DIN Rail Mounting
The aluminum DIN rail attachment plate should be fixed to the back panel
of the IMC-101 when you take it out of the box. If you need to reattach
the DIN rail attachment plate to the IMC-101, 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 the IMC-101 from the DIN rail, simply reverse Steps 1 and 2
above.
Wall Mounting (Optional)
For some applications, you will find it convenient to mount the IMC-101
on the wall, as illustrated below.
STEP 1:
Remove the aluminum DIN rail
attachment plate from the
IMC
-101, and then attach the
wall mount plates.
STEP 2:
Mounting the IMC
-
101 on the wall requires 4 screws. Use
the IMC
-
101, 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 plate.
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.

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 a
rea 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 an
d 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 IP54
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.
SAFETY FIRST
Be sure to disconnect the power cord before installing and/or
wiring your Moxa IMC-101.
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 the IMC-101
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 the IMC-101’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:
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. The IMC-101
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
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 IMC-101
’s top
panel.
ATTENTION
Before connecting
the IMC-101 to the DC power inputs, make
sure the DC power source voltage is stable.
Communication Connections
The IMC-101 has 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 the IMC-101’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) 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 easy to understand. 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 the IMC-101’s power needs.
Alarm Contact
The IMC-101 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) the IMC-101 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.
