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

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

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

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 s

crew 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 a

n 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

maxim

um 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 with similar electrical characteristics can be bundled

together.

•Keep input wiring and output wiring separated.

•It 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: The two middle contacts of the

-contact terminal block connector

are used to

detect both power faults and port faults. The

two wires attached to the Fault contacts form

n 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 port

s is set to ON, but the port is not

connected properly.

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.

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

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.

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.
