External Power 5-3

A 10-gauge (4 mm
2
) earth ground wire (included in external
power grounding kit, ADS p/n 8000-0434-xx, where xx
represents the required length of the wire ) running between the
ExPAC/XBUS/XIO and the monitor.
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.
DC Power Requirements and Consumption
To run on external power, the system requires a power
source capable of supplying between 9 and 36 volts and a minimum
of 15 watts as measured/available at the ExPAC (not at the power
source output). ADS offers a power supply (ADS p/n 508293) for
this application. However, if you choose not to use this
recommended power supply, the alternate power supply must be a
high-quality industrial-type power supply with ripple no greater
than 250mV P-P. When long cable runs are required, size the
supply and cabling to ensure that line losses do not reduce the net
power available to the ExPAC.
To support monitors running in continuous mode, the
external DC power source must be capable of accommodating the
following system requirements concerning power consumption:
Note:
The power to the monitor is ATEX/IECEx I.S.
compliant at 8 to 11.8 VDC.
Following are the power requirements for monitors that
communicate wirelessly and obtain power through an ExPAC:

Monitor in Sleep Mode with Modem Power On
26 mA

Monitor in Sleep Mode with Modem Power Off
25 mA
