Mounting
Location Considerations
Follow these guidelines when mounting an NAE55:
• Ensure that the mounting surface can support the
NAE55 and any user-supplied enclosure.
•
Mount the NAE55 in the proper orientation (Figure
4).
• Mount the NAE55 on an even surface in wall mount
applications whenever possible. If you must mount
the NAE55 on an uneven surface, be careful not to
crack the wall mount feet or housing when tightening
the screws. Use shims or washers to mount the unit
securely on the mounting surface.
• Mount the NAE55 in areas free of corrosive vapors
and observe the environmental limitations listed in
the Technical Specifications section.
• Do not mount the NAE55 on surfaces that are prone
to vibration, such as duct work, or in areas where
electromagnetic emissions from other devices or
wiring can interfere with NAE55 communication.
• Allow sufficient space for running cable and wire,
making terminal connections, and accessing battery
compartment (Figure 2).
• Do not mount the power supply below the NAE55.
On panel or enclosure mount applications, observe these
additional guidelines:
• Do not install the NAE55 in an airtight enclosure.
• Mount the NAE55 so that the enclosure wall or the
transformer does not obstruct ventilation of the NAE55
housing.
Each NAE55 application is different, and no general
guidelines can be given about the heat dissipating devices
that may be mounted in an enclosure with the NAE55.
Monitor the NAE55 processor temperature for each
application to determine the acceptable combinations of
devices and proper mounting location for your specific
application.
Important: Do not add any devices to an enclosure with
an NAE55 that could cause the temperature
of the NAE55 processor to exceed 70˚C
(158˚F). View the NAE55’s CPU
Temperature value on the NAE55’s
Diagnostic tab on the Metasys® Site
Management Portal. See Technical
Specifications for ambient condition
requirements, and refer to the
Troubleshooting section of the NAE
Commissioning Guide (LIT-1201519) for
additional information.
Mounting the NAE55
Wall Mount Applications
To Mount the NAE55 on a vertical surface:
1. Mark the location of the four wall mount feet on the
wall using the dimensions in Figure 3 and an
orientation shown in Figure 4, or hold the NAE55 up
to the wall and mark the hole locations.
Figure 3: Mounting Screw Hole Dimensions,
mm (in.)
Figure 2: NAE55 DIN Rail Mount Dimensions and
Mounting Space Requirements, mm (in.)
2. Drill holes in the wall at the marked locations.
3. Insert appropriate wall anchors in all four holes (if
necessary) and insert the screws into the top two
holes. Leave enough space between the wall surface
and the screw head for the wall mount feet.
4. Hang the NAE55 on the screws with the top wall
mount feet for horizontal wall mount applications. Hold
the NAE55 in place for vertical application.
3NAE55/NIE55 Installation Instructions
Note: The wall mount feet are designed to make
mounting easier. When the NAE55 is wall
mounted in the BEST (horizontal) orientation,
you can hang the NAE55 on the screws with
the upper two mount feet.
5. Insert the screws into the lower two wall mount feet
and holes and carefully tighten all of the screws.
Important: Do not overtighten the mounting screws.
Overtightening the screws can crack the
NAE55 wall mount feet or housing.
DIN Rail Mount Applications
To mount the NAE55 on DIN rails:
1. Mount two DIN rails horizontally, so they are 125 mm
(4.9 in.) apart on centers (Figure 2).
2. Snap the DIN clips on the bottom of the NAE55 to the
outward position.
3. Hang the NAE55 on the DIN rail hooks on the back
of the NAE55.
Press the DIN clips back into position to secure the unit
on the DIN rails.

Wiring
Power Supply, Network, and Communication Connections
See Figure 1 for the location of the power supply terminal,
network communication terminals, Ethernet jack, and
modem jack.
Power Supply
Important: Install the data protection battery before
applying 24 VAC power to the NAE55. See
the Installing the Data Protection Battery
section.
