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.

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.

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.
