1 OVERVIEW
This manual explains the installation and maintenance procedures for the
9189 Redundant Fieldbus Power Supplies and must be read in association with the
product datasheets that contain the electrical data.
The 9189 fieldbus power system is designed to provide redundant power for eight
Foundation™ fieldbus H1 segments. It is optimised for use in general purpose
and hazardous area High Energy Trunk architectures which, with the appropriate
FieldPlus™ wiring components, supports fieldbus devices using all hazardous area
protection techniques. The power supply has been designed to optimise cabinet
layouts, maximising the number of fieldbus segments powered per cabinet while
providing space for installing and maintaining cable connections and minimising the
operating temperature.
Various configurations are available by ordering the appropriate model number.

2 DESCRIPTION
The system provides segment current capacity in 250mA increments, up to 500mA,
and then offers redundancy with the provision of an additional 250mA module, which
is connected in a load-sharing manner, to achieve an N+1 type of configuration.
Each 919x-FP module will support 4 segments, so two “groups” of modules are
required to support 8-segments. The following diagram explains the options when
chosing current capacity and/or redundancy for an 8-segment system.

(* A blanking module is recommended for each unused position- see Section 5.9 on page 11)
Figure 2.1- Application options
Diagrams b) and c) are the same in their implementation but differ in their function
because, while b) can offer 500mA per segment, c) is designed to guarantee 250mA
per segment even if one of its power modules should fail.
So, for redundant applications, initially requiring up to 250mA current per segment,
two groups of two 919x-FP modules are fitted on the carrier (diagram c), with the
option of adding a third power module to each group (diagram d) in the event of future
segment expansion.
NOTE
To avoid incompatible output voltages within each block of redundant modules, 9191-
FP and 9192-FP module types should not be mixed on a 9188-CA-Px module carrier.
2.1 Load sharing and output redundancy
Each module is designed to supply four output segments, and any additional modules,
up to a total of three, operate on a true load-sharing basis, where the current supplied
by a module is balanced with that supplied by the other(s).
The module indicated by ‘+1’ in Figure 2.1 is identical to the others, but the ‘+1’
indicates its role of ‘redundancy’, and that it can maintain power to the segments in
the event of a module failure.
2.2 Input power redundancy
Redundancy is also available in the supply of power to the modules. Power A and
Power B terminals enable two independent supplies to be connected to the carrier
and their power is distributed to the three module positions as indicated in Figure 2.3.
Module ‘A’ is supplied by Power A, module ‘B’ is supplied by Power B and module ‘C’
is powered by diode ‘OR’-ing Power A and B. This ensures that output is maintained if
one of the Power inputs should fail or be interrupted.

2.3 Alarms
Each 919x-FP module monitors the output of the four fieldbus segments and indicates
an alarm (by means of a built-in, normally-closed relay) if any of the segments is
shorted, or its output falls below the ‘minimum output voltage threshold’. Failure of
either of the two bulk power input supplies is also announced.
The alarm contacts are volt-free and galvanically isolated from other circuitry.
Connections to the alarm relays are made via terminals on the 9189-CA-Px carrier; a
separate alarm module is not required for this function, but see Section 5.9 on page
11 for guidance when power modules are removed from the carrier.
LED indicators show the status of each 919x-FP module and that of the four individual
segments. In normal operation each segment LED is lit, showing that the segment is
powered. If a segment is shorted, this LED is extinguished, and the module Alarm LED
is lit. See Section 5.9 on page 11 for connection details.
2.4 Isolation
The 919x-FP module provides galvanic isolation between the 24V DC input power
and the fieldbus segments, as required by the IEC61158-2 fieldbus standard and
the Fieldbus Foundation™ FF-831 validation test for power conditioners. There is
also galvanic isolation between the fieldbus segments, thereby preventing multiple
segment failures due to ground faults on more than one segment.
2.5 Physical layer diagnostics
A separate physical layer diagnostics module - F809F-Plus - may be installed on the
carrier to automatically collect and distribute additional diagnostic information for each
of the eight fieldbus segments. For more in-depth information see the F809F-Plus
product specification and its instruction manual (INM F809F-Plus).
2.6 Surge protection
Pluggable surge-protection components for each fieldbus trunk are available as an
option reducing the installed cost of providing surge protection on fieldbus networks.
2.7 Connector options
The carrier provides fixed, 3-way, screw-terminal connections for the host/system, the
diagnostic segment and the grounding wiring.

