External Power 5-3
Typical Installation
A typical external power installation includes the following:
 Bringing a single phase, 120 volt AC power line terminated at a
pole or post close to the manhole (work done by others).
 Installing an AC disconnect/fuse box on the pole (work done by
others).
 Installing a ground rod installed next to the pole bonded to the
disconnect/fuse box (work done by others).
 Installing a box on the pole containing the AC to 12V DC
converter (refer to Installation of the ADS
® Power Supply on
page 5-4 for more information).
 Installing a cable (ADS p/n 5000-0697) connecting the DC
supply power to the monitor.
Note: All work necessary to run AC power to the pole
and wire it into an approved AC distribution device
(disconnect, fuse or breaker) should be done by a licensed
electrician. An electrical permit from the collection system
owner or power authority is typically required to place a
pole and electrical equipment next to the site.
DC Power Requirements
The monitor requires a power source capable of supplying 1.2
amperes of 12 volt regulated DC power (as measured/available at
the monitor, not as available at the power source output). If long
cable runs are used, the supply and cabling must be sized to ensure
that line losses do not reduce the net power available to the monitor.
