Mounting Dimensions

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.

— 4 —

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.

— 5 —

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.

This unit is a building-in type. During installation into a

certain end equipment it shall comply with fire enclosure

request of IEC 60950/EN60950 or similar sentence.

Safety First!

Be sure to disconnect the power cord before installing

and/or wiring your MOXA Industrial Media Converter.

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:

 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. The rule of thumb is

that wiring that shares similar electrical characteristics can be

bundled together.

 Keep input wiring and output wiring separated.

 It 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.

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 consists of two middle contacts of the terminal block

on IMC’s top panel. You may 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 will explain the meaning of the two contacts used to

connect the Alarm Contact.

— 7 —

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.

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.

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.

RJ45 (8-pin, MDI) Port Pinouts RJ45 (8-pin, MDI-X) Port Pinouts

RJ45 (8-pin) to RJ45 (8-pin) Straight-Through Cable Wiring

RJ45 (8-pin) to RJ45 (8-pin) Cross-Over Cable Wiring

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).