5
INM9189 Rev 4
The input power, field segment and alarm wiring connections are available with the
option of either pluggable screw terminals (9189-CA-PS) or pluggable spring-clamp
terminals (9189-CA-PC). The pluggable connections are screw-retained providing a
reliable connection in an industrial environment.

4 MECHANICAL
4.1 Mounting Orientation
The optimum orientation for the 9189-CA-P* carrier is mounted on a vertical surface
using a horizontally aligned DIN-rail, or surface mounted in the same orientation- see
Figure 4.1. This method of mounting ensures optimum heat dissipation from the 919x-
FP Power Supply Modules, and an operating temperature range of –20°C to +60°C. If
the DIN rail is mounted vertically on a vertical surface then the upper temperature limit
must be reduced to +50°C.
Plus
Figure 4.1 - Preferred mounting orientation
4.2 Enclosure Requirements
4.2.1 General Requirements
The assembly may be mounted in Hazardous (classified) areas – see Sections 8. The
following conditions must also be satisfied to ensure safe and reliable operation.
a) The equipment must be installed in an area of not more than pollution degree 2 as
defined in IEC 60664-1 and in an enclosure that provides a degree of protection of at
least IP54 and meets the relevant requirements of IEC 60079-0 and IEC 60079-15.
b) Prevent any form of pollution that could compromise the operation of the unit. For
example, choose an unpolluted location or a suitable enclosure to protect the assembly.
c) Provide an adequate level of mechanical protection.This can be achieved by selecting
a protected location, a suitable enclosure, or a combination of both.
d) Ensure that all cable entries and connections are secure by making provision for the
careful routing and securing of all cables.
e) Provide adequate security against unauthorized interference.
f) Ensure that the permitted ambient temperature range detailed in Section 4.1 is not
exceeded. Allow for power dissipation within the enclosure and consider the use of
shading against direct sunlight.
4.2.2 Outdoor Mounting
If the power system is mounted in an outdoor location, use a suitable enclosure with
a minimum of IP54 ingress protection. A higher level of ingress protection rating will
be necessary if the working atmosphere is or can be corrosive or if the enclosure is
subject to wet or dusty environments.
All fixing bolts must be suitable for the mounting surface and the environmental
conditions. Prepare holes in the mounting surface, on the centres shown in Figure 3.1
or 3.2, to accept suitable screws/bolts for mounting.

7
INM9189 Rev 4
4.3 DIN-rail mounting option
The carrier is designed for mounting on 35mm x 7.5mm T-section “top hat” DIN rail to
EN50022 and uses four built-in DIN clamp tabs to hold it on the rail.
4.3.1 To mount on DIN rail
The power modules at each end of the carrier must be removed to obtain access to
the DIN-rail clamp screws.
Before starting to mount the carrier on the DIN rail, insert a small screwdriver through
the access holes in the circuit board (Figure 4.2) and rotate all four of the clamping
screws counterclockwise (i.e. unscrew) until the clamping tabs have been swung out
of the channel for the DIN rail- as position ‘A’ in Figure 4.3.
Figure 4.2 - Carrier top showing an
access hole and rotation directions for
the locking tabs.
Figure 4.3 - Carrier underside showing
tab open position (A) and closed position
(B)
Press the carrier onto the DIN-rail and rotate each of the clamping screws clockwise
until each of the four tabs is tightened against the DIN-rail- as position ‘B’ in Figure 4.3.
(Recommended torque: 0.5Nm)
4.3.2 Removal from DIN rail
The power modules at each end of the carrier must be removed to obtain access to
the DIN-rail clamp screws.
Support the carrier by pressing it to the DIN-rail and unscrew (counterclockwise) the
four indicated DIN-rail clamping screws.
NOTE
Turn each screw no more than three full turns when releasing its clamping tab from
the rail. Further turns should be unnecessary and could ultimately damage the
circuit board or the carrier.
Remove the carrier.
4.4 Surface mounting
The rear face of the carrier has four circular raised feet with slotted holes for mounting
the carrier onto a flat surface. See Figure 4.3.

