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

-508

’s rear panel, and then

attach the wall mount plates

with

6 M3 screws, as shown

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

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

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.

- 7 -

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.
