Overview

We describe two products in this manual:

The MOXA EtherDevice™ EDS-P308 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 can double as a piece of power source equipment (PSE). When

used in this way, the EDS-P308 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. 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 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 is presented on pages 3 to 10. The

installation of the SPL-24 is presented on pages 11 to 14.

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

MOXA provides a complete end-to-end solution for any IEEE 802.3af PoE

compliant unit and Ethernet-enabled device. The EDS-P308 and SPL-24 can

be used to simplify wiring in the field, and provide a more versatile

—2 —

environment for installing devices. PoE technology lets you eliminate the

need for using power outlets to deploy Ethernet-enabled devices—such as a

wireless access point (AP) or an IP camera—on a ceiling or outdoors. The

devices can be placed up to 328 feet (100 m) from a PSE.

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

connections and to the signal contact with the Safety Extra-Low

Voltages (SELV) in compliance with IEC950/ EN60950/

VDE0805.

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/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:

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.

yNOTE: 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.

yYou 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.

yKeep input wiring and output wiring separated.

yIt is strongly advised that you label 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 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.

Wall Mounting (optional)

For some applications, you will find it convenient to mount EDS-P308 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 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 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

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’s 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’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.

Top View

Front View

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 EDS’s top

panel.

ATTENTION

Before connecting EDS to the DC power inputs, make sure the

DC power source voltage is stable.

EDS-P308’s Alarm Contact

The EDS-P308 has one alarm contact located on its 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 9. 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 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.

EDS-P308’s DIP Switch Settings

12345678

ON DIP

ON: Enables the corresponding PORT Alarm. If

the port’s link fails, the relay will form an

open circuit and the fault LED will light up.

Off: Disables the corresponding PORT Alarm.

The relay will form a closed circuit and the

Fault LED will never light up.

Wiring the Alarm Contact

The alarm contact consists of the two middle contacts of the terminal block on

EDS’s top panel. Refer to page 8 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

Top View

Front View

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. EDS has lost power from one of the DC

power inputs.

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.