In North America, use a Class 2, 24 VAC power supply
with a 50 VA minimum output. Outside North America,
use a 24 VAC Safety Extra-Low Voltage (SELV)
transformer at the appropriate rating. The minimum input
voltage for the NAE55 to operate properly is 20 VAC.
See the Technical Specifications section.
Use a dedicated power supply to the NAE55 only. Do not
connect any other loads to the power supply. Additional
loads may cause noise interference.
FC Bus Terminal Block
The two Field Controllers (FCs) Bus connections on the
MS-NAE55xx-x models are 4-pin removable, keyed
terminal blocks labeled FC A and FC B.
To remove the NAE55 from the DIN rails:
1. Snap the DIN clips on the bottom of the NAE55 to the
outward position.
2. Lift the NAE55 off the DIN rails.
Enclosure Mount
To mount the NAE55 in an enclosure:
1. Mount the enclosure per the manufacturer’s
instructions.
2. Mount the NAE55 in the enclosure following the
guidelines in the Location Considerations and
Mounting the NAE55 sections of this document.
Note: MS-NIE55xx-x models (NIE55s) do not have FC
Bus terminal blocks or LONWORKS® network
terminal blocks.
The FC bus connections are optically isolated RS-485
ports with keyed 4-position terminal blocks that
communicate at 9.6k, 19.2k, 38.4k, or 76.8k baud. Use
an FC Bus port to integrate an N2 network or a BACnet®
Master-Slave/Token-Passing (MS/TP) FC Bus trunk into
the Metasys system.
Note: N2 and BACnet MS/TP Buses have different
protocols and network requirements. Do not
connect N2 and MS/TP devices to the same FC
Bus port.
The Shield (SHD) connections on the FC terminal blocks
are not connected to any earth ground connection. The
FC A and FC B terminal blocks are not interchangeable.
LONWORKS Network Terminal Block
The LONWORKS TP/FT-10 network connection on the
MS-NAE552x-2 models (only) is a 3-wire removable,
keyed terminal block. The SHD connection on the
LONWORKS network terminal block is an isolated terminal
and is not connected in the NAE552x. Use the LONWORKS
terminal block to connect LONWORKS networks to the
NAE552x.
4NAE55/NIE55 Installation Instructions
Computer Serial Ports
The RS-232-C serial ports on the NAE55 are for direct
connection using a standard 9-pin female Data Terminal
Equipment (DTE) to 9-pin female DTE null modem cable.
The NAE55 serial ports do not support external modems.
The RS-232-C serial ports are labeled RS232C A and
RS232C B (Figure 1).
Use the RS232C A port to connect directly to a computer
serial port to browse to the NAE55. Use this port only for
establishing a Point-to-Point Protocol (PPP) network
connection. Refer to the Metasys System Extended
Architecture Direct Connection and Dial-Up Connection
Application Note (LIT-1201639).
Important: Do not apply 24 VAC power to the NAE55
before installing the data protection battery.
See the Installing the Data Protection
Battery section in this document.
Important: Use copper conductors only. Make all wiring
in accordance with local, national, and
regional regulations.
Important: The NAE55 is a low-voltage (<30 VAC)
device. Do not exceed the NAE electrical
ratings. Applying high voltage to the NAE
may result in permanent damage to the NAE
and void any warranties.
Use the RS232C B port to connect with a VT100 terminal
or computer using a VT100 terminal emulator because
the RS232C B port outputs the device IP address. Use
this port only to obtain the NAE55 IP address at startup.
Refer to the NAE Commissioning Guide (LIT-1201519).
Universal Serial Bus (USB) Ports
The two USB ports labeled USB A and USB B are both
configured as masters and are independent of each other.
Use the USB A port to connect an optional external
modem. Refer to the NAE Commissioning Guide
(LIT-1201519) for more information on external modems.
Ethernet Port
The Ethernet port, labeled ETHERNET, is an 8-pin RJ-45
network port for connecting the NAE55 to Ethernet
networks. NAE55 engines can connect to Ethernet
networks at 10 Mbps, 100 Mbps, or 1 Gbps.
