3PRODUCT OVERVIEW
3.1 Product Introduction
Industrial cellular router wienet LTE LR240/241 is designed for wireless communication in mobile
networks that make use of traditional cellular technologies. It can also be used as a simple LAN-to-
LAN router.
The primary purpose of this router is its use in the Category 4 (Cat.4) services on the cellular LTE
network. Cat.4 rated router is capable of achieving typical speeds in 4G coverage areas where the
network is enabled with 20 MHz of contiguous spectrum.
The peak downlink data rate for Category 4 is approximately 150 Mbps. In the uplink, LTE Category
4 provides a peak data rate of 50 Mbps. The router is equipped with two independently configurable
Ethernet ports, RS232 and RS485 serial ports and with one digital input together with one digital
output.
The router supports VPN tunnel creation using various protocols to ensure safe communications.
The router provides diagnostic functions which include automatic monitoring of the wireless and
wired connections, automatic restart in case of connection losses, and a hardware watchdog that
monitors the router status.
With open Linux platform and wide possibilities of programming customer SW applications in
Python, C/C++.
Examples of possible applications:
•Mobile office
•Security system
•Telematic
•Remote monitoring
•Vending and dispatcher machines

5MOUNTING AND REMOVAL
5.1 Mounting Recommendations
The router can be placed:
•on a flat surface,
•on a DIN rail EN 60715 with the metal DIN rail clip. See chapter 5.2 "DIN Rail Mounting", p.16.
For most applications with a built-in router within a switchboard, it is possible to recognize two
kinds of environments:
•a non-public, industry environment of low voltage with high interference,
•a public environment of low voltage and without high interference.
For both of these environments, it is possible to mount the router to a switchboard, after which
there is no need to have examination immunity or issues in connection with EMC according to
EN 61439-1:2011.
In compliance with the EN 61439-1:2011 specification, it is necessary to observe the following
assembly instructions for a router attached to a switchboard:
•For whip antennas it is recommended to observe a minimum distance of 6 cm from cables and
metal surfaces on every side in order to avoid interference. When using an external antenna
separate from the switchboard it is necessary to fit a lightning conductor.
•When mounting a router on sheet-steel we recommend using a cable antenna.
•For all cables, we recommend to bind the bunch, and for this we recommend:
– The length of the bunch (the combination of power supply and data cables) should be a
maximum 1.5 m. If the length of data cables exceeds 1.5 m or if the cable is leading towards the
switchboard, we recommend installing surge protectors.
– Data cables must not have a reticular tension of ~ 230 V/50 Hz or ~ 120 V/60 Hz.
•Sufficient space must be left between each connector for the handling of cables.
•To ensure the correct functioning of the router we recommend the use of an earth bonding
distribution frame for the grounding of the grounding screw, see chapter 6.4 "Power Supply",
p.20.
5.2 DIN Rail Mounting
The DIN rail clip is supplied with the router as standard accessories.
The DIN rail clip is suitable for a DIN rail according to EN 60715 standard only. The default position of
the clip is shown in Figure 11.
When mounting the wall mounting clip, tighten the screws with max. torque of 0.4 Nm.

5.3 Removing from the DIN rail
Push the router down lightly, so the bottom part of the DIN rail clip (hitched to the DIN rail) gets
out of the rail.
Pull out the bottom part of the router away from the DIN rail.

6HARDWARE FUNCTIONALITY
See chapter 3.6 "Hardware Overview", p. 11 for the product hardware overview. Table 5lists a short
description of the hardware, including the links to the chapters with a detailed description.
6.1 SIM Card Slots
Slots for two SIM cards are located on the right panel of the router under a metal cover. It is
necessary to insert an activated SIM card, to work properly. If the PIN is required for the SIM, enter it
in the router's web interface. The SIM cards may have different APNs (Access Point Names) adjusted.
The SIM card changing procedure is described below.
Type of SIM cards: micro-SIM (3FF) 15.0 × 12.0 × 0.76 mm.
Inserting the SIM card:
•Always disconnect the router from the power supply before handling the SIM card.
•Unscrew two screws on the SIM card cover and remove the cover.
•To remove an inserted SIM card, use the flat end of a spudger, or your fingernail, press the SIM
card slightly into its slot until you hear a click. After hearing this click, release the card, and it will
pop out of its slot.
•To insert a SIM card, push card into the slot until it clicks into place.
•Place back the cover and fix it by two screws.
Figure 13: SIM Cards Insertion
6.2 Cellular Antennas
Main (ANT) and diversity (DIV) antennas can be connected to the router using the SMA connectors
located on the front panel.
Do not run the router without connected cellular antenna connected to the main antenna
connectors as the energy from the transmission is effectively reflected by the open end and can
damage the equipment.
•Recommended tightening moment for screwing the antenna to the SMA connector is 0.9 Nm.
•The diversity antenna improves the radio capability of the router at low signal strength.

6.4 Power Supply
The pins of power supply are physically connected to the 6-pin terminal block panel socket located
on the left panel. The connection of power supply is shown in Figure 15 and described in Table 8.

Positive pole of DC supply voltage (+9 … +48 V DC)

PWR(-)
Negative pole of DC supply voltage
Required power supply voltage for the router is between +9 V and +48 V DC, see the connection
scheme on Figure 15. Protection against reversed polarity without signaling is built into the router.
For correct operation it is necessary that the power source is able to supply a peak current of 1 A.
Unit has to be supplied by a power supply specified as a Limited Power Source (LPS) or CEC/NEC
Class 2 source of supply.
The metal case of the router is not connected to the negative pole of the power supply (common
pole). If recommended for the installation environment, protect the router by grounding it properly
by the grounding screw on the right panel, see Figure 16.
