2.9 Antenna Installation
Rotate the antenna into the antenna connector accordingly.
The external cellular antenna should be installed vertically always on a site with a good cellular signal.
Note: UR51 router supports dual antennas with “Main” and “AUX” connectors. “Main” interface is for
data receiving and transmission. “AUX” interface is for enhancing signal strength, which cannot be used
separately.
2.10 Mounting the Router
The router can be placed on a desktop or mounted to a wall or a DIN rail.
2.10.1 Wall Mounting (Measured in mm)
Use 2 pcs of M3×6 flat head Phillips screws to fix the wall mounting kit to the router, and then use 2 pcs of
M3 drywall screws to mount the router associated with the wall mounting kit on the wall.
Recommended torque for mounting is 1.0 N. m, and the maximum allowed is 1.2 N.m.

UR51 User Guide
18
2.10.2 DIN Rail Mounting (Measured in mm)
Use 2 pcs of M3×6 flat head Phillips screws to fix the DIN rail to the router, and then hang the DIN rail on
the mounting bracket. It is necessary to choose a standard bracket.
Recommended torque for mounting is 1.0 N. m, and the maximum allowed is 1.2 N.m.
2.11 Connect the Router to a Computer
2.12 Installation of Power Supply and Protective Grounding
2.12.1 Power Supply Installation
A. Take out the terminal from the router and unscrew the bolt on terminal.
B. Screw down the bolt after inserting power cable into the terminal.
Connecting the Power Cable
If you insert wires into the reverse holes, the router will not start and you must switch the wires

2.12.2 Protective Grounding Installation
1. Remove the grounding nut.
2. Connect the grounding ring of the cabinet’s grounding wire onto the grounding stud and screw up
the grounding nut.
The router must be grounded when deployed. According to operating environment, the ground
wire should be connected with grounding stud of router.
2.13 Examine
1. Double check antenna connection.
2. Double check if SIM card is inserted and become available.
3. Power on the UR51 wireless cellular router and check indicators status.
(1) If Status LED blinks slowly, the system is running properly.
(2) If SIM1 or SIM2 indicator is static green, the router is connected to network already.