On MS-NIE55xx-x models, use the Ethernet port for
migration of N1 communications. Refer to the N1
Migration with the NIE Technical Bulletin (LIT-1201535).
Optional Internal Modem
MS-NAE55x1-x and MS-NIE55x1-x models have an
internal modem and a 6-pin RJ-12 modular jack labeled
MODEM. Connect a standard phone line plug and cable
to the to use the internal modem.
For information on commissioning an internal modem,
refer to the NAE Commissioning Guide (LIT-1201519).
Wiring the NAE55/NIE55
Mount the NAE55 securely before wiring it. Follow these
guidelines when wiring the NAE55:
Important: Do not apply 24 VAC power to the NAE
before completing and checking
connections. Short circuits or improperly
connected wires may result in permanent
damage to the equipment.
Important: Do not remove the terminal block keys. The
terminal block plugs and the terminal
sockets are keyed to fit together in the
correct configuration only.
Important: Prevent any static electric discharge to the
NAE. Static electric discharge can damage
the NAE and void any warranties.
• Route the supply power wires and communication
cables at least 50 mm (2 in.) away from the vent slots
in the sides of the NAE55 housing.
• Provide slack in the wires and cables. Keep cables
routed neatly around the NAE55 to promote good
ventilation, LED visibility, and ease of service.
Note: Ensure that the building automation network wiring
meets the specifications, rules, and guidelines in
the Wiring Considerations and Guidelines for
Network Integrations section.
To wire the NAE55:
1. Connect the Ethernet cable to the RJ-45, 8-pin
Ethernet port shown in Figure 1.
2. Connect the Building Automation System (BAS)
network cables to the appropriate ports.
• For N2 or MS/TP networks, connect the 3-wire
bus cable to one of the removable 4-terminal plugs
labeled FA A or FC B (Figure 5).
• For LONWORKS compatible networks, connect the
2-wire cable from the LONWORKS network trunk to
th removable 3-terminal plug labeled LON (Figure
6).
Note: If an N2 Bus or MS/TP Bus is connected
to the NAE55, you must set the NAE55
EOL switches to the proper positions. See
the Setting the End-of-the-Line Switches
section.
5NAE55/NIE55 Installation Instructions
3. If using a modem, connect a telephone line to the
modem port or connect an external modem to the
USB A as necessary.
Figure 5: FC Bus Terminal Block and Wiring
Connections
Figure 6: LONWORKS Network Terminal Block
and Wiring Connections
Figure 7: 24 VAC Supply Power Wiring
4. Make connections to the RS-232 serial ports (if
necessary).
5. Connect the 24 VAC supply power wires from the
transformer to the removable power terminal block
plug (Figure 7).
Power supply wire colors may be different on transformers
not manufactured by Johnson Controls. Follow the
transformer manufacturer’s instructions and the project
installation drawings.
The 24 VAC power should be connected to all network
devices so transformer phasing is uniform across the
devices. Powering network devices with uniform 24 VAC
supply power phasing reduces noise, interference, and
ground loop problems.
The NAE55 does not require an earth ground connection.

Setup and Adjustments
Installing the Data Protection Battery
Important: Do not apply 24 VAC power to the NAE55
before installing the data protection battery.
To install the data protection battery:
1. Remove the battery from its packaging. Remove the
battery cover on the NAE55 to expose the battery
compartment (Figure 1).
2. Carefully plug the NAE55 battery connector from the
battery compartment into the connector on the battery
cable (Figure 9).
3. Place the battery into the compartment (Figure 9).
4. Slide one end of the battery strap into the hole on the
opposite side of the strap (Figure 9), and loop the
strap tightly around the battery to minimize battery
movement.
5. Replace the cover of the battery compartment.
6. Apply 24 VAC power to the NAE55 immediately.
Important: The data protection battery must
maintain a small residual charge. The
battery ships from the factory with a
small residual charge. You should
connect 24 VAC power to the NAE55
immediately after connecting the battery
to ensure that the battery does not
completely lose its charge, which may
damage the battery.
