IMPORTANT NOTICE
This installation guide provides basic guidelines for Rosemount® 752 Remote Indicator. It does not
provide instructions for configuration, diagnostics, maintenance, service, troubleshooting,
Explosion-proof, Flameproof, or intrinsically safe (I.S.) installations. Refer to the Rosemount 752
reference manual (document number 00809-0100-4377) for more instruction. This manual is also
available electronically on www.rosemount.com.
WARNING
Explosions could result in death or serious injury:
Installation of this indicator in an explosive environment must be in accordance with the appropriate
local, national, and international standards, codes, and practices. Please review the approvals section
of the Rosemount 752 reference manual for any restrictions associated with a safe installation.
• Before connecting a Fieldbus-based communicator in an explosive atmosphere, make sure the
instruments in the loop are installed in accordance with intrinsically safe or non-incendive field
wiring practices.
• In an Explosion-proof/Flameproof installation, do not remove the indicator cover when power is
applied to the unit.
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.

STEP 1: WIRING CONNECTION
Wiring for FOUNDATION fieldbus protocol
1. Remove the housing cover on terminal compartment side. Do not remove the cover in
explosive atmospheres when the circuit is live. Signal wiring supplies all power to the
indicator.
2. Connect the power leads to the terminals marked “FIELDBUS WIRING” as shown in
Figure 1. The power terminals are not polarity sensitive.
3. Plug and seal unused conduit connections on the indicator housing to avoid moisture
accumulation in the terminal side. If you do not seal unused connections, mount the
indicator with the electrical housing positioned downward for drainage. Install wiring with
a drip loop. Arrange the drip loop so the bottom is lower than the conduit connections
and the indicator housing.
NOTE
Do not apply high voltage (e.g. ac line voltage) to the indicator terminals. Abnormally high
voltage can damage the unit. (Indicator poser terminals are rated to 32 Vdc.
Figure 1. Fieldbus terminal block
Electrical Considerations
Proper electrical installation is necessary to prevent errors due to improper grounding and
electrical noise. Shielded, twisted pair cable should be used for best results in electrically
noisy environments. Cable Type A is recommended by FOUNDATION fieldbus.
Power Supply
The indicator requires between 9 and 32 Vdc (9 and 15 V dc for FISCO) to operate and
provide complete functionality. The dc power supply should provide power with less than 2%
ripple.
Power Conditioner
A fieldbus segment requires a power conditioner to isolate the power supply, filter, and
decouple the segment from other segments attached to the same power supply.
Grounding
Signal wiring of the fieldbus segment can not be grounded. Grounding out one of the signal
wires will shut down the entire fieldbus segment.
Shield Wire Ground
To protect the fieldbus segment from noise, grounding techniques for shield wire usually
require a single grounding point for shield wire to avoid creating a ground loop. The ground
point is typically at the power supply.
See Safety Messages page 2 for complete warning information.

Surges/Transients
The indicator will withstand electrical transients of the energy level usually encountered in
static discharges or induced switching transients. However, high-energy transients, such as
those induced in wiring from nearby lightning strikes, can damage the indicator.
Optional Transient Protection Terminal Block
The transient protection terminal block can be ordered as an installed option (Option Code
T1 in the indicator model number) or as a spare part. The spare part number is
03151-4131-0002. The lightning bolt symbol shown identifies it as a transient protection
terminal block.
NOTE
The fieldbus physical layer specification requires indicator communication during extreme
operating conditions of 250 V rms common mode signal. The transient terminal block was
designed to limit common mode voltages to 90 V and cannot be used in these extreme
operating conditions.
Grounding the Indicator Case
Always ground the indicator case in accordance with national and local electrical codes. The
most effective indicator case grounding method is a direct connection to earth ground with
minimal impedance. Methods for grounding the indicator case include:
•Internal Ground Connection: The Internal Ground Connection screw is inside the
terminal side of the electronics housing. The screw is identified by a ground symbol
( ), and is standard on the 752 Remote Indicators.
•External Ground Assembly: Ground screw is located at the bottom of the mounting
bracket.
NOTE
Grounding the indicator case using the threaded conduit connection may not provide a
sufficient ground. The transient protection terminal block (Option Code T1) will not provide
transient protection unless the indicator case is properly grounded. Use the above
guidelines to ground the indicator case. Do not run transient protection ground wire with
signal wiring; the ground wire may carry excessive current if a lightning strike occurs.

STEP 2: CONFIGURE THE TRANSDUCER BLOCK
The LCD Transducer Block can be configured to sequence eight different process variables.
If a function block is scheduled in the Rosemount 752 that links a process variable
from another device on the segment, that process variable can be displayed on the
LCD.
To configure the 752 Fieldbus Indicator use any FOUNDATION fieldbus configuration tool to
modify the configuration parameters for each value that is to be displayed.
DISPLAY_PARAM_SEL
The DISPLAY_PARAM_SEL parameter specifies how many process variables will be
displayed. Select up to eight display parameters.
BLK_TAG_#(1)
Enter the Block Tag of the function block that contains the parameter to be displayed. The
default function block tags from the factory are:
PID_1200
ISEL_1300
CHAR_1400
ARITH_1500
INTEG_1600
BLK_TYPE_#(1)
Enter the Block Type of the function block that contains the parameter to be displayed. (e.g.
ISEL PID, etc.)
PARAM_INDEX_#(1)
Choose the parameter to be displayed.
CUSTOM_TAG_#(1)
The CUSTOM_TAG_# is an optional user-specified tag identifier that can be configured to
be displayed with the parameter in place of the block tag. Enter a tag of up to five characters.
UNITS_TYPE_#(1)
The UNITS_TYPE_# parameter is generally selected via a drop-down menu with three
options: AUTO, CUSTOM, or NONE. Select CUSTOM and be sure to configure the
CUSTOM_UNITS_# parameter. Select NONE if the parameter is to be displayed without
associated units.
CUSTOM_UNITS_#(1)
Specify custom units to be displayed with the parameter. Enter up to six characters. To
display Custom Units the UNITS_TYPE_# must be set to CUSTOM.
(1) _# represents the specified parameter number.
