DIN-Rail Mounting
The DIN-Rail attachment plates are permanently fixed to the back panel of
EDS-726. Do not attempt to remove the attachment plates, since doing so could
damage the product.
STEP 1:
Insert the top of the DIN-Rail into the
notches at the bottom of the top array
of heat radiating ribs.
STEP 2:
The bottom of the DIN-Rail will snap
into place behind the DIN-Rail
attachment plate.

As shown in the figure at the right,
use a flat-blade screw driver as a lever
to force the DIN-Rail attachment
plates downwards, and then pull
EDS-726 out away from the
DIN-Rail. The DIN-Rail attachment
plates have an internal spring that
keeps the attachment plate pushed
upwards.

Wall Mounting (optional)
For some applications, you will find it convenient to mount EDS-726 on the
wall, as illustrated below.
STEP 1: Remove the aluminum DIN-Rail attachment plate from EDS-726’s
rear panel, and then attach the wall mounting plates, as shown in the diagram.
STEP 2:
Mounting EDS-726 on the wall requires 4 screws to ensure
that the switch does not come loose from the wall. Use the
switch, with wall mounting 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.
6.0 mm
3.5 mm

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 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 Moxa
EDS 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 EDS-726.
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 guidelines:
yUse 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.
yNOTE: 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.
yYou 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.

yKeep input wiring and output wiring separated.
yIt 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, on the side panel of EDS-726, 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
In this section, we explain the meaning of the two contacts used to connect the
alarm contact.
EDS-726 has two sets of relay output—relay 1 and relay 2. Each relay contact
consists of the two contacts of the terminal block on EDS-726’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.

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 will be
closed.
Wiring the Redundant Power Inputs
EDS-726 has two sets of power input—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’s top panel are used for EDS’s two digital inputs.

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-726’s top panel.

Wiring the Digital Inputs
EDS-726 has two sets of digital input—DI 1 and DI 2. Each DI comprises two
contacts of the 6-pin terminal block connector on EDS’s top panel. The
terminal block is also used for EDS’s two DC inputs. Top and front views of
one of the terminal block connectors are shown here.

STEP 2: To keep the DI wires

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-726’s top panel.
Communication Connections
The pinout and cable wiring diagrams in this section show how the ports on
EDS-726 connect to other devices:
Pinouts are diagrams that indicate the type of signal passing through each of
the port’s pins.
NOTE 1. The pin numbers for male DB9 and DB25 connectors, and hole
numbers for female DB9 and DB25 connectors are labeled on the
connector. However, the numbers are typically quite small, so you
may need to use a magnifying glass to see the numbers clearly.
2. The pin numbers for both 8-pin and 10-pin RJ45 connectors (and
ports) are typically not labeled on the connector (or port). Refer to
the Pinout diagram below to see how RJ45 pins are numbered.
RS-232 Connection
EDS-726 has one RS-232 (10-pin RJ45) console port, located on the side panel.
Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect Moxa
EDS-726’s console port to your PC’s COM port. You may then use a console
terminal program, such as Moxa PComm Terminal Emulator or Hyper
Terminal, to access Moxa EDS-726’s console configuration utility.

10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on EDS-726’s front panel are used to
connect to Ethernet-enabled devices.

(HUB/Switch-type) ports.

100/1000BaseFX Ethernet Port Connection
The concept behind the SC/ST port and cable is quite 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 to transmit data from device II to device I, for
full-duplex transmission.
All you need to remember is to connect the Tx (transmit) port of device I to the
Rx (receive) port of device II, and the Rx (receive) port of device I to the Tx
(transmit) port of device II. If you make your own cable, we suggest labeling
the two sides of the same line with the same letter (A-to-A and B-to-B, as
shown below, or A1-to-A2 and B1-to-B2).
