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 NAE-S wall
mount feet or housing.
DIN Rail Mount Applications
To mount the network engine on DIN rails, we highly
recommend a horizontal position. Follow these steps:
1. Mount two DIN rails horizontally, so they are 125 mm
(4.9 in.) apart on centers (Figure 3). We recommend
that you
do not
mount the unit vertically on DIN rails.
2. Snap the DIN clips on the bottom of the NAE-S to the
outward position.
3. Hang the NAE-S on the DIN rail hooks on the back of
the unit.
4. Press the DIN clips back into position to secure the
unit on the DIN rails.

Mount Applications
To remove the network engine from the DIN rails, follow
these steps:
1. Snap the DIN clips on the bottom of the NAE-S to the
outward position.
2. Lift the NAE-S off the DIN rails.
Wiring
Power Supplies, Network, and
Communication Connections
See Figure 2 for the location of the power supply
terminals, network communication terminals, and
Ethernet jack. One power supply terminal is for the NAE-S
and the other for the encryption board.
Power Supplies
Important:
Install the data protection battery before
applying 24 VAC power to the NAE-S. See
.
For the United States and Canada, use a Class 2, 24 VAC
power supply with a 50 VA minimum output. See the
Use a dedicated power supply to the NAE-S only. Do not
connect any other loads to the power supply. Additional
loads may cause noise interference.
The encryption board requires a separate dedicated 24
VDC power supply provided by the DeltaPSU CliQ (Rev04)
power supply system. The power supply requires 120 VAC
power to provide a 24 VDC output that plugs directly into a
port on the front of the NAE-S.
FC Bus Terminal Block
The two FCs Bus connections on the NAE-S models are
removable, keyed terminal blocks labeled
FC A
and
FC B
.
The FC bus connections are optically isolated RS-485 ports
with keyed 4-position terminal blocks that communicate at
9600, 19,200, 38,400, or 76,800 baud. Use an FC Bus port to
integrate an N2 network or a BACnet
®
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.
Computer Serial Port
The
RS232C-B
port on the NAE-S (Figure 2) is for direct
connection using a standard 9-pin female DTE to 9-pin
female DTE null modem cable. The NAE-S serial port does
not support external modems. The port is accessible only
when the network engine cover is removed. Also, the
serial port is no longer functional for
Metasys
Release 10.0
or later.
Use the hidden
RS232C-B
port to connect with a VT100
terminal or computer using a VT100 terminal emulator.
During device startup, the
RS232C-B
port outputs the
device's IPv4 address. Use this port only to obtain the
network engine IPv4 address at startup. The port does not
accept input during normal operation. Refer to the
NAE
Commissioning Guide (LIT-1201519)
for more details.
Ethernet Port
The Ethernet port, labeled
ETHERNET
, is an 8-pin RJ-45
network port for connecting the NAE-S to Ethernet
IP networks. NAE-S engines can connect to Ethernet
networks at 10/100/1000 Mbps.
Wiring the NAE-S
Mount the NAE-S network engine securely before wiring it.
Follow these guidelines when wiring the unit:
CAUTION
Risk of Electric Shock.
Disconnect the power supply before making electrical
connections to avoid electric shock.
