Before the installation, ensure the following:
Sufficient space has been reserved for the router.
The DIN rail has been fixed.
Pull the fixture on the DIN rail mounting
kit at the back of the router.
1
Place the DIN rail mounting kit onto
the DIN rail and press the fixture to
secure the router on the DIN rail.

Scenario 1: Installing the Router on a DIN Rail
Fixture
Scenario 2: Mounting the Router on a Wall
Mark the positions of two mounting
holes on the wall.
1
Installation Method 1
Drill holes for ST4.2 tapping screws on
the wall using a hammer drill with an
appropriate drill bit.
2
The methods for installing, connoting and logging in to the AR-Sc, AR-Se, AR-Sa, AR-So
series routers and AR-PM series UPS are similar. AR-Sc-Lc-MC is used as an example here.
AR-PM series UPS cannot be mounted on a Wall.

Hang the router on the tapping
screw through the pre-mounting
hole at the back. Hold the bottom
of the router and use another ST4.2
tapping screw to secure the router
on the wall.

Connecting the Router
WARNING To avoid electric shock, do not connect power cables while the power is on.
Do not power on the router before you finish connecting and arranging cables.
An LTE remote antenna is delivered with the router. Connect it to the LTE MAIN
interface of the router.
For other interfaces, make cables onsite using self-provided terminals. The following
tables provide pin assignments of different interfaces.
The FXS interface cannot connect to a PSTN network and is only used for internal.
