DIN-Rail Mounting

The aluminum DIN-Rail attachment plate should already be fixed to the

back panel of the EDS-405A/408A 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 following figures.

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.

To remove the Moxa EtherDevice switch from the DIN-Rail, simply

reverse Steps 1 and 2.

Wall Mounting (optional)

For some applications, you will find it convenient to mount the

EDS-405A/408A on the wall, as shown in the following figures.

STEP 1:

Remove the aluminum

DIN

-Rail attachment plate

from

the EDS-405A/408A’s

rear panel, and then attach

the wall mount plates

with

M3 screws

, as shown in the

diagram

at the right.

STEP 2:

Mounting

the EDS-405A/408

A 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.

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 completely—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-405A/408A downwards, as indicated. Tighten the four screws for

added stability.

Wiring Requirements

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.

Be sure to read and follow these important guidelines:

•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

through the same wire conduit. To avoid interference, wires with

different signal characteristics should be routed separately.

•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 separate.

•When necessary, you should label the wiring to all devices in the

system.

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 Relay Contact

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

block on the EDS-405A/408A’s top panel. 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:

A relay warning event

is triggered.

he EDS-405A/408A is

the Master of this Turbo

Ring, and the Turbo Ring

is broken.

There is a s

tart-up failure.

none of these three conditions is satisfied,

the fault circuit will remain 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-405A/408A’s top panel are used for

the EDS-405A/408A’s two DC inputs. Top and front views of one of the

terminal block connectors are shown in the following figures:

STEP 1: Insert the negative/positive DC wires

into the

V-/V+ terminals, respectively.

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 termi

nal block connector.

STEP 3:

Insert the plastic terminal block

connector prongs into the terminal block

receptor, which is

located on the

EDS-405A/408A’s top panel.

ATTENTION

Before connecting

the EDS-405A/408A to the DC power inputs,

make sure the DC power source voltage is stable.
