1 OVERVIEW
The F101, F102, and F104 (F10x) Fieldbus Power Supplies are designed to provide power
for a single FOUNDATION fieldbus™ H1 or Profibus PA segment. Galvanic isolation, power
conditioning and segment termination are incorporated into each F10x module. Termination
of the fieldbus segments is normally enabled with a switch on the module, but may be
switched off for those few applications that do not require aTerminator at the Fieldbus Power
Supply.
2 DESCRIPTION
For extreme reliability, the modules use passive components for power conditioning and a
reliable DC/DC converter to provide galvanic isolation and power regulation. The connectors
used for power input and the Fieldbus output are high quality pluggable types with screw
retention. Spring-clamp (-PC) and screw terminal (-PS) connector versions are supported.
LED indicators show the status of the modules. In normal operation, the green Power LED
is lit, showing that there is proper input voltage to the module and the red Fault LED is off.
If the fieldbus segment is shorted or in an over-current condition the Fault LED blinks. An
internal module error is indicated by a steady light on the red Fault LED. The status of the
internal terminator switch is also indicated by an illuminated ‘T’ symbol.
The modules can be powered from a supply between 19.2 – 30.0 VDC (10.0 – 30.0 VDC
for the F104). The incoming power can be applied via the top-mounted connector which
supports onward looping of power wiring, or by using a proprietary plug-in connector on a
DIN-rail bussing system.

4.1 Mounting Orientation
The F10x Fieldbus Power Supplies are designed for mounting on a horizontally aligned
DIN-rail on a vertical surface. This method of mounting ensures optimum heat
dissipation.
4.2 Enclosure Requirements
4.2.1 General Requirements
The assembly may be mounted in hazardous (classified) areas – see Sections 8 & 9.
The following conditions must also be satisfied to ensure safe and reliable operation.
a) 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.
b) Provide an adequate level of mechanical protection. This can be achieved by
selecting a protected location, a suitable enclosure, or a combination of both.
c) Ensure that all cable entries and connections are secure by making provision for
the careful routing and securing of all cables.
d) Provide adequate security against unauthorized interference.
e) Ensure that the permitted ambient temperature range of –40°C to +65°C (+70°C
if load is 400mA or less) is not exceeded. Allow for power dissipation within the
enclosure and consider the use of shading against direct sunlight.

3INM F10x Rev 1
4.2.2 Outdoor Mounting
If the F10x 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.
4.3 DIN-rail Mounting
The F10x is designed for mounting on 35mm x 7.5mm T-section “top hat” DIN rail to
EN50022 and uses an integrated DIN-rail clamp to hold it onto the rail. If the DIN-rail
bussing system is to be used, the bussing connectors must first be attached to the
DIN-rail.
For vertical DIN Rail installations, we recommend using a DIN Rail clamp below the
F10x modules (see accessory PBUS03) to prevent the units from sliding on the DIN
Rail.
4.3.1 Mounting Procedure
The F10x is mounted to the DIN-rail by hooking the side opposite the DIN-rail latch to
the DIN Rail. The device is then pivoted to fit on the DIN-rail. Then the latch is pushed
toward the DIN-rail and snaps in place holding the F10x firmly on the DIN-rail.
For applications using the DIN-rail bussing connectors, the DIN-rail bussing connector
must first be snapped onto the DIN Rail – see Figure 4a. The F10x is then installed
over the DIN-rail bussing connector making sure that it is properly lined up (Figure 4b).
Figure 4a

Figure 4b
4.4 Removal from DIN-rail
To remove the F10x from the DIN-rail, use a screwdriver to release the DIN-rail latching
mechanism. Pivot the F10x and remove from the DIN-rail.
5 ELECTRICAL CONNECTIONS
The Input power and Fieldbus Segment connectors are pluggable and available in a
screw terminal version (-PS) or a spring clamp version (-PC). See Figures 5a & 5b. 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 5a: Screw Terminal Figure 5b: Spring Clamp
NOTE
When wiring to spring-clamp terminals use a screwdriver with a 3-4 mm blade
and depress the spring-clamp button (orange) before inserting the termination
cable. See Figure 5b.

5INM F10x Rev 1
5.1 DC Power Requirements
Power terminals requiring a nominal input voltage of 24VDC are provided allowing the
use of bulk power supplies with a supply range of 19.2–30VDC (10–30VDC for the
F104). Input power cabling and over-current protection devices must be chosen to
match the current consumption.
Typical input current at 24VDC input for a fully loaded F10x is shown in the table below.
The input current is load and input voltage dependent. To determine the expected
input current for a specific application, see the graphs in the F10x Product Specification
document. If the power is ‘daisy-chained’ using the top-mounted F10x connectors,
size the input fusing accordingly and keep the total current below 8A. Each F10x
module contains an internal 1.5A fuse (not user replaceable).
Module Input Current
F101 550mA
F102 700mA
F104 200mA
It is also important to size the Bulk Power Supply to handle the inrush current required
by the F10x. Inrush is less than 3 times the maximum rated current with a duration
lasting less than 2ms.
5.2 Power Connector Wiring
There are two pairs of positive and negative terminals on the input power connector.
The pairs are internally connected together to allow ‘daisy-chaining’ of power from
one unit to another. Wiring of two independent power supplies (for redundancy) to the
input power connector is not permitted unless external steering diodes are included in
each source of supply. DC supply connections are as follows:
Input Power
Pin No. Connection
7+ve
8-ve
9+ve
10 -ve
Cable lengths on the Power connectors should not exceed 30m nor go outside the
building.
It is important to note that because the input wire pairs are internally connected on
the F10x printed circuit board, unplugging the 4 way connector will disrupt the daisy
chained power. To prevent unexpected loss of power downstream of the F10x, the
bulk power should be routed to each end of the daisy chain. This way, unplugging one
F10x 4 way connector will not disrupt other devices.

6INM F10x Rev 1
5.3 DIN-rail bussing
Rather than using the top 4 way connectors to provide power to the F10x, an optional
DIN-rail bussing system is available. This is very convenient when multiple F10x units
are in the same cabinet. One DIN-rail bussing connector is needed for each F10x
module. In addition a Female and/or Male connector that mates to the DIN-rail bussing
connector is needed to wire the input power to the series of bussing connectors. Use
a Female on one end and a male on the other to buss power from both directions
in case the string of bussing connectors might need to be separated at some time.
There is also an end stop/cable strain relief device that is available – see the accessory
parts in section 3.
Power supplied to the DIN-rail bussing chain should be limited by a fuse to 8A
maximum. Use the table in section 5.1 to determine the maximum number of F10x
modules that can be connected in one DIN-rail bussing chain.
Figure 5c
5.4 Terminator
The F10x module contains a Terminator that is activated by a switch. The Terminator
switch is in the ON position from the factory. Graphics on the label on the side of
the F10x indicates the switch location and the orientation that enables and disables
the Terminator – see Figure 5d. A white LED illuminates a “T” on the top of the
unit whenever the Terminator is enabled – see Figure 5e. Most applications will take
advantage of the internal Terminator in the F10x.
