mount the controller on a DIN rail and how to mount the
controller on an enclosure base plate.
Mounting locations to avoid
• Areas with excessive moisture, corrosive fumes, or
explosion vapors
• Locations where excessive vibration or shock occurs
• Locations with excessive electrical noise, such as
large magnetic interference or variable speed drive
modules
Mounting the controller on a 35mm DIN
rail
1. Mount a section of 35 mm (1.38 in.) DIN rail
horizontally on the enclosure base plate.
Figure 4: 35 mm DIN rail
2. Pull the bottom mounting clip outward from the
controller to the extended position.
Figure 5: Pulling the mounting clip outwards
3. Hang the controller on the DIN rail by the hooks at
the top of the DIN rail channel on the back of the
controller and position the controller firmly against
the DIN rail.
Figure 6: Placing the controller on the DIN rail
4. To secure the controller to the DIN rail, push the
mounting clips up.
Figure 7: Closing the mounting clips (rear view)
FW-14 Quick Start Guide2
5. Optional: For added security, use DIN rail end
clips. For the location if the DIN rail end clips, see
Figure 1.
Mounting the controller to an enclosure
base plate
About this task:
If a DIN rail mount is not practical, the controller features
two mounting holes to screw mount the controller to an
enclosure base plate.
1. Place the controller on the enclosure surface and
mark the enclosure mounting holes on the surface.
For more information, see Enclosure mounting
holes in Figure .
2. Drill both holes in the enclosure base plate.
3. Screw the controller to the enclosure base plate.
Installing the antennas
1. Locate the two RP-SMA female jacks. See Figure 1.
2. To connect the male antenna connectors to the
female RP-SMA jacks, screw on the antennas in a
clockwise direction.
Note: For a secure connection hold the metal
part of the RP-SMA male connector. A poor
connection reduces reception when you
tighten the antennas to the female RP-SMA
jack.
Figure 8: Screwing on the antennas
3. Adjust the direction of the antennas to find the best
reception. For more information about antenna
reception, refer to Wireless Network (Wi-Fi) in EasyIO
FW Series Network Connectivity.

CAUTION
Complete the wiring and check all wiring connections
before you connect the power supply to the controller,
because short circuits or wires connected incorrectly
can cause damage to controllers and void warranties.
CAUTION
Do not exceed controller electrical ratings, because
this can result in permanent damage to the controller
and void warranties.
Important
Only use copper conductors. Wire the controller
in accordance with local, national, and regional
regulations
CAUTION
Use the correct electrostatic discharge precautions
throughout installation, setup, and service to avoid
damage to the controller and controller components.

Power supply terminal wiring
Connect the 24 VAC supply power wires from the
transformer to the HOT and COM power terminals as
shown in Figure 18.
Note: The supply power wire colors may differ on
transformers from other manufacturers. Refer to
the transformer manufacturer’s instructions and the
project installation drawings for wiring details.
Important: To reduce noise, interference, and
ground loop problems, connect a 24 VAC supply
power to the controller and to all other network
devices so that transformer phasing is uniform
across network devices. The controller does not
require an earth ground connection. However, when
you need to ground the secondary of the 24 VAC
transformer, make only one ground connection
near the transformer. For more information, see the
following figure.
Figure 18: Transformer grounding
CAUTION
To avoid property damage, check all wiring
connections before you apply power to the system.
If you wire this terminal incorrectly, a short circuit
can occur across the 24 VAC power supply on the
controller. A short circuit can cause a tripped circuit
breaker or a blown fuse. If you use a transformer
with a built-in fuse, you may need to replace the
transformer.
Input and output terminal wiring
considerations
• Run all low-voltage wiring and cables separate from
high-voltage wiring.
• For all input and output cables, use twisted, insulated,
and stranded copper wires.
• Use shielded cables for input and output cables
that are exposed to high electromagnetic or radio
frequency noise.
• Cable runs over 30 m or 100 ft require an offset in the
input and output software setup.
RS-485 bus terminals
Wire the RS-485 terminals in a daisy-chain configuration.
Use a stranded three-wire twisted and shielded cable
as shown in Figure 19. The three different wires are the
positive bus, the negative bus, and the COM.
You can use the RS-485 positive and negative wires as
sensor actuator (SA) bus +ve and SA bus -ve.

Troubleshooting
Table 4: FW troubleshooting
Problem Cause Solution
The transformer shorted.
The 24 VAC powered sensor is not wired
with the same polarity as the controller.
The controller does not turn
on due to one of the following
problems:
• The transformer trips. Power
is at the transformer primary
and there is no voltage at
the secondary.
• The breaker or fuse trips.
Power is at transformer
primary. You find 24 V
at secondary and 0 V at
breaker or fuse.
The RS-485 bus device is not wired with
the same polarity as the controller.
1. Ensure that the polarity of ~24 V COM, +15 V COM, and
SA BUS COM on the controller, auxiliary devices, and
input and output devices is the same.
2. Verify that the short circuit is resolved with an ohm-
meter.
3. Reset the breaker or fuse, or replace the transformer.
Note: If you replace the transformer, replace
it with a model that uses a resettable circuit
breaker. A circuit breaker makes it easier to solve
wiring problems.
4. To verify the connection, complete the following steps:
a. Disconnect the secondary of the 24 VAC
transformer.
b. Use an ohm-meter to measure between ~24 V H
and G at the controller. Ensure that no short circuit
occurs.
Note: If your installation requires that you
earth ground the transformer secondary,
verify that the earth ground connection
is valid and not shared between multiple
pieces of equipment.
Analog output mode is invalid. 0
V to 10 V output is set to 100%,
but output terminals are less
than 10 V.
Load impedance is lower than 2K ohms. 1. Ensure that the voltage control device load impedance
is higher than 2,000 ohms. For more information, refer
to voltage device manufacturer specification.
2. Disconnect the connected device and verify that the
value you require is present.
Analog mode for a configurable
output is invalid. For example,
0 V to 10 V output results in an
unwanted offset of up to 1 V.
The Common Reference is
incorrect.
The COM terminal is not connected. 1. Connect the COM terminal of the configurable output
to the common of the connected end device.
2. Measure the output and verify that it matches the
command.
3. Disconnect the connected device and verify the
commanded value is present.
