Important Notice
This device, like any wireless device, operates using radio signals which cannot guarantee the transmission and
reception of data in all conditions. While the delay or loss of signal is rare, you should not rely solely on any
wireless device for emergency communications or otherwise use the device in situations where the interruption of
data connectivity could lead to death, personal injury, property damage, data loss, or other loss. NetComm
Wireless accepts no responsibility for any loss or damage resulting from errors or delays in transmission or
reception, or the failure of the NetComm Wireless NWL-25 to transmit or receive such data.
Safety and Hazards
Warning –Do not connect or disconnect cables or devices to or from the USB port, SIM card tray, Ethernet port or the terminals of the
Molex power connector in hazardous locations such as those in which flammable gases or vapours may be present, but normally are
confined within closed systems; are prevented from accumulating by adequate ventilation; or the location is adjacent to a location from
which ignitable concentrations might occasionally be communicated.

Placement of the router
The two external high-performance antennas supplied with the router are designed to provide optimum signal
strength in a wide range of environments. If you find the signal strength is weak, try adjusting the orientation of the
antennas. If you are unable to get an acceptable signal, try moving the router to a different place or mounting it
differently.
Important –When selecting a location for the router, allow at least 20 seconds for the signal strength LEDs to update before trying a
different location.
Mounting options
The NWL-25 router can be quickly and easily mounted in a variety of locations.
Mounted flat against the wall
When mounted flat against the wall, the NWL-25 router has a slimline form factor. Use appropriately sized screws in
the mounting holes provided on the base of the unit.
Figure 4 - Wall mount - Flat against the wall
Perpendicular to the wall
If a large surface area is not available, there is the option of mounting the router perpendicular to the wall. This
gives the router a small wall footprint while remaining securely attached. Use appropriately sized screws in the
mounting holes provided on the back of the unit.

C Section DIN Rail mount
The NWL-25 router easily slides onto a C Section DIN rail so that it is horizontally mounted. The DIN Rail mounting
bracket is not required for C Section DIN rail mounting.
Figure 6 - C Section DIN rail mount
To mount the unit on a C-Section DIN rail, slide it on as illustrated below:
Figure 7 - Mounting the unit on a DIN rail
Mounting bracket
The provided mounting bracket provides additional methods of mounting the NWL-25 router.
To attach the mounting bracket, slide it onto the rear of the router as shown in the diagram below:

To remove the bracket, press the PUSH button and slide the router off the bracket:
Figure 9 - Removing the mounting bracket
Using the mounting bracket for wall mounting
By first attaching the DIN rail bracket to the wall, the NWL-25 router can be easily attached and removed from the
bracket.

Using the mounting bracket for Top hat DIN rail mounting
The NWL-25 router may be vertically mounted to the wall with the bracket by sliding the bracket onto a top hat
DIN rail
Figure 11 - Top hat DIN rail mount
Alternatively, you can attach it to the DIN Rail by using the V bend in the bracket as illustrated below:
Figure 12 - Attaching the mounting bracket to the DIN rail using the V bend
Desk mount
In situations where wall mounts and DIN rails are not required, you can simply place the NWL-25 router on a desk
using its rubber feet to prevent it from slipping.

Powering the router
The NWL-25 router can be powered in one of two ways:
1DC power input via 6-pin connector (8-40V DC)
2DC power input via field terminated power source (8-40V DC)
The green power LED on the router lights up when a power source is connected.
DC power via 6-pin connector
The DC input jack can accept power from a separately sold DC power supply. Both a standard temperature range
DC power supply and an extended temperature range DC power supply are available to purchase as accessories.
To power the device via DC Power via the 6-pin connector, remove the attached green terminal block from your
router and connect the external DC power supply to the router’s green DC power jack.
DC power via field terminated power source
If an existing 8-40V DC power supply is available, you can insert the wires into the supplied terminal block to power
your router. Use a flathead screwdriver to tighten the terminal block screws and secure the power wires, making
sure the polarity of the wires are correctly matched, as illustrated below.

Viewing power source information
You can view the current power input mode in the Advanced status section of the device’s web user interface. This
is useful for remotely monitoring the device. You can also use the Software Development Kit to access this
information for advanced purposes.
To view the router’s power source information, log in to the router and expand the Advanced status box on the
status page. See the Status section of this manual for more information on the status page.
Installing the router
After you have mounted the router and connected a power source, follow these steps to complete the installation
process.
1Connect equipment that requires network access to the Ethernet port of your router. This may be your
computer for advanced configuration purposes, or your end equipment which requires data access via the
NWL-25 router. You can connect one device directly, or several devices using a network switch.
2Ensure the external power source is switched on and wait 2 minutes for your NWL-25 router to start up. To
check the status of your router, compare the LED indicators on the device with those listed in the LED
Indicators section of this guide.
