Mounting Dimensions
Unit = mm (inch)
DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the
back panel of EDS-316 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
t
he 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 EDS-316 on
the wall, as illustrated in the figure.
STEP 1: Remove the
aluminum DI
N-Rail
attachment plate from
EDS
-316’s rear panel, and
then attach the wall mount
plates, as shown in the
figu
re.
STEP 2:
Mounting EDS-316 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.
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 EDS
-316
downwards, as indicated. 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
V
oltage. Thus, the
y may only be connected to the supply voltage
connections and to the signal contact with the
Safety Extra-L
ow
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 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.

- 9 -
•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:
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.
The PORT ALARM DIP Switch for one of the ports
is set to ON, but the port is not connected
properly.
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.
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.
Communication Connections
EDS-316 models have 14, 15, or 16 10/100BaseT(X) Ethernet ports, and
2, 1, or 0 (zero) 100BaseFX (SC/ST-type connector) fiber ports.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on EDS’s front panel are used to
connect to Ethernet-enabled devices.
Below we show pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports, and also show cable wiring diagrams for
straight-through and cross-over Ethernet cables.

100BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is very straightforward.
Suppose you are connecting devices I and II. Contrary to 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 transmit data from device
II to device I, for full-duplex transmission.