8
INM9189 Rev 4
NOTE
The carrier hangs on the fixings and so there must be a minimum of 10mm
top clearance above the carrier to enable it to be located over the screw
heads before it is lowered onto the M4 fixings.
TOP clearance when mounted Horizontally.
TOP clearance when mounted Vertically.

Figure 4.4 - Surface-mount hole positions and dimensions
The four M4 fixing screws should be screwed into the (panel) surface leaving
approximately 5–6mm of thread visible between the screw head and panel. Mount
the carrier over the heads of the screw fixings and then lower it into position.
Four holes in the carrier circuit board, indicated as ‘A’ in Figure 4.3, provide screwdriver
access to the four fixings screw once the carrier is mounted. These holes are always
visible and do not require the removal of any modules.
Tighten the screws to the recommended torque of 0.5Nm.
On completing the mounting procedure, confirm:
• that the assembly has not suffered any structural damage,
• the carrier has not been distorted,
• all mounting screws are tightened as recommended.
Removal is the reverse of the fitting procedure.

5 ELECTRICAL CONNECTIONS
The DC power, Host and Field Segment connectors are pluggable and available in a screw
terminal version (-PS) or a spring-clamp version (-PC). See Figures 5.1 & 5.2 for details.
The terminals can accept the following conductor sizes:
Type Conductor size
Screw terminals (-PS) 0.14 to 2.5mm2
Spring-clamp terminals (-PC) 0.2 to 2.5mm2
Figure 5.1 - Screw terminal Figure 5.2 - Spring-clamp
NOTE
1. A torque screwdriver set between 0.5- 0.6Nm is recommended for tightening all
terminal wiring screws and terminal securing screws.
2. When wiring to spring-clamp terminals, use a screwdriver with a 3-4 mm blade and
depress the spring-clamp button before inserting the termination cable. See Figure 5.2.
5.1 DC Power Requirements
Dual redundant power terminals, requiring a nominal input voltage of 24VDC, are
provided – Power A and Power B – allowing the use of bulk power supplies with a
supply range of 19.2–30V DC. Input power cabling and over-current protection devices
must be chosen to match the current consumption.
NOTE
The bulk power supply must comply with electrical safety standards IEC 61010 or
IEC 60950. Apparatus carrying a CE mark will comply with this requirement.
A 9189-61-P* system, operating with four redundant 9191-FP modules at 24VDC, will
require 2.9A in total with all outputs fully loaded. With six redundant 9191-FP modules
(9189-91-P* system) at 24VDC, it will require 5.7A.
A 9189-62-P* system, operating with four redundant 9192-FP modules at 24VDC, will
require 2.1A in total with all outputs fully loaded. With six 9192-FP modules (9189-92-
P* system) at 24VDC, it will require 4.1A.
NOTE
The current demand from Power A or Power B will depend upon the modules
inserted. See Section 2.2 for further information on power distribution.
5.2 Power A and Power B
Power A and Power B supplies are distributed on the carrier as described in Section
2.2. DC supply connections are as follows:
Power A Power B
Pin No. Connection Pin No. Connection
1+ve 32 +ve
2-ve 33 -ve
Cable lengths on the Power connectors should not exceed 30m.

