DIN-Rail Mounting
The aluminum DIN-rail attachment plate should already be fixed to the
back panel of the EDS when you take it out of the box. If you need to
reattach the DIN-rail attachment plate, make sure the stiff metal spring is
situated towards the top, as shown in the figures below.
STEP 1: Insert the top of the
DIN
-rail into the slot just below
the stiff metal spring.
STEP 2: The DIN-rail attachment
unit will snap into place as shown
below.
To remove the DIN-rail from the EDS, simply reverse Steps 1 and 2.
Wall Mounting (optional)
For some applications, you will find it convenient to mount the EDS on the
wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN
-rail attachment plate
from the EDS’s rear panel,
and then attach the wall
mount plates,
as shown in
the
figure.
STEP 2:
Mounting
the EDS on the wall requires 4 screws. Use
the
s
witch, with wall mount plates attached, as a guide
to mark the correct locations of the 4 screws. The
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 at the right.
NOTE
Before tightening screws into the wall, make sure the screw head
and shank size are suitable by inserting the screw into one of the
keyhole-shaped apertures of the Wall Mounting Plates.
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 in the
wall, insert the four s
crew heads
through the large parts of the
keyhole
-
shaped apertures, and then
slide the EDS downwards, as
indicated. Tighten the four screws
for
added stability.

Wiring Requirements
WARNING
Safety First!
Turn
the power off before disconnecting modules or wires. The
proper
power supply voltage is listed on the product label. Check
the voltage of your power source to make sure you are using the
correct voltage. Do NOT use a voltage greater than
what is
specified on the product label.
These devices must be supplied by a
n AELV
source as defined in
the Low Voltage Directive 2006/95/EC and 2004/108/EC.
WARNING
Safety First!
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maxim
um current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could
overheat, causing serious damage to your equipment.

You should also pay attention to the following items:
•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
in 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 with similar electrical characteristics can be bundled
together.
•Keep input wiring and output wiring separated.
•It is strongly advised that you label wiring for all devices in the system
when necessary.
Grounding Moxa EtherDevice Switch
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.
Wiring the Alarm Contact
The Alarm Contact consists of the two middle contacts of the terminal
block on the EDS’s top panel. You may refer to the next 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.
In this section, we explain the meaning of the two contacts used to
connect the Alarm Contact.
FAULT: The two middle contacts of the
6
-contact terminal block connector
are used to
detect both power faults and port faults. The
two wires attached to the Fault contacts form
a
n open circuit when:
1. EDS has lost power from one of the AC/
DC power inputs.
OR
2. The PORT ALARM DIP switch for one of
the port
s is set to ON, but the port is not
connected properly.
If
neither of these two conditions is satisfied,
the Fault circuit will be closed.

Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact
terminal block connector on the EDS’s top panel are used for the EDS’s
two AC/ DC inputs. Top and front views of one of the terminal block
connectors are shown here.
STEP 1:
Insert the negative/positive AC/ DC wires into
the
V-/V+ terminals.
STEP 2:
To keep the AC/
DC wires from pulling loose,
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 EDS’s top panel.
ATTENTION
Before connecting
the EDS to the AC/
DC power inputs, make sure
the AC/DC power source voltage is stable.
Communication Connections
EDS-G308 models have 8 10/100/1000BaseT(X) Ethernet ports, or 6
10/100/1000BaseT(X) and 2 combination ports—10/100/1000T(X) and
100/1000BaseSFP.
10/100/1000BaseT(X) Ethernet Port Connection
The 10/100/1000BaseT(X) ports located on Moxa EtherDevice Switch’s
front panel 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) connected to the port.
In what follows, 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.

The concept behind the LC port and cable is quite straightforward.
Suppose you are connecting devices I and II. Unlike electrical signals,
optical signals do not require a circuit in order to transmit data.
Consequently, one of the optical lines is used to transmit data from device
I to device II, and the other optical line is used to transmit data from
device II to device I, for full-duplex transmission.
Remember to connect the Tx (transmit) port of device I to the Rx (receive)
port of device II, and the Rx (receive) port of device I to the Tx (transmit)
port of device II. If you make your own cable, we suggest labeling the two
sides of the same line with the same letter (A-to-A and B-to-B, as shown
below, or A1-to-A2 and B1-to-B2).

ATTENTION
This is a Class 1 Laser/LED product. To avoid causing serious
damage to your eyes, do not stare directly into the Laser Beam.
Redundant Power Inputs
Both power inputs can be connected simultaneously to live AC/DC power
sources. If one power source fails, the other live source acts as a backup,
and automatically supplies all of the EDS’s power needs.
Alarm Contact
The Moxa EtherDevice Switch has one Alarm Contact located on the top
panel. For detailed instructions on how to connect the Alarm Contact
power wires to the two middle contacts of the 6-contact terminal block
connector, see the Wiring the Alarm Contact section on page 6. A
typical scenario would be to connect the Fault circuit to a warning light
located in the control room. The light can be set up to switch on when a
fault is detected.
The Alarm Contact has two terminals that form a Fault circuit for
connecting to an alarm system. The two wires attached to the Fault
contacts form an open circuit when (1) EDS has lost power from one of
the AC/DC power inputs, or (2) one of the ports, for which the
corresponding PORT ALARM DIP switch is set to ON, is not properly
connected.
If neither of these two conditions occurs, the Fault circuit will be closed.
