DIN-Rail Mounting

The aluminum DIN-Rail attachment plate should already be fixed to the back panel of EDS when

you take it out of the box. If you need to reattach the DIN-Rail attachment plate to EDS, 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 MOXA EtherDevice Switch from the DIN-Rail, simply reverse Steps 1 and 2 above.

Wall Mounting (OPTIONAL)

For some applications, you will find it convenient to mount MOXA EtherDevice Switch on the

wall, as illustrated below.

STEP 1:

Remove the aluminum DIN-Rail attachment plate from MOXA EtherDevice Switch’s rear panel,

and then attach the wall mount plates, as shown in the diagram below.

⇒

plate

STEP 2:

Mounting MOXA EtherDevice Switch 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 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.

6.0 mm

3.5 mm

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 MOXA EtherDevice Switch downwards,

as indicated below. Tighten the four screws for added stability.

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

Substitution of components may impair suitability for Class

I, Division 2 and Zone 2.

These devices must be supplied by a SELV source as defined in the Low Voltage Directive

73/23/EEC and 93/68/EEC.

WARNING

This equipment has been evaluated as EEx nC IIC T4 equipment under DEMKO Certificate No.

03 ATEX 0324537U. Each module is marked II 3G and is suitable for use in Zone 2

Explosive Atmospheres. The device must be installed in a minimum IP 54 enclosure as defined in

IEC 60529 and EN 60529.

ATTENTION

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).

ATTENTION

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 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 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 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.

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.
