DIN-rail Mounting
The DIN-rail mounting kit is fixed to the back panel of the EDS device when you take it out of the box. Mount the EDS device on corrosionfree mounting rails that meet
the EN 60715 standard.

Installation
STEP 1—Insert the upper lip of the DIN rail into the DIN-rail mounting kit.
STEP 2—Press the EDS device towards the DIN rail until it snaps into place.

Removal
STEP 1—Pull down the latch on the mounting kit with a  screwdriver.
STEP 2 & 3—Slightly pull the EDS device forward and lift up to remove it from the DIN rail.

NOTE Our DIN rail kit now utilizes a quick release mechanism to make it easier for users to remove the DIN rail from the EDS device.

Wall Mounting (Optional)
For some applications, you will find it convenient to mount the Moxa EDS device on a wall, as shown in the following illustrations:
STEP 1—Remove the DIN-rail attachment plate from the rear panel of the EDS device, and then attach the wall mount plates with M3 screws.

STEP 2—Mounting the EDS device on a wall requires four screws. Use the EDS device, with wall mount plates attached. 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 on at right.

NOTE Before tightening the screws into the wall, make sure the screw  head and shank size are suitable by inserting the screw through one of the keyhole-shaped apertures of the Wall Mounting Plates.
NOTE Do not screw the screws in all the way—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 to the wall, insert the four screw heads through the wide parts of the keyholeshaped apertures, and then slide the EDS device downwards, as indicated in the figure at the right. Tighten the four screws for more stability.

Wiring Requirements

ATTENTION
Safety First!
External metal parts are hot. Take the necessary precautions if you are required to handle the device.
ATTENTION
In order to ensure reliable operations, please make sure the operating temperature of the environment does not exceed the specifications. When mounting an EDS device with other operating units in a cabinet without forced ventilation, a minimum of 4 cm space on both the left and right of the switch is recommended.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your EDS device. 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.

Be sure to read and follow these important points below:

• 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.

• You can 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.
• You should separate input wiring from output wiring.
• We advise that you label the wiring to all devices in your system.

Grounding the Moxa EDS Series

Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw (M4) to the grounding surface prior to connecting devices.
NOTE The grounding wire should have a minimum diameter of 1.5 mm² .
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface such as a metal panel.
Suggested Wire Type for Wiring Relay Contact (RELAY), Digital Input (DI), and Power Inputs (P1/P2)
The EDS device includes two 4-pins 3.5 mm pin-pitch terminal blocks. When wiring the relay contact (RELAY), digital input (DI), and power inputs (P1/P2), we suggest using the cable type – AWG 18-24 and the corresponding pin type cable terminals.
NOTE The wire must be able to withstand at least 105°C and the torque value should be 4.5 lb-in (0.51 N-m).
NOTE We suggest the length of the pin type cable terminal is 8 mm. In order to tighten the wire properly, ① use a small flathead screwdriver to press the push-in button beside each terminal of the terminal block connector before and during ② inserting the wire. ③ Release the screwdriver after the wire has been fully inserted. Please refer to the diagram below.
Wiring the Relay Contact
The EDS device has one set of relay output. This relay contact uses two contacts of the terminal block on the EDS’s power module. Refer to the 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.

Relay:
The two contacts of the 4-pin terminal block connector are used to detect user-configured events. The two wires attached to the fault contacts form an open circuit when a user-configured event is triggered or there is no power supply to the switch. If a userconfigured event does not occur, the fault circuit remains closed.

Wiring the Redundant Power Inputs

The EDS device includes both high-voltage and low-voltage products. For the low-voltage (LV models) products, there are two power inputs for redundancy; for the high-voltage (HV models) products, there is only one power input. Refer to the instructions and diagram below on how to connect the wires to the terminal block connector on the receptor.

STEP 1: Insert the Positive/Negative DC or Line/Neutral AC wires into the V+/V- or L/N terminals, respectively.
STEP 2: To keep the DC or AC wires from pulling loose, use a small flatblade screwdriver to tighten the wireclamp 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 devices’ right side.

Wiring the Digital Inputs

The EDS device has one set of digital input (DI). The DI consists of two contacts of the 4-pin terminal block connector on the EDS’s right-side panel. Refer to the instructions and diagram below on how to connect the wires to the terminal block connector on the receptor.

STEP 1: Insert the negative (ground)/positive DI wires into the ┴/I terminals, respectively.
STEP 2: To keep the DI wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp button 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 devices’ right side.

Rotating the Power Module

The power module for the EDS device can be rotated to make it easier to fit your field site application.
Step 1: Remove the two screws that fasten the power module to the EDS device.
Step 2: Remove the power module.
Step 3: Turn the power module clockwise so that the power, digital input, and relay output connectors can be moved upwards.
Step 4: Place the module back on to the EDS device and then fasten the two screws on to the module.

