Overview
Moxa’s EtherDevice™ EDS-305 are smart Ethernet switches that provide
an economical solution for your Ethernet connections. As an added bonus,
the built-in smart alarm function helps system maintainers monitor the
health of your Ethernet network.
The EDS-305 have a wide operating temperature range of -40 to 75°C,
and are designed to withstand a high degree of vibration and shock. The
rugged hardware design makes either model perfect for ensuring that
your Ethernet equipment can withstand critical industrial applications,
and complies with FCC and CE Standards.

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 EDS from the DIN-rail, simply reverse Steps 1 and 2
above.
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, a
s shown in
the diagram below.
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
keyholeshaped 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 screw 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.
ATEX Information

5. The conditions of safe usage:
•
The Ethernet Communication Devices are to be mounted in an
IP54 enclosure and used in an area of not more than pollution
degree 2 as defined by IEC 60664-1.
•A 4mm2conductor must be used when connection to the
external grounding screw is utilized.
•Conductors suitable for use in an ambient temperature of 93°
C
must be used for the Power Supply Terminal.
Provisions shall be
made to prevent the rated voltage being exceeded by the

Wiring Requirements
WARNING
Do not disconnect modules or wires unless the power supply has
been switched
off or the area is known to be non-hazardous.
The
devices may only be connected to the supply voltage shown on
the type plate.
The devices are designed for operation with a
Safety Extra-Low
Voltage. Thus, they may only be connected to the supply voltage
c
onnections and to the signal contact with the Safety Extra-L
ow
Voltages (SELV) in compliance with IEC950/ EN60950/ VDE0805.
WARNING
Substitution of components may impair suitability for Class
I,
Division 2
, and Zone 2. These devices must be supplied by an
SELV source as defined in Low Voltage Directive 73/23/EEC and
93/68/EEC.

WARNING
This unit is a built
-in type. When the unit is installed in another
piece of equipment, the equipment
enclosing the unit must
comply with fire enclosure regulation IEC 60950/EN60950 (or
similar regulation).
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your
Moxa EtherDevice Switch.
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.
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 that shares similar electrical characteristics can be
bundled together.
•Keep input wiring and output wiring separated.
•It is strongly advised that you label wiring to all devices in the system
when necessary.
Grounding the 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 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. The EDS has lost power from one of the
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 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 DC inputs. Top and front views of one of the terminal block
connectors are shown here.
STEP 1:
Insert the negative/positive DC wires into the
V
-/V+ terminals.
STEP 2:
To keep the 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 the EDS’s top panel.
ATTENTION
Before connecting
the
EDS to the DC power inputs, make sure the
DC power source voltage is stable.
