Mounting
You can mount each controller on a DIN rail, on a wall, or in a panel. The controllers are equipped with two
mounting holes 0.25 x 0.165 in. (6.36 x 4.191 mm).
Location Considerations
Observe these guidelines when mounting an LN Application Specific or Remote I/O Module:
• Provide for sufficient space around the device for cable and wire connections, access to service pin, hardware
configuration, maintenance, easy cover removal, and good ventilation.
• Ensure proper ventilation of each device and avoid areas where corroding, deteriorating, or explosive vapors,
fumes, or gases may be present.
• Orient each controller with the ventilation slots and power supply/output terminal block connector towards the
top to permit proper heat dissipation.
• Do not mount the controller on surfaces prone to vibration, such as duct work, or in areas where
electromagnetic emissions from other devices or wiring can interfere with communication.
DIN Rail
To mount the controller on a DIN rail:
1. Ensure the DIN rail is properly mounted on the wall.
2. Clip the controller onto the DIN rail.
Wall Mount
To mount the device on a wall:
1. Press on the side clips to separate the device’s front and back plates.
2. Use the holes on the back plate to mark the wall location.
3. Drill the holes.
4. Clean the surface and mount the unit using the appropriate screws.

Wiring
Follow these wiring recommendations:
• Remove the front plate from the back plate to facilitate in the wiring process. Use a small flat screwdriver to
tighten the terminal connector screws once you have inserted the wires.
• Keep power cables apart from other types of wiring to avoid ambient noise transmission to other wires (for
example, for power, 3-wire voltage, and current inputs and outputs).
• Use wires or flat cables ranging from 22 to 12AWG (0.645 to 2.052 mm diameter) per pole. Power cables must
remain between 18 to 14AWG (1.024 to 1.628 mm) diameter.
• Keep all wires away from high-speed data transmission cables (for example, Ethernet cable).
• Keep input and output wires in conduits, trays, or close to the building frame whenever possible.
Power Wiring
For more information and requirements for powering a device that uses a LONWORKS network for communications,
refer to the LONWORKS LN-Series Network Communication and Interface Guide Technical Bulletin (LIT-12011253).
We recommend wiring only one device per 24 VAC transformer. When only one transformer is available, determine
the maximum number of devices that can be supplied using the following method for calculating the required power
transformer capacity:
1. Add up the maximum power consumption of all controllers and multiply this sum by 1.3.
2. If the resulting number is higher than 100 VA, consider using multiple transformers.
Use an external fuse on the 24 VAC/DC side (secondary side) of the transformer to protect all units against power
link spikes (Figure 3).
Maintain consistent polarity when you connect the controllers (or modules) and devices to the transformer.
Risk of Electric Shock.
Disconnect the power supply before making electrical connections to avoid electric shock.
Risque de décharge électrique.
Débrancher l'alimentation avant de réaliser tout raccordement électrique afin d'éviter tout risque de décharge
électrique.
IMPORTANT: All wiring must comply with electrical diagrams as well as national and local electrical codes.
IMPORTANT: Voltage: 24 VAC/DC; +15%, Class 2. This is a Class 2 Product. Use a Class 2 transformer only
(rated at 100 VA or less at 24 VAC) to power the device.
IMPORTANT: Failure to maintain consistent polarity throughout the entire network will result in a short circuit
and damage to the controller.
IMPORTANT: The COM terminals of the controller are internally wired to the 24 V COM terminal of the power
supply. Connecting a peripheral or another controller to the same transformer without maintaining polarity
between these devices will cause a short circuit.

LN Application Specific, Remote I/O, and Free Programmable Controllers Installation Instructions

Use an external fuse on the 24 VAC/DC side (secondary side) of the transformer to protect all controllers against
power link spikes.
Input Wiring
The devices have physical connections for inputs (marked Ulx), which are software configurable from within the
device’s LNS® plug-in or wizard. Therefore, hardware configuration is not required.
Each input can be configured for digital, resistive, current, or voltage signals. You must configure the input types
properly in the software plug-in or wizard to ensure proper input readings.
Note: For a wire of less than 75 feet (23 m), use either a shielded or unshielded 19AWG wire.
Note: For a wire from 75 feet (23 m) to 200 feet (61 m), we recommend a shielded 18 AWG wire.
Note: The wire should be shielded on the controller or module side, and the shield length should be kept as short
as possible.
Wiring Digital Inputs
Use the input configuration in Figure 5 to monitor digital dry contacts.
IMPORTANT: Before connecting any sensor to the device, refer to the installation guide of the equipment
manufacturer.

Wiring Resistive Inputs
Use this input configuration to monitor 100k ohm RTDs, 10k ohm Type 2 and Type 3 thermistors, and
potentiometers (Figure 6 and Figure 7).
Note: The Application Specific Controllers do not support 100 or 1,000 ohm inputs.
Note: When using a 100 ohm input, the wire length should be kept short to avoid a possible temperature offset; for
example, an 18AWG wire, 25 feet long (7.6 m) can create an offset of 2°F (1.1°C).

Wiring Current Inputs
Current inputs have a range of 4 to 20 mA. Connect the current input according to Figure 8 if you are using a
2-wire, 4-20 mA transducer.
Connect the current input according to Figure 9 if you are using a 3-wire, 4-20 mAtransducer.
Connect the current input according to Figure 10 if you are using a transducer powered by its own power.
Wiring Voltage Inputs
Voltage inputs have a range of 0 to 10 VDC. Connect the voltage input according to Figure 11 if you are using a 3-
wire 0 to 10 V transducer.
Output Wiring
Each controller has physical connections for triac outputs and/or universal outputs, depending on the type and
model. The outputs are all software configurable. Table 1 shows the controller outputs.

