DIN-Rail Mounting

The aluminum DIN-Rail attachment plate should be fixed to the back panel of

IMC when you take it out of the box. If you need to reattach the DIN-Rail

attachment plate to IMC, make sure the stiff metal spring is situated towards

the top, as shown in the figures below.

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 below.

To remove Moxa Industrial Media Converter from the DIN-Rail, simply

reverse Steps 1 and 2 above.

Wall Mounting (Optional)

For some applications, you will find it convenient to mount Moxa Industrial

Media Converter on the wall, as illustrated below.

STEP 1:

Remove the aluminum DIN-Rail attachment plate from Moxa Industrial Media

Converter, and then attach the wall mount plates, as shown in the diagrams

below.

STEP 2:

Mounting Moxa Industrial Media Converter on the wall

requires 4 screws. Use the IMC, 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.

NOTE Test the screw head and shank size by inserting

the screw into one of the keyhole shaped

apertures of the Wall Mounting Plates, before it

is screwed into the wall.

Do not screw the screws in all the way—leave a space of

about 2 mm to allow room for sliding the wall mount

panel between the wall and the screws.

3.5 mm

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 Moxa Industrial

Media Converter downwards, as indicated below. Tighten the four screws for

added stability.

Wiring Requirements

WARNING

Do not disconnect modules or wires unless power has been

switched off or the area is known to be non hazardous.

The devices may only be connected to the supply voltage shown

on the type plate.

The devices are designed for operation with a safety extra-low

voltage. Thus, they may only be connected to the supply voltage

connections and to the signal contact with the safety extra-low

voltages (SELV) in compliance with IEC950/ EN60950/

VDE0805.

WARNING

Substitution of components may impair suitability for Class I,

Division 2 and Zone 2.

These devices must be supplied by a SELV source as defined in

the Low Voltage Directive 73/23/EEC and 93/68/EEC.

WARNING

This equipment has been evaluated as EEx nC IIC T4

equipment under DEMKO Certificate No. 03 ATEX

0324537U. Each module is marked with II 3G and is

suitable for use in Zone 2 Explosive Atmospheres. Devices

must be installed in a minimum IP 54 enclosure as defined in

IEC 60529 and EN 60529.

ATTENTION

This unit is a built-in type. During installation into certain

end equipment, it must comply with fire enclosure

stipulations of IEC 60950/EN60950, or similar statements.

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or

wiring your Moxa Industrial Media Converter.

ATTENTION

Safety First!

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.

You should also pay attention to the following points:

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.

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.

yYou 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.

yKeep input wiring and output wiring separated.

yIt is strongly advised that you label wiring to all devices in the system when

necessary.

Grounding Moxa Industrial Media

Converter

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 Alarm Contact

The Alarm Contact is made up of the two middle contacts of the terminal block

on IMC’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.

In this section, we explain the meaning of the two contacts used to connect the

Alarm Contact.

FAULT

Top View

Front View

FAULT: The two middle contacts of the

6-contact terminal block connector are used to

detect both power faults and port faults. The two

wires attached to the Fault contacts form an open

circuit when:

1. IMC has lost power from one of the DC

power inputs.

2. One of the ports for which the corresponding

PORT ALARM Dip Switch is set to ON is not

properly connected.

If neither of these two conditions occurs, the

Fault circuit will be closed.

Wiring the Redundant Power Inputs

The top two contacts and the bottom two contacts of the 6-contact terminal

block connector on IMC’s top panel are used for IMC’s two DC inputs. Top

and front views of one of the terminal block connectors are shown here.

Top View

Front View

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 IMC’s top panel.

ATTENTION

Before connecting IMC to the DC power inputs, make sure the DC

power source voltage is stable.

Communication Connections

IMC-101 models have one 10/100BaseT(X) Ethernet port, and one 100BaseFX

(SC or ST type connector) fiber port.

10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) ports located on IMC’s front panel are used to connect to

Ethernet-enabled devices.

Below 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.

100BaseFX Ethernet Port Connection

The concept behind the SC port and cable is quite 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.

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 below, or A1-to-A2 and B1-to-B2).

ATTENTION

This is a Class 1 Laser/LED product. Do not stare into the Laser

Beam.

Redundant Power Inputs

Both power inputs can be connected simultaneously to live DC power sources.

If one power source fails, the other live source acts as a backup, and

automatically supplies all of Moxa Industrial Media Converter’s power needs.

Alarm Contact

Moxa Industrial Media Converter has one Alarm Contact located on the top panel.

For detailed instructions on how to connect the Alarm Contact power wires to the

two middle contacts of the 6-contact terminal block connector, see the “Wiring the

Alarm Contact” section above. A typical scenario would be to connect the Fault

circuit to a warning light located in the control room. The light can be set up to

switch on when a fault is detected.

The Alarm Contact has two terminals that form a Fault circuit for connecting to an

alarm system. The two wires attached to the Fault contacts form an open circuit

when (1) IMC has lost power from one of the DC power inputs, or (2) one of the

ports for which the corresponding PORT ALARM Dip Switch is set to ON is not

properly connected.

If neither of these two conditions occurs, the Fault circuit will be closed.
