Overview
We describe two products in this manual:
The Moxa EtherDevice™ EDS-P308 Series is an 8-port smart Ethernet
switch that provides an economical solution for your Ethernet connections.
The switch supports PoE (Power-over-Ethernet) on ports 1 to 4, which
means that the EDS-P308 Series can double as a piece of power source
equipment (PSE). When used in this way, the EDS-P308 Series can supply
up to 15.4 watts of power per port, and can power IEEE 802.3af compliant
powered devices (PD), eliminating the need for additional wiring. The
EDS-P308 Series switch is highly versatile, and its FX fiber port can
transmit data up to 40 km from the device to the control center with high
EMI immunity. As an added bonus, the built-in smart alarm function helps
system maintainers monitor the health of your Ethernet network.
The SPL-24 plays the role of PD, and splits the data signal and power
signal that are transmitted from the PSE. The SPL-24 plays a dual role of
providing power to industrial devices, and enabling Ethernet connections.
The EDS-P308 and SPL-24 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 the EDS-P308 Series and
SPL-24 perfect for ensuring that your Ethernet equipment can operate in
critical industrial environments, such as in hazardous locations, and
complies with FCC and CE standards.
The installation of the EDS-P308 Series is presented on pages 3 to 11. The
installation of the SPL-24 is presented on pages 11 to 15.
NOTE
Throughout this Hardware Installation Guide, we use EDS as an
abbreviation for Moxa EtherDevice Switch, and we use SPL as an
abbreviation for Moxa PoE Splitter:
EDS = Moxa EtherDevice Switch
SPL = Moxa PoE Splitter

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 a
re designed for operation with a
Safety Extra
-
Low Voltage. Thus, they may only be connected to
the supply voltage connections and to the signal contact with the
Safety Extra
-Low Voltages (SELV) in compliance with IEC
60950-1/EN 60950-1.
WARNING
The power for this product is intended to be supplied by a Listed
Power Unit, with output marked LPS, and rated to deliver 48 VDC
at a maximum of 300 mA.
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
-1/EN60950-1
(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 the input wiring and the output wiring separated.
•It is strongly advised that you label the wiring to all devices in the
system when necessary.

DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the
back panel of the EDS-P308 Series 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 pla
ce as shown below.
To remove the Moxa EtherDevice Switch from the DIN-Rail, simply
reverse Steps 1 and 2 above.
Wall Mounting (optional)
For some applications, you will find it convenient to mount EDS-P308
Series on the wall, as illustrated below.
STEP 1:
Remove the aluminum
DIN
-Rail attachment plate
from the EDS
-P308’s rear
panel, and then attach the
wall mount plates, as shown
in the diagram below.
STEP 2:
Mounting the EDS-
P308 on the wall requires 4
screws. Use the switch, with wall mount pla
tes
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 the 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 screw heads through the
large parts of the keyhole
-shaped
apertures, and then slide the EDS
-P308
downwards, as indicated. Tighten the four
screws for added stability.
Grounding the EDS-P308 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.
EDS-P308 Series’ Redundant Power Inputs
Both power inputs can be connected simultaneously to live DC power
sources. If one power source fails, the other live source acts as a backup,
and automatically supplies all of EDS-P308 Series’s power needs.
Wiring the Redundant Power Inputs
The top two contacts and the bottom two contacts of the 6-contact
terminal block connector on EDS’s top panel are used for 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 ED
S’s top panel.
ATTENTION
Before connecting EDS to the DC power inputs, make sure the DC
power source voltage is stable.
