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 right.

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 grounding cable is secured between the grounding screw and the ground for surge protection on the terminal block. Ground for surge protection is on terminal 3 of the terminal block as shown below. This product is to be mounted to a well- grounded mounting surface, such as a metal panel.3 For the 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)

  1. 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 inputs—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. The top and front views of one of the terminal block connectors are also shown below.

Wiring the Power Input (110/220 VDC/VAC model)
The PT-508 unit (110/220 VDC/VAC model) has one set of power inputs—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. The top and front views of one of the terminal block connectors are also shown below.

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.

When connecting device 1 to device 2, remember to connect the Tx (transmit) port of device 1 to the Rx (receive) port of device 2, and the Rx (receive) port of device 1 to the Tx (transmit) port of device 2. 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).
