DIN-Rail Mounting
The aluminum DIN-Rail attachment plate should already be fixed to the
back panel of the PT-508 when you take it out of the box. If you need to
reattach the DIN-Rail attachment plate to the PT-508, make sure the stiff
metal spring is situated towards the top as shown in the figures below.
STEP 1: If the spring-loaded
bracket is locked in place,
push the recessed button to
release it. Once released, you
should feel some resistance
from the spring as you slide
the bracket up and down a few
millimeters in each direction.
STEP 2:
Insert the top of
the DIN-Rail
into the top slots on the
DIN-Rail attachment plate.
STEP 3:
The DIN
-
Rail attachment unit will snap
into place as shown in the following
illustration.
To remove the Moxa PT
-508
switch from the DIN
-Rail, use a
screwdriver to push down
the
spring
-
loaded bracket until it locks
in place, as shown in the following
diagram. Next, rotate the bottom
of the switch upwards and then
remove the switch from the
DIN
-Rail.

Wall Mounting (optional)
For added convenience, the PT-508 can be wall mounted as illustrated
below.
STEP 1: Remove the
aluminum DIN
-Rail
attachment plate from
the
PT
-508
’s rear panel, and then
attach the wall mount plates
with
6 M3 screws, as shown
on
the right.
STEP 2: Mounting the PT-508 to a wall requires 4
screws. Use the
PT-508, with wall mount plates attached,
as a guide to mark the correct locations for 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 on the righ
t.
NOTE
Test the screw’s head and shank size by inserting the screw into
one of the keyhole
-shaped apertures of the wall mounting plates
before screwing it into the wall.
DO NOT screw the screws all the way in—leave a space of about 2 mm to
allow room for sliding the wall mount panel between the wall and the
screws.
STEP 3: After the screws are fixed into the wall, insert the four screw
heads through the large opening of the keyhole-shaped apertures, and
then slide the PT-508 downwards. Tighten the 4 screws for added
stability.
Wiring Requirements
WARNING
Safety First!
Be sure the power cord is disconnected before installing and/or
wiring your
PT-508.
Calculate the maximum possible current in each power
wire and
common wire. Observe all electrical codes dictating the
maximum current allowed for each wire size. If the current goes
above the maximum rating, 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
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. As a rule of thumb,
wiring with 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.
Grounding the PowerTrans Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground wire from the
grounding screw to the grounding surface prior to connecting devices.
ATTENTION
Before
powering on the PT-508 (24/48 VDC models), make sure
that the g
rounding cable is secured between the
grounding screw
and ground for surge protection on the
terminal block.
Ground for
surge protection is on terminal 3 of the terminal block as shown
below.
ATTENTION
This product is to be mounted to a well
-grounded mounting
surface, such as a metal panel.
ATTENTION
For dielectric strength (HIPOT) test, users must remove the
grounding cable secured between the grounding
screw and
ground for surge protection located at terminal 3 of the terminal
block to avoid damage.

Wiring the Relay Contact
The PT-508 has one set of relay output—relay 1. The relay contact
consists of two contacts of the terminal block on the PT-508’s bottom
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 PT-508 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 (24/48 VDC models)
The PT-508 (24/48 VDC models) 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 PT’s bottom panel.
ATTENTION
Before connecting
the PT
to the DC power inputs, make sure the
DC power source voltage is stable.

Wiring the Power Input (110/220 VDC/VAC model)
The PT-508 unit (110/220 VDC/VAC model) has one set of power input—
Pin 1(Neutral) and Pin5(Line). To insert the terminal block connector
prongs into the terminal block receptor on this PT-508 unit properly.
Please take the following steps to wire the power input. Top and front
views of one of the terminal block connectors are also shown below.
Take the following steps to wire the power input:
STEP 1: Insert the Neutral/Line AC or Negative/Positive DC wires into the
terminals (Terminal 1 for Neutral/Negative and Terminal 5 for
Line/Positive) of the terminal block connector.
STEP 2: To keep the AC or 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 PT’s bottom panel.
NOTE: The PT-508 unit (110/220 VDC/VAC model) has the reverse
protection mechanism for 110/220 VDC input.
ATTENTION
Before connecting the PT to the DC power inputs, make sure the
DC power source voltage is stable.
Wiring the Digital Inputs
The PT-508 unit has one set of digital input, DI 1. The DI consists of two
contacts from the 4-pin terminal block connector on the PT’s bottom
panel. The remaining contacts are used for the PT’s Relay 1. Top and front
views of one of the terminal block connectors are shown below.
Take the following steps to wire the digital input:
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 PT-508’s bottom panel.

Pin Assignments
PT-508 models have six 10/100BaseT(X) Ethernet ports, and two
100BaseFX (SC/ST/LC/MTRJ-type connector) fiber ports.
10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on PT’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.
