Any modification and repairation is not allowed without the permission of the manufacturer. It all
causes the loss of product warranty.
Only a certified expert or the manufacturer is allowed to open the enclosure!
Caution!
By general the device is using DC mains. 9-24V DC mains electric shock (12..24V DC)
hazard inside the enclosure! DO NOT open the enclosure and DO NOT touch the PCB.
(Consumption: 1.9W during 2G/3G communication, 2.9W during 4G LTE communication)
The IP51 immunity protection will be effective only in case of under normal usage and
operation conditions with unharmed hardware conditions by using the device in the
provided enclosure/chassis.
Deliberate damage or occing casualty of the device means the loss of product warranty.
To ensure general safety, please follow the following guideline:
■ Keep the chassis area clear and dust-free during and after installation.
■ Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll
up your sleeves.
■ Do not perform any action that creates a hazard to people or makes the equipment unsafe.
Safety with Electricity
Follow this guideline when working on equipment powered by electricity.
■ Read all the warnings in Safety Warnings.
■ Locate the emergency power-off switch for your installation location. If an electrical accident
occurs, you can quickly turn off the power.
■ Disconnect all power before:
–Installing or removing a chassis
–Working near power supplies
■Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.

■ Do not work alone if hazardous conditions exist.
■ Never assume that power is disconnected from a circuit. Always check.
■ Never open the enclosure of the router’s internal power supply.
■ If an electrical accident occurs, proceed as follows:
–Use caution; do not become a victim yourself.
–Turn off power to the device.
–If possible, send another person to get medical aid. Otherwise, assess the victim’s
condition and then call for help.
–Determine if the person needs rescue breathing or external cardiac compressions; then
take appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It may occur if
electronic printed circuit cards are improperly handled and may cause complete or intermittent
failures. Always follow ESD prevention procedures when removing and replacing modules:
■ Ensure that the router chassis is electrically connected to earth ground.
■ Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip
to an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground.
To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
■ If no wrist strap is available, ground yourself by touching a metal part of the chassis.
1.4 Mounting, fastening
The edge of the bopla aluminum enclosure of the device can be fixed by optionally with an
AB800MKL fixation part to a C-rail. You can also mount the enclosure to wall, place into server rack
or similar fixation opportunity.
Please note that close metal parts, the cabinet metal material and the industrial conditions as the
usage of high rate power or other external gained radio frequency signals can cause radio signal
disturbance and could cause weak wireless signal at reception or data transmitting or could cause
less effective signal reception, weak wireless fidelity. In any of these, we recommend you to test
the wireless signal reception and quality and if it is necessary use external, magnetic mount antenna
which is leaded outside of the cabinet and placed onto the cabinet’s surface – to ensure enough
reception. You can use an external magnatic mount antenna is you want.

The router enclosure can be fix/mount to wall by a C-rail adapter
1.5 Cable connection
1. Ensure that the router is not under power voltage, therefore the power adapter cable is
removed from the POWER titled microfit connector (1) –or the adapter is not connecting to
the power network.
2. Mount a proper antenna (3G or LTE) to the primary (MAIN) SMA connector (7).
3. In case of 4G router two antenna connectors are available. For the stable LTE
communication mount another LTE antenna to the secondary SMA antenna connector
(8) also.
4. Insert an activated SIM card to the SIM slot (2) - the SIM chip surface must be look to
top and the cutted edge of the SIM must be look to the router –then push the SIM until it
will be fixed and closed (you will hear a soft click sound).
(In case of necessary of SIM removal you have to power off the router and push the SIM a
bit, while it will be released and can be removed).

5. Connect an UTP cable to the router’s Ethernet titled RJ45 port (6). During the
configuration the cable’s opposite connector must be connected to the PC’s Ethernet port.
(After the configuration connect it to the network- or industrial device’s RJ45 port.)
6. You can also configure the router through the micro-USB slot (4) by a microUSB-USB cable
of the PC connection.
7. If you have ordered the device with RS232/RS485 expansion, connect the RS485
meter to the RS485 port (10) to receive the data of the meter. You can connect external
device to the RS232 port (11).
