Mounting Instructions
DIN-rail Mounting
The aluminum DIN-rail attachment plate is already attached to the
product’s casing. To mount the device on to a DIN rail, make sure that
the stiff metal spring is facing upwards and follow these steps.
1.
Pull down the bottom slider of
the DIN-rail bracket located at
the back of the unit
2.
Insert the top of the DIN rail
into the slot just below the
upper hook of the DIN-rail
bracket.
3.
Latch the unit firmly on to the
DIN rail as shown in the
illustrations below.
4.
Push the slider back into place.
Wall Mounting (optional)
The device can be mounted on to a wall using a wall-mounting kit. The
optional wall-mounting kit should be purchased separately.
Follow these steps to mount the device on to a wall:
Step 1
Use four screws to fasten the wall
-
mounting brackets on the left panel
of the device.
Step 2
Use another four screws to mount
the
device on to a wall or in a
cabinet.

- 6 -
IMPORTANT!
The diameter of the screw heads
should be greater than 7 mm
and less than 14 mm; the diameter of the shafts should be less
than 3 mm. The length of the screws should be greater than 6
mm.
NOTE
•Test the screw head and shank size by inserting the screws
into one of the keyhole shaped apertures of the wall-
mounting plates before attaching the plate to the wall.
•
Do not drive the screws in all the way—leave a space of
about 2 mm to allow room for sliding the wall mount panel
between the wall and the screws.
Wiring Requirements
•Use separate paths to route wiring for power and devices. If power
wiring and device wiring paths must cross, make sure the wires are
perpendicular at the intersection point.
•You can use the type of signal transmitted through a wire to
determine which wires should be kept separate. The rule of thumb
is that wiring that shares similar electrical characteristics can be
bundled together.
•Keep input wiring and output wiring separate.
•When necessary, it is strongly advised that you label wiring to all
devices in the system.
NOTE
Do not run signal or communication wiring and power wiring in
the same wire conduit. To avoid interference, wires with
different signal characteristics should be routed separately.
Grounding Requirements
There is a grounding connector located on the top panel of the device.
Connect it to an appropriate grounded metal surface. Grounding and
wire routing help limit the effects of noise due to electromagnetic
interference (EMI).
Connecting the Power Supply
C
onnect the power jack (in the package)
to
the DC terminal block (located on the
top
panel), and then connect the power
adapt
er. It takes about 3 minutes for the
system to boot up. Once the system is
ready, the
Power LED will light up. Both
m
odels support dual power inputs for
redundancy.
Use wires with 12 to 26 AWG wire size to connect to V+, V-, and GND.

- 7 -
The wire size of the power input and the earthing conductor should be
the same. Remove 8 to 9 mm of the DC wires’ protective cover and use
a torque of 4.5lb-in/0.51Nm to connect the wire. The max. wire
temperature should not exceed 100°C. The terminal blocks do not
accommodate more than one conductor wire per clamping point.
WARNING
EXPLOSION HAZARD!
Do not disconnect equipment unless the power has been
removed or the area is known to be non-hazardous.
WARNING
•
This product is intended to be supplied by a UL Listed
power adapter or DC power source whose output meets
SELV/LPS. The power source must be rated 12 to 48 VDC,
minimum 1 A, and minimum TMA = 85°C.
•
The power adapter should be connected to a socket outlet
with an earthing connection.
If you need further
information or assistance, contact a Moxa
representative.
Wiring the I/Os
There are four digital inputs and four digital
outputs on the top panel. Refer to the figure
on the left for detailed pin definitions.
Use wires with 16 to 28 AWG wire size
to
connect to DI, DO, and GND.
The
exposed conductor wire
length should be
7
-8 mm and the max. wire temperature
should not exceed 100°C. The terminal blocks
do not accommodate more than one
conductor wire per clamping point.

Inserting the microSD Card
The device comes with a micro-SD slot for storage expansion. The
microSD slot is located at the lower part on the front panel. To install
the card, remove the screw and the protection cover to access the slot
and insert the microSD card into the slot.
You will hear a click when the card is in place. To remove the card,
push the card in before releasing it.
Connecting to the Console Port
The console port is an RS-232 port located on the top panel, and can be
connected to a 4-pin pin header cable. You can use this port for
debugging or firmware upgrade.
