702-W DIN RAIL MOUNTING
Install the unit on a standard 35mm Din-Rail. Recess the 702-W unit to allow at least 3” of horizontal
clearance for copper cable bend radius.
DIN-Rail Mounting
To mount the unit to the 35mm DIN-Rail, place
the top edge of the bracket on the back of the
unit against the DIN-Rail's top edge at an upward
angle. Then, rotate the unit downward and back
against the DIN-Rail until it snaps into place.
You may need to adjust the angle of the antennas
depending on the amount of clearance available.
To remove the vertically mounted unit from
35mm DIN-Rail, carefully apply downward
pressure on the unit. Then, rotate the unit
upward and away from the 35mm DIN-Rail and
lift up for removal.
19” Universal Rack Mounting
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 702-
W to standard 19" racks as an option.

APPLYING POWER (702-W Side View)
Unscrew & Remove the DC Voltage Input Plug from the Power Input Header
Install the DC Power Cables into the Plug (observing polarity).
Plug the Voltage Input Plug back into the Power Input Header.
Tightening torque for the terminal block power plug is 0.5 Nm/0.368 Pound Foot.
Verify the Power LED stays ON (GREEN).
Notes:
Only 1 power supply must be connected to power for minimal operation. For redundant power
operation, V1and V2inputs must be connected to separate DC Voltage sources. This device will
draw current from both sources simultaneously. Use 16-28 gauge wire when connecting to the
power supply.
The LAN port supports Power over Ethernet and can be used redundantly with the power input
mentioned above.
Recommended 24V DC Power Supplies, similar to: N-Tron’s P/N NTPS-24-1.3:
Input AC 115/230V
Output DC 24-28V
Output Current 1.3A @ 24V

M12 Power Cable Assembly
1. Cut the shielded power cable to the desired / required length. The power cable should be a shielded cable with an outer
jacket diameter of 6 to 8mm in size. The individual wires inside the cable must be between 18-24awg (stranded). The
cable must be UL recognized for use up to 110°C.
2. Using the picture below as a guide, slide the parts together in the order shown.

(Revised 2013-23-10) Page 13 of 62
3. Strip back and tin the five wires (red, black, white, green and drain wire – Note: these colors are just an example, actual
colors may vary). Cut off the water block paper and the flat EMI shield (this looks like aluminum foil). Be sure to keep
the drain wire.
4. Screw the wires into the proper assignment by following the chart below (NOTE: the colors used in this example are just
an example, actual wire colors may vary):
5. Screw the header end onto the plastic threaded sleeve (looks like a round pipe).
6. Push and screw down the pressure screw into the other end of the plastic threaded sleeve (this will compress the rubber
gasket giving you an IP67 seal on the cable’s jacket). Note: in order to make a good seal, the outer cable diameter must
be between 6-8mm and the outer jacket must be waterproof – Some plastic jackets will absorb water and are not
waterproof.

Connecting the Unit
For the 10/100 Base-TX port, plug a Category 5E twisted pair cable into the RJ45 connector. Connect the
other end to the far end station. Verify that the LNK/ACT LED is ON once the connection has been
completed. Use a standard Category 5E straight through or crossover cable with a minimum length of one
meter and a maximum length of 100
meters.
N-Tron recommends the use of pre-
manufactured Cat5E cables to ensure the
best performance. If this is not an option
and users must terminate their own ends
on the Cat5E cables; one of the two color
coded standards shown to the right should
be utilized. If a user does not follow one
of these two color code standards then the
performance and maximum cable distance
will be reduced significantly, and may
prevent the unit from establishing a link.
RJ45 CONNECTOR CRIMP SPECIFICATIONS
Please reference the illustration below for your Cat5 cable specifications:

N-Tron SWITCH GROUNDING TECHNIQUES
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 devices with metal brackets can be supplied with
optional plastic brackets if isolation is required.
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.
Alternatively, users can run a drain wire & lug from any of the
Din-Rail screws or empty PEM nuts on the enclosure. When
using an unused PEM nut to connect a ground lug via a machine
screw, care should be taken to limit the penetration of the outer
skin by less than 1/4 in. Failure to do so may cause irreversible
damage to the internal components of the switch.
Note: Before applying power to the grounded switch, you must
use a volt meter to verify there is no voltage difference between
the power supply’s negative output terminal and the device
chassis grounding point.
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 devices.
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.
Drain wire with lug connecting switch chassis to known grounding point.
