DIN-rail Mounting
The DIN-rail mounting kit is fixed to the back panel of the EDS device
when you take it out of the box. Mount the EDS device on corrosion-
free mounting rails that meet the EN 60715 standard.
Installation
STEP 1—Insert the upper lip of
the DIN r
ail into the DIN-rail
mounting kit
.
STEP 2
—Press the EDS device
towards the
DIN rail until it
snaps into place.
Removal
STEP 1
—
Pull down the latch on
the mounting kit with a
screwdriver.
STEP 2
& 3—Slightly pull the
EDS device forward and lift up
to remove it from the DIN rail.
NOTE
Our DIN rail
kit
now utilizes a quick release mechanism to make
it easier for users to remove the DIN rail from the EDS device.

Wall Mounting (Optional)
For some applications, you will find it convenient to mount the Moxa
EDS device on a wall, as shown in the following illustrations:
STEP 1—Remove the DIN-rail
attachment pl
ate from the rear
panel of the EDS device,
as
illustrated
in the diagram on
the
right.
STEP 2—Mounting the EDS device on a wall
requires
six screws. Use the EDS device, with wall
mount plates attached, as a guide to mark the
correct locations of the
six screws. T
he heads of the
screws should be less than 6.0 mm in diameter,
and the shafts should be less than 3.5
mm in
diameter, as shown in the figure on at right.
NOTE
Before tightening the screws into the wall, make sure the screw
head and shank size are suitable by inserting the screw through
one of the keyhole
-shaped apertures of the Wall Mounting
Plates.
NOTE
Do not screw the screws in all the way—leave about 2 mm to
allow room for sliding the wall mount panel between the wall
and the screws.
STEP 3—Once the screws are
fixed
to the wall, insert the
four screw heads through the
wide parts of the keyhole
-
shaped apertures, and then
slide
the EDS device
downwards, as indicated
in
the figure
at the right.
Tighten the four screws for
more
stability.

Wiring Requirements
ATTENTION
Safety First!
External metal parts are hot. Take
the necessary precautions if
you are required to handle the device.
ATTENTION
In order to ensure reliable operations, please make sure the
operating temperature of the environment does not exceed the
specifications. When mounting an EDS device with other
operating units in a cabinet without forced ventilation, a
minimum of
4 cm spac
e on both the left and right of the switch
is recommended.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your EDS device. Calculate the maximum possible
current in each
power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for
each wire size. If the current goes above the maximum ratings,
the wiring could overheat, causing serious damage to your
equipment.
Be sure to read and follow these important points below:
•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.
NOTE
Do not run signal or communications wiring and power wiring
through the same wire conduit. To avoid interference, wires
with different signal characteristics should be routed separately.
•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.
•You should separate input wiring from output wiring.
•We advise that you label the wiring to all devices in your system.

Grounding the Moxa EDS Series
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from
the ground screw to the grounding surface prior to connecting devices.
ATTENTION
This product is intended to be mounted to a well
-grounded
mounting surface such as a metal panel.
Suggested Wire Type for Wiring Relay Contact
(RELAY), Digital Input (DI), and Power Inputs
(P1/P2)
The EDS device includes two 4-pins 3.5 mm pin-pitch terminal blocks.
When wiring the relay contact (RELAY), digital input (DI), and power
inputs (P1/P2), we suggest using the cable type AWG 18-24 and the
corresponding pin type cable terminals.
NOTE
The wire must be
able to withstand at least 105°C and the
torque value should be 4.5 lb-in (0.51 N-m).
NOTE
W
e suggest the length of the pin type cable terminal is 8 mm.
I
n order to tighten the wire properly, ①use a small flathead
screwdriver to press the push
-
in button beside each terminal of
the terminal block connector before and during
②
inserting the
wire.
③Release the screwdriver after the wire has been fully
insert
ed. Please refer to the diagram below.
Wiring the Relay Contact
The EDS device has one set of relay output. This relay contact uses two
contacts of the terminal block on the EDS’s power module. Refer to the
section for detailed instructions on how to connect the wires to the
terminal block connector, and how to attach the terminal block
connector to the terminal block receptor.

- 8 -
Relay:
The two contacts of
the 4-pin terminal
block connector are used to detect
user
-configured events. The two wires
att
ached to the fault contacts form an
open circui
t when a user-configured
event is triggered or
there is no power
supply to the switch
. If a user-
configured event does not occur, the
fault circuit remains closed.
Wiring the Redundant Power Inputs
The EDS device includes both high-voltage and low-voltage products.
For the low-voltage (LV models) products, there are two power inputs
for redundancy; for the high-voltage (HV models) products, there is
only one power input. Refer to the instructions and diagram below on
how to connect the wires to the terminal block connector on the
receptor.
STEP 1: Insert the Positive/Negative
DC or Line/Neutral AC wires into the
V+/V
- or L/N terminals, respectively.
STEP 2:
To keep the DC or AC wires
from pulling l
oose, use a small flat-
blade screwdriver to tighten the wire
-
clamp screws on the front of the
terminal block connector.
STEP 3:
Insert the plastic terminal
block connector prongs into the
terminal block receptor, which is
located on the EDS devices’ right side.

- 9 -
Wiring the Digital Inputs
The EDS device has one set of digital input (DI). The DI consists of two
contacts of the 4-pin terminal block connector on the EDS's right-side
panel. Refer to the instructions and diagram below on how to connect
the wires to the terminal block connector on the receptor.
STEP 1:
Insert the negative
(ground)/positive DI wires into the
┴
/I terminals, respectively.
STEP 2:
To keep the DI wires from
pulling loose, use a small flat
-blade
screwdriver to tighten the wire
-clamp
button
on the front of the terminal
block connector.
STEP 3:
Insert the plastic terminal
block connector prongs into the
terminal block receptor, which is
located on the EDS devices’ right side.
Rotating the Power Module
The power module for the EDS device can be rotated to make it easier
to fit your field site application.
Step 1:
Remove the two screws that fasten the power module to the
EDS device
and remove the module.
Step 2:
Turn the power module clockwise so that the power, digital
input
, and relay output connectors can be moved upwards.
Step 3:
Replace the module back
on to the EDS device.
Step 4:
Fasten two screws on to the module.

Communication Connections
Each EDS-4012 Series switch has various types of communication
ports:
•RJ45 console port (RS-232 interface)
•USB storage port (type A connector, currently disabled)
•10/100BaseT(X) Ethernet ports
•10/100/1000BaseT(X) or 100/1000BaseSFP combo ports
•100/1000BaseSFP slots
•microSD card slot (currently disabled)
Console Port Connection
The EDS device has one RJ45 console port (RS-232), located on the
front panel. Use either an RJ45-to-DB9 (see the cable following wiring
diagrams) to connect the EDS’s console port to your PC’s COM port.
You may then use a console terminal program, such as Moxa PComm
Terminal Emulator, to access the EDS that has a baud rate of 115200.

NOTE
The USB function is currently reserved and may be required in

charging any devices.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the front panel of the switch are
used to connect to Ethernet-enabled devices. Most users will choose to
configure these ports for Auto MDI/MDI-X mode, in which case the
port’s pinouts are adjusted automatically depending on the type of
Ethernet cable used (straight-through or cross-over), and the type of
device (NIC-type or HUB/Switch-type) that is connected to the port.
In the following, we give pinouts for both MDI (NIC-type) ports and
MDI-X (HUB/Switch-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.