Note: The 24 VAC power to the NAE55 charges the
data protection battery. At initial startup, the
battery requires a charging period of at least
2 hours before it supports data protection if
power fails. Maximum protection (up to three
consecutive power failures without recharging
time) requires a 24-hour charging period.
Setting the End-of-the-Line Switches
The network devices at each end of an FC Bus segment
must be set as network terminated devices. The NAE55
has two EOL switches (one for each FC Bus) that enable
you to set the NAE55 as a network terminated device on
the bus.
To set an NAE55 as an FC Bus terminated device,
position the switch on the EOL switch block to the ON
position (Figure 8).
Figure 8: FC Bus EOL Switch in the Factory Default
ON (Up) Position
Note: The NAE55 is shipped with the EOL switches for
both FC Buses in the initial factory position, ON
(Figure 8). If the NAE55 is not a terminated device
on the FC Bus, reposition the switch on the EOL
switch block to the Off (down) position.
Set the EOL switches appropriately for the FC A and FC
B buses. The NAE55 follows the same rules as other
switch-terminating devices listed in the Setting
Terminations sections of the N2 Communications Bus
Technical Bulletin (LIT-636018) and the MS/TP
Communications Bus Technical Bulletin (LIT-12011034).
Powering on the NAE55
After applying 24 VAC power, the NAE55 requires
approximately 3 minutes to start up and become
operational. See the LED Test Sequence at Startup
section.
Startup is complete and the NAE55 is operational when
the (green) RUN LED is On steady and the (red) GEN
FAULT LED is Off. See Figure 10 for LED locations.
Disconnecting Power from the NAE55
Important: The data protection battery must be installed
and charged before disconnecting the 24
VAC supply power.
The 24 VAC supply power is disconnected from the
NAE55 by removing the terminal block plug from the
power terminal port on the NAE55 (Figure 7).
When the 24 VAC supply power to the NAE55 is
disconnected or lost, the NAE55 is nonoperational. The
POWER LED (Figure 10) remains On, and the data
protection battery continues to power the NAE55 for
approximately 1 to 3 minutes so that volatile data can be
backed up in nonvolatile memory. The POWER LED goes
Off when the data backup is completed.
9NAE55/NIE55 Installation Instructions
Figure 9: NAE55 and NAE55 Data Protection Battery
Troubleshooting
LED Status Indicators
The NAE55 has LEDs to indicate power and
communication status. See Figure 10 and Table 7.
LED Test Sequence at Startup
During startup, the NAE55 automatically initiates an LED
test to verify the operational status of the LEDs.
Immediately after connecting supply power, the following
LED lighting sequence occurs:
1. The NAE55 emits one short beep, indicating that the
BIOS startup was successful.
2. The PEER COM, RUN, and GENL FAULT LEDs turn
on, indicating that the Operating System (OS) is
booting up. For NAE55 models, the FC A and FC B
LEDs also turn on.
3. The PEER COM, RUN, GENL FAULT LEDs, and the
FC A and FC B LEDs (on NAE55 models) shut off.
The RUN LED flashes to indicate that the NAE55
software is loading.
4. The LEDs display the operational status of the
NAE55. When the RUN LED goes On Steady, the
operating system and Metasys application are running
and the NAE55 is ready.
The total time to start up the NAE55 depends on the size
of the database and can take several minutes.
Figure 10: NAE55 with LED Designations
System Re-Boot Switch
The System Re-Boot switch (Figure 1) forces a manual
restart of the NAE55 processor. All data changes made
to the system since the last time the NAE55 saved data
are lost on restart, including alarm, trend, and audit trail
data.
Note: Press the System Re-Boot switch only if the
NAE55 fails to respond and cannot be accessed
by any user device. Do not press the System
Re-Boot switch unless you have tried other
reasonable means to fix the problem.
