Safety Precautions
Please observe the following safety precautions when installing and using the ioThinx 4510 Series:
DANGER
Never work on the device while the power source is switched on. Disconnect all power sources to the device
before performing installation, repair, or maintenance work.
DANGER
Disconnect the power when you want to remove or replace components, or disconnect equipment unless the
area is known to be free of ignitable substances.
•
If you connect or disconnect the Removable Terminal Block when field power is applied, an electrical arc
can occur. This could cause an explosion when installed in hazardous locations. Ensure that power is
removed or the area is nonhazardous before installation.
•
If you connect or disconnect wiring while the power is on, an electrical arc can occur. This could cause
an explosion in hazardous environments. Ensure that power is removed or the area is nonhazardous
before installation.
•
Do not disconnect the unit unless the power has been disconnected or the area is known to be
nonhazardous. In a hazardous area, the unit must be powered down before removing it.

Wiring System and Field Power
Wire range: 12 to 26 AWG (Ferrule diameter: 2.0 to 0.4 mm)
Wire strip length: 10 mm
Unit: mm (in.)
The device requires two sets of power inputs. One is for the system (internal logic circuit), and the other is
for field I/O circuits.
NOTE
All I/O points have 3 kV VDC
or 2 kVrms isolation with the system. We recommended using different power
supplies to ensure that the system power and field power are isolated from each other.
System Power
This device requires a 12 to 48 VDC system power input. The system
power
powers this device and the expansion modules via an internal
bus, which is galvanically connected to the system power supply.
The amount of system current required to support an expansion module is 1 A. If more modules and more
power consumption is needed, an additional power module (45MR-7210) is required. Below is an example:

ioThinx 4510 Series Hardware Installation
3-3
•10 x 45MR-1600 (59.4 mA) = 594 mA
•5 x 45MR-3810 (187 mA) = 935 mA
The total system current is 1.594 A, which is greater than 1 A. Therefore, an additional 45MR-7210 is
needed.
NOTE
Install the 45MR
-7210 to the left hand side of the module where the power consumption would be
exceeded.
NOTE
To avoid damaging your devices, r
eset all power supplies connected to this device and 45MR-7210 modules
at the same time
.
NOTE
Click the following link to see how many 45MR
-7210 power modules you will need to support your ioThinx
4500 series application:
http://iothinxcalculator.moxa.com
Field Power
This device provides
a field power input of 12/24 VDC that passes
directly through the expansion modules and provides a maximum
current output of 2 A.
NOTE
The 12/24 VDC field power supply can be connected directly to 45MR modules. If more connection points
are needed, purchase
45MR-7820 (8 x FP+ and 8 x FP-) modules.
Wiring Ethernet Ports
The maximum cable length of a 10/100BaseT connection is usually stated as 100 m (350 feet), but the
actual limit for your application could be longer or shorter depending on the amount of electrical noise in the
environment. To minimize the amount of noise, Ethernet cables should not run parallel to power cables or
other types of cables that generate electrical noise. The following diagram and table shows the pin
assignments for the RJ45 Ethernet ports:

5 GND GND GND
NOTE
Connect the signal common
pin (e.g. GND pin on the serial port pin assignment) between each of the serial
device units. For insulated wire (shielding cable)
that is used to reduce electrical noise, connect the cable
shield drain wire to the chassis ground.
NOTE
To ensure that wi
res are securely connected to terminal block connectors, strip 7 to 9 mm of insulation off
the ends of the wires before connecting them to the terminal block
.
Grounding the Unit
This device has two ground pins. One pin is for system power and the other pin is for field power.
Connecting the System Power Ground
The system power ground connector is at the back of the unit. Once the device has been installed on a DIN
rail, the system power ground connector will connect to the DIN rail.

CAUTION
For surge protection, c
onnect the DIN rail to earth ground.
Connecting the Field Power Ground
Connect the field power ground pin ( ) to your field power ground.
CAUTION
Be sure to
note the maximum possible current for each power wire and common wire. Observe all electrical
codes dictating the maximum current allowable for each wire size. If currents exceed the maximum rating
,
the wires will overheat
, which could cause serious damage to your equipment. For safety reasons, we
recommend
using 2 mm diameter wire to connect to the power supply (e.g., 12 AWG).

Mounting the Unit
In this section, we describe how to mount the device on a DIN rail and how to unmount the device from a
DIN rail.
DANGER
Never install the device while the power source is switched on
.
Installing the Unit on a DIN Rail
Take the following steps to install the unit on a DIN rail.
Step 1: Hook the mounting clip of the unit onto the DIN rail, and then lower the clip onto the DIN rail. At
least 55 mm of space above the DIN rail should be kept free to ensure that the installation can be done
correctly.
Step 2: Push the unit towards the DIN rail until the end of the mounting clip snaps into place.
INFORMATION
When the I/O module is inserted into the correct position, the connection between the internal bus
and the previous module is established.

Removing the Unit from a DIN Rail
Take the following steps to remove the unit from a DIN rail.
Step 1: Use your finger to pull the release tab on the lower part of the module.
Step 2: Press the release tab (item 1 in the figure) and then remove the CPU module from the DIN rail
(item 2 in the figure).
NO
TE
Disconnect all connections,
including Ethernet, serial, and power cables, from the device before removing
the device from the
DIN rail.
