5-2 ADS FlowShark IS Manual
Typical Installation
A typical external power installation includes the following:

A single-phase, 120-volt AC power line terminated at a pole
or post close to the manhole in which the monitor is installed.

An AC distribution device (i.e., disconnect, fuse box, or
breaker box on the pole/post.

A ground rod installed next to the pole/post bonded to the
distribution device.

An AC to 12V DC converter on the pole/post. ADS
recommends using an ADS Power Supply (p/n 5000-0727).

A cable (ADS p/n 5000-0697) connecting the external DC
power source to the EMU. ADS offers a 10-foot long, 0.25-
inch diameter external power cable (ADS p/n 5000-0697) with
an ethylene/propylene copolymer jacket.
Note:
All work necessary to run AC power to the pole
and wire into an approved AC distribution device (i.e.,
disconnect, fuse, or breaker) should be performed by a
licensed electrician. Typically, an electrical permit from
the collection system owner or power authority is required
to install a pole and/or electrical equipment next to a site.
DC Power Requirements
The IS FlowShark system requires a power source capable of
supplying a minimum of 1 ampere of 12-volt regulated DC power
(as measured/available at the EMU, not at the power source output).
For long cable runs, size the supply and cabling to ensure that line
losses do not reduce the net power available to the EMU. If the
application will not involve an ADS Power Supply (ADS p/n 5000-
0727), choose a high-quality industrial type power supply with
ripple no greater than 250mV P-P.
