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 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 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.

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 an 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

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.

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.

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 with

similar electrical characteristics can be bundled together.

yKeep input wiring and output wiring separated.

yIt 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

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 AC/

DC power inputs.

2. The PORT ALARM DIP switch for one of

the ports 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.

Top View

Front View

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.

100Base-FX or 1000Base-X Fiber Port

The Fiber ports on the EDS-G308 series are SFP type slots, which support both

100Base-FX and 1000Base-X speed fiber transceiver to work properly. Moxa

provides complete transceiver models for various distance requirements.

Multi-mode:

1000BaseSX 0 to 550 m, 850 nm (50/125μm, 400MHz*km)

0 to 275 m, 850 nm (62.5/125μm, 200MHz*km)

1000BaseLX 0 to 1100 m, 1310 nm (50/125μm, 800MHz*km)

0 to 550 m, 1310 nm (62.5/125μm, 500MHz*km)

Single-mode:

1000BaseLX 0 to 10 km, 1310 nm (9/125μm, 3.5 PS/(nm*km))

1000BaseLHX 0 to 40 km, 1310 nm (9/125μm, 3.5 PS/(nm*km))

1000BaseZX 0 to 80 km, 1550 nm (9/125μm, 19 PS/(nm*km))

Multi-mode:

100BaseFx 0 to 5 km, 1300 nm (50/125μm, 800MHz*km)

0 to 4 m, 1300 nm (62.5/125μm, 500MHz*km)

Single-mode:

100BaseFx 0 to 40 km, 1310 nm (9/125μm, 3.5 PS/(nm*km))

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.
