5-2 IETG FlowHawk Manual
Installation
A typical installation involving external power includes the
following:
 An AC mains 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, or breaker
box) on the pole/post
 A ground rod installed next to the pole/post bonded to the AC
distribution device
 An AC to 12-volt DC converter (IETG recommends using the
IETG-supplied power supply (p/n 5000-0727), which works
with worldwide AC power (94 – 240 VAC, 50 – 60 Hz))
 A cable running between the external DC source and the EMU
or EMUX. The External Power Kit (p/n 3800-0181) designed
for use with the EMU includes this cable. However, the
customer must supply cabling of the appropriate length and
specifications for the EMUX. The DC power supplied must be
regulated 12 V +/-10%.
Note: All work required to run AC power to the pole and
wire the power into an approved AC distribution device
(i.e., a disconnect, fuse, or breaker) should be performed
by a licensed electrician. Typically, an electrical permit
from the owner of the collection system or local power
authority is required to install a pole or electrical
equipment next to a monitor location.