Note: For wire length less than 75 feet (23 m), use either a shielded or unshielded 19 AWG wire.
Note: For a wire up to 200 feet (61 m), we recommend a shielded 18 AWG wire.
Note: The wire should be shielded on the controller/module side, and the shield length should be kept as short as
possible.
Wiring Triac Outputs
Digital outputs are all made of triacs and voltage is no present on the output terminals; therefore, you need to add
an external power source, if necessary.
Note: You must add an external power source, typically 24 VAC.
If a 24 VAC relay is being controlled, connect the digital output according to Figure 12.
If a floating actuator is being controlled, connect the digital output according to Figure 13.
Wiring Universal Outputs (UOx)
Universal outputs can be configured to provide either a linear signal ranging from 0 to 12 VDC or a linear signal of
0 to 10 VDC. The discrete signal can be used to generate a PWM or a simple two-state signal. These outputs are
protected by an auto-reset fuse.
When controlling a relay with a universal output, a diode must be connected in parallel to protect the controller from
back-emf current that occurs when the relay is turned off.

Wiring Discrete Outputs
If a 12 VDC relay is being controlled, connect it to a universal output according to Figure 14.
Wiring Voltage Inputs
Connect the 0 to 10 VDC output according to Figure 15.
If an analog actuator is being controlled, connect the 0 to 10 VDC output, along with an external 24 VAC power
source, to the analog actuator according to Figure 16.
Two network terminators are required for the bus topology network configuration. Place one network terminator at
each end of the bus topology channel.
One network terminator is required for the free topology network configuration. You can put the network terminator
anywhere on the channel.
Communications Wiring
The recommended cable type for LONWORKS® communications is 22AWG (0.65 mm), twisted pair, UNSHIELDED
wire. The LONWORKS communication wire is polarity insensitive and can be laid out in a bus, star, or free topology.
For loop topology, take special care to maintain the polarity when connecting the LONWORKS network to avoid a
short circuit.
Note: We recommend you use the bus topology network configuration for all LONWORKS communication wiring.
This configuration allows you to troubleshoot the network easily.

Connect both wires to the LON terminals (LON1 and LON2) of the controller (Figure 17). When you insert multiple
wires into the terminals, ensure you properly twist the wires together before you insert them into the terminal
connectors.
For more information and detailed explanations on network topology and wire length restrictions, refer to the
LONWORKS LN-Series Network Communication and Interface Guide Technical Bulletin (LIT-12011253) or Echelon
Corporation’s Junction Box and Wiring Guideline for Twisted Pair LONWORKS® Networks.
LN Sensor Wiring
The controllers in this document are compatible with the LN Sensor line of standard room sensors. Refer to the LN
Series Sensor Installation Instructions (LIT-1201871) for wiring details.
Memory Erase Jumper
Each Application Specific Controller and Remote I/O Module features a memory erase jumper. Use the memory
erase jumper to erase the Neuron chip's memory. If an incorrect APB or NXE file is loaded into the device, the
Neuron chip's memory is corrupted and you cannot communicate with the device. Use the memory erase jumper to
correct this problem by resetting the Neuron chip's memory; the chip is then in an application-less state.
The memory erase jumper is labeled J2 on the Application Specific Controllers (Figure 19), J4 on the LN-IO301-1
Remote I/O Module (Figure 20), and J20 on the LN-IO401-1 and LN-IO520-1 Remote I/O Modules (Figure 18).
To erase the Neuron chip's memory using the memory erase jumper, do the following:
1. Disconnect the power to the device.
2. Place a jumper on the proper pins on the controller or module.
3. Reconnect the power to the device.
Note: The orange colored service LED blinks rapidly indicating that it is erasing the Neuron chip’s memory. When
the service LED stops blinking and remains solid, the erase procedure is complete.
Note: The erase procedure normally takes between 2 and 10 seconds to complete.
4. Disconnect the power to the device and remove the jumper.
5. Reconnect the power. The service LED blinks twice and becomes solid indicating the controller or module is
application-less.
6. Download the correct APB file.
IMPORTANT: Use the proper network terminators for the network topology. Failure to use the correct network
terminators may result in communication errors between units. Do not use multiple gauges of cable on the same
communication bus.

Strain Relief and Terminal Block Cover
In certain jurisdictions, terminal block covers are required to meet local safety regulations. Strain reliefs and
terminal block covers are availablefor controllers housed in the large enclosures and are used to relieve tension on
the wiring and conceal the controllers' wire terminals. Strain reliefs and terminal block covers are optional and are
sold separately.
Prior to connecting all wires, it is recommended that you install the strain relief. Three screws are provided for its
installation under the bottom part of the enclosure. You can then use tie wraps to group wires together and attach
them securely to the strain relief in an effort to relieve undue tension. If necessary, clip the terminal block cover to
the strain relief as shown in Figure 21.

Maintenance
Each controller requires minimal maintenance, but it is important to:
• clean the outside of the front plate an/or the inside of the back plate, use a dry cloth.
• verify the tension of all wires and cables each time you service the controller.
Disposal
The Waste Electrical and Electronic Equipment (WEEE) Directive sets regulations for the recycling and disposal of
products. The WEEE2002/96/EG Directive applies to stand-alone products that can function on their own and are
not a part of another system or piece of equipment.
For this reason, Johnson Controls® products are exempt from the WEEE Directive. Nevertheless, they are marked
with the WEEE symbol, indicating the devices are not disposed with municipal waste.
Dispose of products at the end of their useful life according to local regulations and the WEEE Directive.