Communication Connections

Each EDS-4008 Series switch has various types of communication ports:

• RJ45 console port (RS-232 interface)
• USB storage port (type A connector, currently disabled)
• microSD card slot (currently disabled)
• 10/100BaseTX Ethernet ports
• 100BaseFX (SC/ST-type connector) fiber ports
• 10/100/1000BaseT(X) Ethernet ports
• 100/1000BaseSFP ports

Console Port Connection
The EDS device has one RJ45 console port (RS-232), located on the front panel. Use either an RJ45-to-DB9 (see the cable following wiring diagrams) to connect the EDS’s console port to your PC’s COM port. You may then use a console terminal program, such as Moxa PComm Terminal Emulator, to access the EDS that has a baud rate of 115200.

NOTE The USB function is currently reserved and may be required in the future. It should be noted that this port cannot be used for charging any devices.

10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the front panel of the switch are used to connect to Ethernet-enabled devices. Most users will choose to configure these ports for Auto MDI/MDI-X mode, in which case the port’s pinouts are adjusted automatically depending on the type of Ethernet cable used (straight-through or cross-over), and the type of device (NIC-type or HUB/Switch-type) connected to the port. In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-type) ports. We also give cable wiring diagrams for straight-through and cross-over Ethernet cables.

100BaseFx Ethernet Port Connection
The concept behind the SC/ST port and cable is quite straightforward. Suppose you are connecting devices I and II. As opposed to electrical signals, optical signals do not require a circuit in order to transmit data. Consequently, one of the optical lines is used to transmit data from device I to device II, and the other optical line is used transmit data from device II to device I, for full-duplex transmission. All you need to remember is to connect the Tx (transmit) port of device I to the Rx (receive) port of device II, and the Rx (receive) port of device I to the Tx (transmit) port of device II. If you are making 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 by the following illustration, or A1-to-A2 and B1-to-B2).

ATTENTION
This is a Class 1 Laser/LED product. To prevent damage to your eyes, do not stare directly into the laser beam.

100/1000BaseSFP (mini-GBIC) Fiber Port 

The Gigabit Ethernet fiber ports on the switch are 100/1000BaseSFP fiber ports, which require using 100M or 1G mini-GBIC fiber transceivers to work properly. Moxa provides a complete selection of transceiver models for different distance requirements.
The concept behind the LC port and cable is straightforward. Suppose you are connecting devices I and II; contrary to electrical signals, optical signals do not require a circuit in order to transmit data. Consequently, one of the optical lines is used to transmit data from device I to device II, and the other optical line is used transmit data from device II to device I, for full-duplex transmission.
Remember to connect the Tx (transmit) port of device I to the Rx (receive) port of device II, and the Rx (receive) port of device I to the Tx (transmit) port of device II. 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).

ATTENTION
This is a Class 1 Laser/LED product. To avoid causing serious damage to your eyes, do not stare directly into the Laser Beam.

Reset Button

There are two functions available on the Reset Button. One is to reset the Ethernet switch to factory default settings by pressing and holding the Reset button for 5 seconds. Use a pointed object, such as a straightened paper clip or toothpick, to depress the Reset button. This will cause the STATE LED to blink once a second. After depressing the button for 5 continuous seconds, the STATE LED will start to blink rapidly. This indicates that factory default settings have been loaded and you can release the reset button. The other function is to reboot the device by depressing reset button for less than five seconds.

Turbo Ring DIP Switch Settings
The EDS devices are plug-and-play managed redundant Ethernet switches. The proprietary Turbo Ring protocol was developed by Moxa to provide better network reliability and faster recovery time. Moxa Turbo Ring’s recovery time is less than 50 ms (Turbo Ring V2) — compared to a 3- to 5-minute recovery time for commercial switches—
decreasing the possible loss caused by network failures in an industrial setting.
There are five Hardware DIP Switches for Turbo Ring on the bottom panel of the EDS device that can help setup the Turbo Ring easily within seconds. If you do not want to use a hardware DIP switch to setup the Turbo Ring, you can use a web browser, telnet, or console to disable this function.
NOTE Please refer to the Turbo Ring section in User’s Manual for more detail information about the setting and usage of Turbo Ring V2.
Turbo Ring DIP Switch Settings

The default setting for each DIP Switch is OFF. The following table explains the effect of setting the DIP Switch to the ON position.
Remove the rubber cover on the bottom panel of the device to expose the DIP switches.

NOTE You must enable the Turbo Ring (DIP switch 5) first before using the DIP switch to activate the Master and Coupler functions.
NOTE If you do not enable any of the EDS switches to be the Ring Master, the Turbo Ring protocol will automatically choose the EDS switch with the smallest MAC address range to be the Ring Master. If you accidentally enable more than one switch to be the Ring Master, these switches will auto-negotiate to determine which one will be the Ring Master.
