DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the
back panel of EDS-516A when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to EDS-516A, make sure the stiff
metal spring is situated towards the top, as shown by the following
figures.
STEP 1ȹInsert the top of the
DIN-Rail into the slot just below the
stiff metal spring.
STEP 2ȹThe DIN-Rail attachment
unit will snap into place as shown in
the following illustration.
To remove the EDS-516A 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
EDS-516A on the wall, as shown by the following illustrations:
STEP 1—Remove the
aluminum DIN-Rail
attachment plate from the
Moxa EDS-516A rear
panel, and then attach the
wall mount plates with M3
screws, as shown by the
figure on the right.
STEP 2—Mounting Moxa EDS-516A on the wall
requires 4 screws. Use the EDS-516A, 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 by
the figure on the right.
NOTE Before tightening the screws into the wall, make sure the screw
head and shank size are suitable by inserting the screw through
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 to the wall, insert the four
screw heads through the wide
parts of the keyhole-shaped
apertures, and then slide the
EDS-516A downwards, as
indicated in the figure at the right.
Tighten the four screws for more
stability.

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 IEC60664-1.
A 4mm2 conductor must be used when connection to the
external grounding screw is utilized.
Conductors suitable for use in an ambient temperature of 93°C
must be used for the Power Supply Terminal.
Provisions shall be made, either in external to the apparatus, to
prevent the rated voltage being exceeded by the transients
disturbances of more than 40%.
Wiring Requirements
WARNING
Do not disconnect modules or wires unless power 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.
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 points:
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
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
Separate input wiring and output wiring
We advise that you label wiring to all devices in the system when
necessary.
Grounding the Moxa EDS-516A
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
EDS-516A has two sets of relay outputs—relay 1 and relay 2. Each Relay
Contact consists of the two contacts of the terminal block on EDS-516A’s
top panel. You can 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 will explain the meaning of the two contacts used to
connect the Relay Contact.
FAULT:
The two sets of relay contacts of
the 6-pin terminal block connector
are used to detect user-configured
events. The two wires attached to
the fault contacts form an open
circuit when a user-configured
event is triggered. If a
user-configured event does not
occur, the fault circuit remains
closed.
Wiring the Redundant Power Inputs
EDS-516A has two sets of power inputs—power input 1 and power input
2.The top two contacts and the bottom two contacts of the 6-pin terminal
block connector on EDS’ top panel are used for EDS’ two digital inputs.
The 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, 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 terminal block connector.
STEP 3: Insert the plastic terminal
block connector prongs into the
terminal block receptor, which is
located on the EDS-516A’s top
panel.

Wiring the Digital Inputs
EDS-516A has two sets of digital inputs, DI 1 and DI 2. Each DI consists
of two contacts of the 6-pin terminal block connector on EDS’s top panel,
which are used for EDS’s two DC inputs. The top and front views of one of
the terminal block connectors are shown here.
STEP 1: Insert the negative
(ground)/positive DI wires into the
ʓ/I1 terminals, respectively.
STEP 2: To keep the DI 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 the EDS-516A’s top
panel.
Communication Connections
All models of EDS-516A have one RJ45 console port (RS-232 interface),
between 14 and 16 10/100BaseTX Ethernet ports. Some models also
have 2 100BaseFX (SC/ST-type connector) fiber ports.
In this section, we present two types of diagrams—Pinout Diagrams and
Cable Wiring Diagrams—to convey information about the ports and the
cables used to connect Moxa EDS-516A to other devices:
Pinouts—The meaning of the “Pinouts” diagrams is straightforward. The
diagrams simply display the type of signal passing through each of the
port’s pins.
Cable Wiring—Diagrams labeled “Cable Wiring” present standard cable
wiring schemes for cables used to connect Moxa EtherDevice Switch’s
ports to other devices. These diagrams display three pieces of
information:
1. When building your own cable, refer to the “pin-to-pin” Cable
Wiring information displayed between the two vertical dashed lines
to see which pin of the connector on the left should be connected to
which pin of the connector on the right.
2. The information to the left of the left vertical dashed lines gives the
pinouts of the relevant Moxa EtherDevice Switch port.
3. The information to the right of the right vertical dashed line gives the
pinouts of the opposing device’s port.