5.5 Grounding
Carrier terminals 17 (‘SG’) and 19 (‘G’) should both be connected to a clean electrical
ground in the power supply cabinet and all (host and field) cable screens should be
connected to their individual ‘S’ terminals.
5.5.1 Screens grounded at supply
If the design policy is to ground the fieldbus cable screens at the fieldbus power
supply, then the “Shield” jumper should then be inserted in the connector as shown
in Figure 5.3a. This will bring all of the shields to a common connection at the ‘SG’
terminal (17)and therefore to ground.
5.5.2 Screens grounded at other location on segment
In this situation the “Shield” jumper should be inserted in the connector as shown in
Figure 5.3b.This option keeps the individual segment screens isolated from each other
and the local ground, permiting an alternative choice of grounding method.

5.6 Power Modules
WARNING !
The 919x-FP Power Module can be “hot-swapped” without the risk of damaging
it, but a gas clearance certificate is required to carry out this action in a Zone 2
hazardous area or Division 2. See “Special conditions for Safe Use” on page 14.
Le module de puissance 919x-FP peut être “remplacé à chaud” sans risque
de l’endommager, mais un permis de feu est exigé pour effectuer cette action
dans une zone de danger classée Zone 2 ou Division 2. Voir “Conditions
particulières pour une sécurité d’utilisation” en page 14.
The 919x-FP Power Modules are secured to the carrier with two captive screws.
Orientate the module to enable it to fit onto the carrier-mounted mating connectors.
When mounted, tighten the two captive screws to secure the module.
NOTE
A 9197-BLK Alarm Blanking Module is required in any location where a 919x-FP module
is not fitted in order to maintain alarm wiring continuity.
5.7 Redundancy
For 250mA per segment requirements, a single 919x-FP module will provide the
necessary power for 4 segments. For 500mA per segment, two 919x-FP modules are
required. For n+1 redundancy, one additional power module (per four segments) is
needed as described in Section 2.2.
Redundant systems are available as:
4-segment 8-segment Available current
9189 -2x-P* 9189-6x-P* 250mA per segment
9189 -4x-P* 9189-9x-P* 500mA per segment
5.8 Terminator
Each segment is provided with its own permanent terminator on the circuit board
without intervention by the user.
5.9 Alarm connection
See Section 2.3 on page 4 for further details of the alarm function.
The alarm connections are provided at
terminal numbers 15 and 16. Although
labelled as ‘+’ and ‘–’ the terminals are
not polarity sensitive.
Figure 5.5 illustrates how the switches
contained within the 919x-FP modules
are interlinked on the carrier.

should be filled with a blanking module (part number: 9197-BLK). This will maintain
continuity of the “alarm circuit” through the carrier by bridging the missing
connection, normally provided by the module. This prevents a permanent alarm state
from existing on the carrier and enables “genuine” alarm events to continue to be
signalled.
If multiple 9189 systems are used, a common alarm circuit can be created by
connecting the alarm terminals in series (“daisy-chaining”)- see Figure 5.6.

5.10 Diagnostic segment connections
The F809F-Plus fieldbus diagnostic module may be configured to communicate
on segment 1 or 8 of the monitored fieldbus segments, or on a separate fieldbus
segment. If it is configured to communicate on a segment specifically used for the
collection of diagnostic data, then terminals 63 to 65 and 66 to 68 enable it to be
connected in-line on that segment.

7 ROUTINE MAINTENANCE
Check the general condition of the installation occasionally to make sure that no
deterioration has occurred. At least every twoyears (and more frequently for particularly
harsh environments) check:
• the condition of wire connections, terminations, and screens.
• the DC output voltage on each of the eight fieldbus segments is >28V for power
supplies fitted with 9191-FP modules or >19v for power supplies fitted with 9192-
FP modules. This can be performed using a multi-meter or a MTL FBT-6 Fieldbus
Monitor.
• the segment LEDs on the Power Module(s) are ON and the Alarm LED is OFF.
• the Power Module/Blanking Module retaining screws are tight.
• there are no signs of damage or corrosion.
