Overview

Moxa’s EtherDevice™ EDS-305 are smart Ethernet switches that provide

an economical solution for your Ethernet connections. As an added bonus,

the built-in smart alarm function helps system maintainers monitor the

health of your Ethernet network.

The EDS-305 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 either model perfect for ensuring that

your Ethernet equipment can withstand critical industrial applications,

and complies with FCC and CE Standards.

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 EDS from the DIN-rail, simply reverse Steps 1 and 2

above.

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, a

s shown in

the diagram below.

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

keyholeshaped 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.

ATEX Information

1. Certificate number DEMKO 08 ATEX 0812123x

2. Ambient range (-40°C ≤Tamb ≤75°C)

3. Certification string (Ex nA nC IIC T4 Gc)

4. Standards covered ( EN 60079-0:2012, EN 60079-15:2010)

5. The conditions of safe usage:

•

The Ethernet Communication Devices are to be mounted in an

IP54 enclosure and used in an area of not more than pollution

degree 2 as defined by IEC 60664-1.

•A 4mm2conductor must be used when connection to the

external grounding screw is utilized.

•Conductors suitable for use in an ambient temperature of 93°

must be used for the Power Supply Terminal.

Provisions shall be

made to prevent the rated voltage being exceeded by the

transient disturbances of more than 40%.

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

onnections and to the signal contact with the Safety Extra-L

Voltages (SELV) in compliance with IEC950/ EN60950/ VDE0805.

WARNING

Substitution of components may impair suitability for Class

Division 2

, and Zone 2. These devices must be supplied by an

SELV source as defined in Low Voltage Directive 73/23/EEC and

93/68/EEC.

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:

•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 input wiring and output wiring separated.

•It 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 Alarm Contact

The Alarm Contact consists of the two middle contacts of the terminal

block on 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. The 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.

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 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+ 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

located on the EDS’s top panel.

ATTENTION

Before connecting

the

EDS to the DC power inputs, make sure the

DC power source voltage is stable.
