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.
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.
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).
