5-2 ADS Manual
Installation
A typical field installation involving external power requires 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

An earth ground rod installed next to the pole/post bonded to
the AC distribution device

An AC to 24-volt DC converter (i.e., power supply). ADS
recommends a power supply available through ADS (p/n
508293), which works with worldwide AC power (94 – 240
VAC, 50 – 60 Hz). This power supply is provided
automatically as part of the XIO and XBUS, but must be
ordered for the ExPAC, when a power supply is required.
However, please note that the customer may use another AC-to-
DC converter/power supply, if desired, to support the ExPAC,
provided it can supply from 9 to 36 volts of power at a
minimum of 15 watts.

A power cable running between the external DC source (i.e.,
power supply) and the ExPAC power input. The customer
must supply this cabling of the appropriate length and
specifications

A properly rated enclosure to house and protect the ExPAC and
power supply
Note:
Applications involving an XIO or XBUS do not
require an additional power cable or an enclosure because
they are included. The power is pre-run between the
power supply and ExPAC inside the XIO enclosure.

A communication cable (ADS p/n 8000-0378-xx, where xx
represents the required length of the cable ) running between
the ExPAC/XBUS/XIO and the monitor
