Overview
The ToughNet TN-4500A Series M12 managed Ethernet switches are
designed for industrial applications in harsh environments. The TN
series switches use M12 connectors to ensure tight, robust connections,
and guarantee reliable operation against environmental disturbances,
such as vibration and shock. The wide 24 to 110 VDC dual power inputs
increases the reliability of your communications.
The TN-4500A Series includes PoE, non-PoE, and fiber switches.
•TN-4516A non-PoE models: 12 Fast Ethernet M12 ports; 4 Gigabit
Ethernet ports.
•TN-4516A PoE models: 12 Fast Ethernet M12 ports with PoE
functionality; 4 Gigabit Ethernet ports with PoE functionality.
•TN-4516A fiber (ODC) models: 12 Fast Ethernet M12 ports with PoE
functionality; 2 Gigabit Ethernet ports with PoE functionality; 2
Gigabit Ethernet ports with a Q-ODC fiber connector.
•TN-4524A PoE models: 24 Fast Ethernet M12 ports, 16 with PoE
functionality.
•TN-4528A PoE models: 24 Fast Ethernet M12 ports, 16 with PoE
functionality; 4 Gigabit Ethernet ports with PoE functionality.
•TN-4528A fiber (ODC) models: 24 Fast Ethernet M12 ports, 16 with
PoE functionality; 2 Gigabit Ethernet ports with PoE functionality; 2
Gigabit Ethernet ports with a Q-ODC fiber connector.
The -40 to 75°C operating temperature and IP42-rated waterproof
enclosure allow deployment in harsh environments. The TN-4500A
Series Ethernet switches are compliant with mandatory sections of EN
50155, covering operating temperature, power input voltage, surge,
ESD, and vibration, as well as conformal coating and power insulation,
making the switches suitable for a variety of industrial applications.

Hardware Version Appearance
The appearance of different TN-4500A Series hardware versions may
not be similar. For example, the shape and positions of LEDs on the TN-
4516A hardware version 3.x are different from previous hardware
versions. Secondly, the trenches on the front side are removed for
hardware version 3.x. You can also refer to the device label to
differentiate different device hardware versions (Rev).

Panel/Wall Mounting
STEP 1: Mounting the TN-4500A to a wall requires 4 screws. Use the
ToughNet switch as a guide to mark the correct position 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 on the right.
Do not screw the screws in all the way—leave a space of about 2 mm to
allow room for sliding the ToughNet switch 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 inser
ting the screw through
one of the keyhole-shaped apertures of the ToughNet switch.
STEP 3: Once the screws are fixed in the wall, hang the ToughNet
switch on the 4 screws using the large opening of the keyhole-shaped
apertures, and then slide the switch downwards. Tighten the four
screws for added stability.

- 17 -
NOTE
To provide greater protection against vibration and shock, use
screws with
a shaft diameter between 6.0 mm and 7.0 mm,
and fix the ToughNet switch onto the wall directly
using the
large opening of the keyhole-shaped apertures.
NOTE
The TN-4500A Series switches have passed IP42 certification.
To achieve IP42 protection,
only use upright panel or wall
mounting
installation. Water sprayed at an angle of up to 15°
degrees from the vertical
will not damage the product (as
indicated in the following illustration).
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.

- 18 -
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your
Moxa switch. This device has UL 61010-2-201
approval. Use copper conductors only,
75°C, and tighten to 4.5
pound-inches. For use in pollution degree 2 environments.
ATTENTION
Safety First!
Observe all electrical codes dic
tating 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 Switch
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.

- 19 -
ATTENTION
To ground this product to earth, use a green and
yellow AWG
16 or higher grounding cable.
ATTENTION
This product is intended to be mounted to a well
-grounded
mounting surface such as a metal panel.
Connecting the Power Supplies
The ToughNet TN-4500A Series switches support dual power inputs—
power input 1 and power input 2. The M23 6-pin male connector on the
TN-4500A Series switches' front panel is used for the dual power
inputs.

Pin
Description
Usage
1 PWR1 / DC +
Connect “PWR1 Live / DC +” to the positive (+)
terminal when using a DC power source.
2 PWR1 / DC - Connect “PWR1 Neutral / DC -” to the negative
(-) terminal when using a DC power source.
3 Chassis Ground
Connect the “Chassis Ground” to the equipment
ground bus for DC inputs.
4 PWR2 / DC -
Connect “PWR2 Neutral / DC -” to the negative
(-) terminal when using a DC power source.
5 PWR2 / DC + Connect “PWR2 Live / DC +” to the positive (+)
terminal when using a DC power source.
STEP 1: Plug your power cord connector into the power input port of
the TN-4500A switch.
STEP 2: Screw the nut on your power cord connector into the power
input connector on the switch to ensure a tight connection.
ATTENTION
Before connecting the TN
-4500A Series to the power input,
make sure the power source voltage is stable.

- 20 -
ATTENTION
Do not power on
the TN-4500A Series before connecting the
M23 connector.
Connecting the Relay Outputs
Each TN-4500A Series switch has two sets of relay outputs—relay
output 1 and relay output 2. The M12 A-coded 5-pin male connector on
the TN-4500A Series’ front panel is used for the two relay outputs. Use
a power cord with an M12 A-coded 5-pin female connector to connect
the relay contacts. You can purchase an M12 power cable from Moxa;
the model number is CBL-M12 (FF5P)/OPEN-100 IP67.
Pinouts for the relay output port on the TN-4500A series
N.C.: Not connected
FAULT:
The two sets of relay contacts of the M12 A-coded 5-pin male connector
are used to detect user-configured events. The two wires attached to
the fault contacts form an open circuit when a user-configured event is
triggered. If a user-configured event does not occur, the fault circuit
remains closed.
Connecting the Data Lines
10/100BaseT(X) Ethernet Port Connection
The TN-4500A Series models have two types of Ethernet ports:
10/100BaseT(X) M12 D-coded 4-pin female connectors and
10/100/1000BaseT(X) M12 X-coded 8-pin female connectors. The ports
located on the TN-4500A Series front panel are used to connect to
Ethernet-enabled devices. Most users configure these ports for Auto
MDI/MDI-X mode, in which case the port’s pinouts are adjusted
automatically depending on the type of Ethernet cable used (straight-
through or cross-over), and the type of device (NIC-type or
HUB/Switch-type) connected to the port.
In what follows, we give pinouts for both MDI (NIC-type) ports and
MDI-X (HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.
