OPERATING INSTRUCTIONS  
FP-PS-4  
FieldPoint Power Supply  
These operating instructions describe the installation, features, and  
characteristics of the FP-PS-4.  
Features  
The FP-PS-4 is a FieldPoint power supply module with the  
following features:  
24 VDC output  
Convenient DIN rail mounting or optional panel mounting  
Universal AC power input: 90 to 264 VAC, 47 to 63 Hz  
Modular FieldPoint form factor for easy integration with other  
FieldPoint modules  
15 W output for 0 to 50 °C operation  
Installation  
You can mount your FieldPoint system either to a DIN rail or  
directly on a panel. The following sections give instructions for  
both mounting methods.  
Mounting Your FP-PS-4 on a DIN Rail  
The FP-PS-4 power supply module has a simple rail clip for  
reliable mounting onto a standard 35 mm DIN rail. Follow these  
steps to mount the module on a DIN rail.

3. Slide the FP-PS-4 to the desired position along the DIN rail.  
For maximum cooling, leave a 25 mm (1.0 in.) space between  
the FP-PS-4 and other devices on your DIN rail. After it is in  
position, lock it to the DIN rail by pushing the rail clip to the  
locked position, as shown in Figure 3.

Mounting Your FP-PS-4 on a Panel  
Follow these steps to install the optional FieldPoint network panel  
mount accessory and mount the FP-PS-4 power supply module to  
a panel. You can order the panel mount accessory, part number  
777609-01, from National Instruments.  
1. Use a flat-bladed screwdriver to unlock the rail clip, as shown  
in Figure 1.  
2. Attach the panel mount accessory to the module, as shown in  
Figure 4.  
Figure 4. Installing the Panel Mount Accessory  
3. Lock the panel mount accessory into place by pushing the rail  
clip to the locked position.

4. Mount the FP-PS-4 to your panel with the panel mount  
accessory, as shown in Figure 5. The installation guide that  
comes with the panel mount accessory includes a template that  
you can use to drill pilot holes for mounting FieldPoint  
modules. For maximum cooling, leave a 25 mm (1.0 in.) space  
between the FP-PS-4 and other devices.

Connecting Power to Your  
FieldPoint System  
Caution Before you connect the FP-PS-4 to your  
FieldPoint system, make sure the power cord is not  
plugged into an electrical outlet.  
Each FP-PS-4 provides a 24 VDC output. You decide the number  
of FP-PS-4 modules you need in your bank based upon the specific  
power and isolation requirements. The total power of all of the  
FieldPoint modules and other devices connected to an FP-PS-4  
cannot exceed the specified output for the temperature range at  
which you are using FP-PS-4. For FieldPoint power requirement  
details, refer to the operating instructions for your particular I/O  
modules. Decide how you want to power your FieldPoint bank  
based on the power requirements of your bank and your isolation

needs. Select one or a combination of the methods to power the  
signals of each of your I/O modules:  
The signals of the I/O module are powered by an FP-PS-4 that  
is connected to only that I/O module.  
The signals of the I/O module share an FP-PS-4 with a  
neighboring I/O module or network module. This is called  
cascading power.  
Caution Cascading power from neighboring bases or  
network modules defeats isolation between cascaded  
modules.  
Figure 6 shows a combination of the two ways to power the  
FieldPoint bank.

Figure 6. Wiring Power to Your FieldPoint Bank  
In Figure 6, the FP-PS-4 bank provides the power using both of the  
methods mentioned previously. The FP-2000 and FP-AO-200 have  
their own power supplies. Isolation is maintained because the  
FP-AO-200 has its own power supply. The FP-RLY-420 and  
FP-DO-400 share a power supply, which provides enough power,  
but defeats isolation between the signals of those two modules.

Ensure that all the wiring is installed according to local codes and  
regulations by qualified electrical personnel. Follow these steps to  
connect the FP-PS-4 to your FieldPoint system.  
1. Use a 16 to 26 AWG stranded wire to connect the FP-PS-4 to  
your FieldPoint network module or I/O module. Connect the  
positive wire to the V terminal and the negative wire to the  
C terminal of the FP-PS-4.  
2. Connect the other ends of the wires to the V and C terminals of  
the FieldPoint network module or I/O module.  
3. Ensure that the plug-in AC input terminal connector is plugged  
into the input port on the FP-PS-4.  
Note Be careful to install the correct conductor in the  
appropriate terminal. The color of the conductor wires  
varies depending on North American versus international  
standards as described in Figure 7. The wires are drawn  
to scale according to the 7 mm (0.275 in.) strip length  
requirement.

6. Connect the green or green/yellow conductor into the ground  
terminal.  
Caution When you install the conductors, make sure that  
the entire conductor is in the screw terminal and that there  
are no loose strands outside of the terminal. Only install  
one wire in each terminal.
