DIN-Rail Mounting
Install the unit in a standard DIN rail. Recess the unit to allow at least 2” of horizontal clearance for CAT5e
cable bend radius.
To install the plastic clip units to 35mm
industrial DIN rail, place the top edge of the
included mounting bracket on the back of the
unit against the DIN rail at a 15° angle as shown.
Rotate the bottom of the unit to the back (away
from you) until it snaps into place.
To remove the plastic clip units from the
35mm industrial DIN rail, place a flat head
screwdriver into the release clip found at the
bottom of the unit, and apply downward force on
the clip until it disengages from the bottom of the
unit from the DIN rail. Rotate the bottom of the
unit towards you and up at an approximate 15°
upward angle to completely remove the unit.
To install the metal clip units to 35mm
industrial DIN rail, place the top edge of the
included mounting bracket on the back of the
unit against the DIN rail at a 15° angle as shown.
Rotate the bottom of the unit to the back (away
from you) until it snaps into place.
To remove the metal clip units from the 35mm
industrial DIN rail, pull forward on the unit until
it disengages from the bottom of the DIN rail.
Rotate the bottom of the unit towards you and up
at an approximate 15° upward angle to
completely remove the unit.

URMK 1000-PM
Most N-Tron™ products are designed to be mounted on industry standard 35mm DIN rail. However, DIN rail
mounting may not be suitable for all applications. Our Universal Rack Mount Kit (P/N: URMK) may be used to
mount the 100 Series enclosures to standard 19" racks, and our Panel Mount Assembly (P/N: 1000-PM) may be
used to mount the metal clip versions of the 100 Series enclosures to a panel or any other flat surface. NOTE:
the 1000-PM will only work with the factory installed –MDR metal clip options and it is not acceptable for the
116TX units.

N-TRON SWITCH GROUNDING TECHNIQUES FOR 100 SERIES
The grounding philosophy of any control system is an integral
part of the design. N-Tron switches are designed to be grounded,
but the user has been given the flexibility to float the switch
when required. The best noise immunity and emissions (i.e. CE)
are obtained when the N-Tron switch chassis is connected to
earth ground via a drain wire. Some N-Tron switches have metal
din-rail brackets that can ground the switch if the din-rail is
grounded. In some cases, N-Tron switches with metal brackets
can be supplied with optional plastic brackets if isolation is
required.
Users may run a drain wire & lug from the screw provided on the
back face of the enclosure. In the event the provided grounding
screw has been lost, care should be taken to limit the penetration
of the outer skin by less than 1/4". Failure to do so may cause
irreversible damage to the internal components of the switch.
Note: Ensure the power supply is grounded properly before
applying power to the grounded switch. This may be verified by
using a voltmeter to determine that there is no voltage difference
between the power supply’s negative output terminal and the
chassis grounding point of the switch.
As an alternative grounding method, both V- legs of the
power input connector are connected to chassis internally on
the PCB. Connecting a drain wire to earth ground from one
of the V- terminal plugs as shown here will ground the
switch and the chassis. The power leads from the power
source should be limited to 3 meters or less in length.
If the use of shielded cables is required, it is generally
recommended to only connect the shield at one end to
prevent ground loops and interfere with low level signals
(i.e. thermocouples, RTD, etc.). Cat5e cables manufactured
to EIA-568A or 568B specifications are required for use
with N-Tron Switches.

In the event all Cat5e patch cable distances are small (i.e. All Ethernet devices are located the same local
cabinet and/or referenced to the same earth ground), it is permissible to use fully shielded cables terminated to
chassis ground at both ends in systems void of low level analog signals.

CONNECTING THE UNIT
For FX/FXE units, remove the dust cap from the fiber optic connectors and connect the fiber optic cables.
The TX port (located on the bottom connector) on the FX/FXE models should be connected to the RX port of the far
end station. The RX port (located on the top connector) on the FX/FXE versions should be connected to the TX port
of the far end station.
For 10Base-T ports, plug a Category 3 (or greater) twisted pair cable into the RJ45 connector. For
100Base-T ports, plug a Category 5 (or greater) twisted pair cable into the RJ45 connector. Connect the
other end to the far end station. Verify that the LNK LED’s are ON once the connection has been
completed. To connect any other port to another Switch or Repeater, use a standard Cat5 straight through or
crossover cable.
Warning: Creating a port to port connection on the same switch (i.e. loop) is an illegal operation and will
create a broadcast storm which will crash the network!
TROUBLESHOOTING
1. Make sure the (Power LED) is ON.
2. Make sure you are supplying sufficient current for the version chosen. Note: The Inrush current will
exceed the steady state current by ~ 2X.
3. Verify that Link LED’s are ON for connected ports.
4. Verify cabling used between stations.
5. Verify that cabling is Category 3 or greater for 10Mbit Operation.
