Introduction 1-7

The 8000-FHK/FST-IM Monitor Assembly common line is
connected to the metal enclosure. Therefore, when it is
powered by the “External Power and Communications Unit”
(ExPAC), the Monitor Assembly shall be bonded to the ExPAC
earth with a conductor having a minimum cross-sectional area
of 4 mm
2
, to achieve a resistance ≤1 Ω.
Other Conditions for Safe Use

The ADS Model 8000-FST-IM shall use only the 12-volt IS
Battery Pack (ADS p/n 8000-0043) for internal power.

Only ADS-approved sensors shall be connected to the ADS
Model 8000-FST-IM: ADS sensor types 8K-CS4 and 8K-CS5.

The only communication devices that may be connected to the
COMM + EXT PWR connector on the are the
USB Serial Interface (ADS p/n 8000-0337), the
ExPAC/XBUS/XIO power cable (ADS p/n 8000-378-10/25),
the Direct Connect Interface (ADS p/n 8000-0054), and the
Sampler Cable (ADS p/n 8000-0348).
Note:
The Triton-Telog Comm Cable (ADS p/n 8000-
0054-01) also may be connected to the COMM + EXT
PWR connector on the to provide
communication between the Telog Ru-33 and the monitor.
However, because the Ru-33 is not certified for IS
operation, an installation involving a connection between
these units will not be considered intrinsically safe, unless
the Telog unit is installed outside the hazardous area.
