DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the back
panel of the EDS-408A 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 following figures.
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.

To remove the Moxa EtherDevice switch from the DIN-Rail, simply reverse
Steps 1 and 2.
Wall Mounting (optional)
For some applications, you will find it convenient to mount the EDS-408A on
the wall, as shown in the following figures.
STEP 1: Remove the
aluminum DIN-Rail
attachment plate from the
EDS-408A’s rear panel, and
then attach the wall mount
plates with M3 screws, as
shown in the diagram at the
right.

STEP 2:
Mounting the EDS-408A on the wall requires 4 screws.
Use the switch, 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.
6.0 mm
3.5 mm
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 completely—leave about 2 mm to allow room for
sliding the wall mount panel between the wall and the screws.

—7 —
STEP 3: Once the screws are fixed on the
wall, insert the four screw heads through
the large parts of the keyhole-shaped
apertures, and then slide the EDS-408A
downwards, as indicated. Tighten the four
screws for added stability.

Wiring Requirements
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.
Be sure to read and follow these important guidelines:
yUse 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.
yUse 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.
yKeep input wiring and output wiring separate.
yIt 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 Relay Contact
The Relay Contact consists of the two middle contacts of the terminal block on
the EDS-408A’s top panel. 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.
Relay
Relay
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 an open
circuit when:
1. A relay warning event is triggered.
OR
2. The EDS-408A is the Master of this Turbo
Ring, and the Turbo Ring is broken.
OR
3. Start-up failure.
If none of these three conditions is satisfied, the
fault circuit will remain 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-408A’s top panel are used for the EDS-408A’s
two DC inputs. Top and front views of one of the terminal block connectors are
shown in the following figures:
PWR1

V1+ V1- V2+ V2-
V1+ V1- V2+ V2-
PWR2
PWR2
STEP 1: Insert the negative/positive DC wires
into the V-/V+ terminals, respectively.
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-405A/408A’s top panel.

ATTENTION
Before connecting the EDS-408A to the DC power inputs, make
sure the DC power source voltage is stable.
Communication Connections
EDS-408A models have 8, 6 or 5 10/100BaseT(X) Ethernet ports, and 0 (zero),
2 or 3 100BaseFX (SC/ST-type connector) fiber ports.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the EDS’s front panel are used to
connect to Ethernet-enabled devices.
Next, we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.
