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
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.
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 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.
