DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the
back panel of the EDS-505A/508A when you take it out of the box.
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.
To remove EDS-505A/508A from the DIN-Rail, simply reverse Steps 1
and 2.
Wall Mounting (optional)
For some applications, you will find it convenient to mount the
EDS-505A/508A on the wall, as shown in the following figures.
STEP 1:
Remove the aluminum DIN
-
Rail
attachment plate from
the
EDS
-505A/508A’s rear panel,
and then attach the wall mount
plates
with M3 screws
, as shown
in
the figures at the right.
STEP 2:
Mounting
the EDS-505A/508A on the wall requires 4
screws. Use the
EDS
, 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 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 completely—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 the
EDS-505A/508A downwards, as indicated. Tighten the four screws for
added stability.

Wiring Requirements
WARNING
The power for this product is intended to be supplied by a Listed
Power Unit, with output marked
LPS, and rated to deliver 12 to
45
VDC at a maximum of 600 mA.
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.
Please read and follow these important guidelines:
•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.
•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 separate.
•It is strongly advised that you label wiring to all devices in the system,
when necessary.

Grounding the 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 Relay Contact
The EDS-505A/508A has two sets of relay output—relay 1 and relay 2.
Each relay contact consists of two contacts of the terminal block on the
EDS-505A/508A’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.
The fault circuit will open if:
1. A relay warning event is triggered, OR
2. The EDS-505A/508A is the Master of this Turbo Ring, and the Turbo
Ring is broken, OR
3. Start-up failure.
If none of these three conditions is met, the fault circuit will remain
closed.
Wiring the Redundant Power Inputs
The EDS-505A/508A unit has two sets of power inputs—power input 1
and power input 2. Top and front views of one of the terminal block
connectors are shown below.
Take the following steps to wire the redundant power 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 the EDS’s top panel.

ATTENTION
Before connecting
the EDS to the DC power inputs
, make sure the
DC power source voltage is stable.
Wiring the Digital Inputs
The EDS-505A/508A unit 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
the EDS’s top panel. The remaining contacts are used for the EDS’s two
DC inputs. Top and front views of one of the terminal block connectors are
shown below.
Take the following steps to wire the digital inputs:
STEP 1: Insert the negative (ground)/positive DI wires into the ┴/I1
terminals.
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-505A/508A’s top
panel.
Communication Connections
EDS-508A models have 8 or 6 10/100BaseT(X) Ethernet ports, and 0
(zero) or 2 100BaseFX (SC/ST-type connector) fiber ports. EDS-505A
models have 5 or 3 10/100BaseT(X) Ethernet ports, and 0 (zero) or 2 100
BaseFX (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.
Next, 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.
