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.

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.
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 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:
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
through the same wire conduit. To avoid interference, wires with different
signal characteristics should be routed separately.
yUse 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 separate.
yIt 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.

V1- V1+V2- V2+
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.
