because the ECN has no external lights or displays, it uses an internal audio
buzzer to provide indications of important installation-related states. The
buzzer’s audio frequency is 2.4 kHz (as a 1/2 duty cycle square wave) and outputs
85 to 92 dBA of sound pressure,

which should be audible from at least 10 m (30
ft). Table 3 on page 34 lists the sound patterns for the audio indicator. The
audio indicator outputs its audio indicator patterns only during ECN startup.

dBA measures sound pressure levels relative to 20 µPa (rms) at 1 m.
