Overview
The ToughNet TN-4900 Series is designed for rolling stock Ethernet
networks. These routers feature M12 interfaces to ensure tight, robust
connections, and guarantee reliable operation in industrial environments
where vibration and shock are commonplace. The TN-4900 Series routers
are equipped with 8 Gigabit ports and up to 4 bypass relay ports. In
addition, the PoE models in this Series have 4 IEEE 802.3at/af PoE Gigabit
ports while the 16-port models have 8 PoE-capable Fast Ethernet ports.
These routers also feature firewall, ETBN, routing functionality, and a
broad power input range of 24 to 110 VDC to facilitate different
applications across networks. The -40 to 70°C wide temperature range
allows the TN-4900 Series to operate in demanding environmental
conditions for extended periods of time. Furthermore, these routers are
compliant with the mandatory requirements of EN 50155, making them
suitable for a variety of industrial applications.

Panel/Wall Mounting
STEP 1: Mounting the TN-4900 to a wall requires 4 screws. Use the
ToughNet router as a guide to mark the correct positions of the 4 screws.
STEP 2: Use the 4 screws in the
panel mounting kit. If you would like
to use your own screws, make sure
the screw head
is
between 6.0 mm
and 7.0 mm
in diameter and the
shaft
is less than 4.0 mm in
diameter, as shown
at the right.
The torque value of the mounting
screws is 4.5 kgf-cm.
Do not screw the screws in all the way—leave a space of about 2 mm to
allow room for sliding the ToughNet router between the wall and the
screws.
NOTE
Before tightening the screws into the wall, make sure the screw
head and shaft size are suitable by inserting the screw through
one of the keyhole-shaped apertures of the ToughNet router.
STEP 3: Once the screws are fixed in the wall, hang the ToughNet router
on the 4 screws through the large opening of the keyhole-shaped
apertures, and then slide the router downwards. Tighten the four screws
for added stability.
NOTE
To provide greater protection from vibration and shock, use
screws with shaft diameter between 6.0 mm and 7.0 mm, and fix
the ToughNet
router onto the wall directly through the large
opening of the keyhole-shaped apertures.
Wiring Requirements
WARNING
Turn the power off before disconnecting modules or wires. The
correct power supply voltage is listed on the product label. Check
the voltage of your power source to make sure you are using the
correct voltage. Do NOT
use a voltage greater than what is
specified on the product label.
These devices must be supplied by a SELV source as defined in
the Low Voltage Directive 2006/95/EC and 2004/108/EC.

ATTENTION
Safety First!
Be sure to
disconnect the power cord before installing and/or
wiring your Moxa
router. This device has UL 61010-2-201
approval. Use copper conductors only,
70
°C, and tighten to 4.5
pound-inches. For use in pollution degree 2 environments.
ATTENTION
Safety First!
Observe all electrical codes dictating the
maximum current
allowable for each wire size. If the current
goes above the
maximum ratings, the wiring could overheat,
causing serious
damage to your equipment.
Please read and follow these guidelines:
•Use separate paths to route wiring for power and devices. If power
wiring and device wiring paths must cross, make sure the wires are
perpendicular at the intersection point.
NOTE: Do not run signal or communications wiring and power wiring
through the same wire conduit. To avoid interference, wires with
different signal characteristics should be routed separately.
•You can use the type of signal transmitted through a wire to
determine which wires should be kept separate. The rule of thumb is
that wiring that shares similar electrical characteristics can be
bundled together.
•Keep input wiring and output wiring separated.
•It is strongly advised that you label wiring for all devices in the system
when necessary.
Grounding the ToughNet Router
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
grounding screw to the grounding surface prior to connecting devices.
