PRODUCT
OVERVIEW
AND
PRECAUTIONS
The 375 Field Communicator, when labeled, is an
industrial handheld communicator approved for use in
hazardous locations classified as Zone 0 (FM and CSA
only), Zone 1, or Zone 2, Division 1 and Division 2. The
fieldbus segment, to which the 375 Field Communicator
is connected, is allowed to go through Zone 0, 1, 2 and
Zones 20, 21, 22, Division 1 and Division 2.
The 375 Field Communicator supports HART and
OUNDATION fieldbus devices, allowing the user to
F
configure or troubleshoot in the fiel d. Whe n usin g the
375 Field Communicator to communicate with devices,
all standards and procedures applicable to the location
should be followed. Failure to comply may result in
equipment damage and/or personal injury. Be sure to
understand and comply wi th the fol lowi ng item s :
• The portable 375 Field Communicator includes an FSTN
type LCD with touch-screen, an NiMH battery pack, an SH3
processor, memory components, and integral
communication and measurement circuitry.
• An IS-approved 375 Field Communicator can be used in
Zone 0 (FM and CSA only), Zone 1, or Zone 2, Division 1
and Division 2 locations (KL option only).
• An IS-approved 375 Field Communicator may be connected
to loops or segments that are attached to equipment located
in Zone 0, Zone 1, Zone 2, Zone 20, Zone 21, Zone 22,
Division 1 and Division 2 (KL option only).

• The touch screen must be contacted using blunt items only,
preferably the stylus provided by the factory. Using sharp
instruments, such as screwdrivers, can cause failure of the
touch-screen interface and void the warranty. Repair of the
touch screen requires replacement of the entire 375 Field
Communicator display assembly, which is possible only at an
authorized service center.
• There are three terminals on the top of the unit. Two are red
and one is black. Each red terminal is a positive connection
for its protocol, while the black terminal is a common terminal
shared by both protocols. An access door ensures only one
pair of terminals is exposed at any one time. Several
markings indicate which pair of terminals is for which
protocol.
• When connecting the 375 Field Communicator to an active
F
OUNDATION fieldbus segment, ensure there is adequate
spare current capacity to power the 375 fieldbus circuits. The
375 Field Communicator draws approximately 17 mA.
• The infrared port and card reader provide methods for the
375 Field Communicator to interface with a PC.
• Data is input into the 375 Field Communicator via the keypad
or touch-screen interface.
• An Expansion Module (EM) (labeled Expansion Module) is a
removable memory card that snaps into the Expansion Port.
Removal and installation of an EM is allowed in a hazardous
area.
• Only the Expansion Module or Expansion Port Plug should
be inserted into the Expansion Port. System Cards/Secure
Digital cards or other objects must not be put into the
Expansion Port. Failure to comply will void the IS approval
and the warranty.
• The Secure Digital cards used in the System Port must be
those supplied by the 375 Field Communicator manufacturer.
Failure to comply will void the IS approval and the warranty.
• Removal and installation of the battery pack in a hazardous
area is allowed.
• The battery pack must not be charged in hazardous area
environments.
• The battery pack may only be charged with the 375 Field
Communicator power supply/charger. Failure to comply may
permanently damage your 375 Field Communicator and will
void the IS approval and the warranty.
• The power supply/charger should be safeguarded from
moisture. Operating and storage temperature limits should
be respected.
• The power supply/charger should not be covered, subjected
to direct light, or placed upon or next to heat-sensitive
materials.
• Do not open or modify the power supply/charger. There are
no user-serviceable components or safety elements inside.
Opening or modifying the power supply/charger will nullify
the guarantee and the warranty.
• Use the power supply/charger with the 375 Field
Communicator only.
