Chapter 1: Getting Started 2
The iSmart Relay is an electronic device. For safety reasons, please carefully read and follow the paragraphs
with "WARNING" or "CAUTION" symbols. They are important safety precautions to be aware of while transporting,
installing, operating, or examining the ISMART Controller.
WARNING: Personal injury may result from improper operation.
CAUTION: The iSmart relay may be damaged by improper operation.
Precaution for Installation
Compliance with the installation instructions and the user manual is absolutely necessary. Failure to comply
could lead to improper operation, equipment damage or in extreme cases even death, serious bodily injury or
considerable damage to property.
When installing the open-board models, insure that no wiring or foreign materials can fall into the exposed
circuits and components. Damage to equipment, fire, or considerable damage to property could result.
Always switch off power before you wire, connect, install, or remove any module.
The wiring for the iSmart relay is open and exposed. For the open-board models, all electrical components are
exposed. For this reason, it is recommended the iSmart relay be installed in an enclosure or cabinet to prevent
accidental contact or exposure to the electrical circuits and components.
Never install the product in an environment beyond the limits specified in this user manual such as high
temperature, humidity, dust, corrosive gas, vibration, etc.
Precaution for Wiring
Improper wiring and installation could lead to death, serious bodily injury or considerable damage to property.
The ISmartrelay should only be installed and wired by properly experienced and certified personnel.
Make sure the wiring of the iSmart relay meets all applicable regulations and codes including local and
national standards and codes.
Be sure to properly size cables for the required current rating.
Always separate AC wiring, DC wiring with high-frequency switching cycles, and low-voltage signal wiring.
Precaution for Operation
To insure safety with the application of the iSmart relay, complete functional and safety testing must be
conducted. Only run the iSmart after all testing and confirming safe and proper operation is complete. Any potential
faults in the application should be included in the testing. Failure to do so could lead to improper operation,
equipment damage or in extreme cases even Death, serious bodily injury or considerable damage to property.
When the power is on, never contact the terminals, exposed conductors or electrical components. Failure to
comply could lead to improper operation, equipment damage or in extreme cases even death, serious bodily injury or
considerable damage to property.
It is strongly recommended to add safety protection such as an emergency stop and external interlock circuit in
case the iSmart relay operation must be shut down immediately.

Chapter 1: Getting Started 3
Examination before Installation
Every iSmart relay has been fully tested and examined before shipment. Please carry out the following
examination procedures after unpacking your iSmart relay.
• Check to see if the model number of the ISMART matches the model number that you ordered.
• Check to see whether any damage occurred to the ISMART during shipment. Do not connect the iSmart relay to the
power supply if there is any sign of damage.
Contact IMO Precision Controls Ltd if you find any abnormal conditions as mentioned above.

Chapter 1: Getting Started 4
Environmental Precautions
The installation site of the ISmart relay is very important. It relates directly to the functionality and the life span
of your ISMART. Please carefully choose an installation site that meets the following requirements:
• Mount the unit vertically
• Environment temperature: -4°F - 131°F (-20°C - 55°C)
• Avoid placing ISMART close to any heating equipment
• Avoid dripping water, condensation, or humid environment
• Avoid direct sunlight
• Avoid oil, grease, and gas
• Avoid contact with corrosive gases and liquids
• Prevent foreign dust, flecks, or metal scraps from contacting the iSmart relay
• Avoid electric-magnetic interference (soldering or power machinery)
• Avoid excessive vibration; if vibration cannot be avoided, an anti-rattle mounting device should be installed to
reduce vibration.
Disclaim of Liability
We have reviewed the contents of this publication to ensure consistency with the hardware and software
described. Since variance cannot be precluded entirely, we cannot guarantee full consistency. However, the
information in this publication is reviewed regularly and any necessary corrections are included in subsequent
editions.

Quick Start Setup
This section is a simple guide for connecting, programming and operating your new iSmart relay. This is not
intended to be the complete instructions for programming and installation of your system. Refer to other sections in
the manual for more detailed information.
Install ISMART Client Software
Install the ISMART Client Software from CD or from the free internet download at www.imopc.com
Connect Power to iSmart relay
Connect power to the Smart Relay using the below wiring diagrams for AC or DC supply for the applicable
modules. See “Chapter 2: Installation” for complete wiring and installation instructions.

Chapter 1: Getting Started 7
Connect Programming Cable
Please put the cable in connection port of two sides.
Network connection setup
1. iSmart IP address setup
When ISMART is setting for slave
>IP ADDRESS
SUBNET MASK
GETEWAY
MASTER IP
Please set IP address, subnet mask, gateway address and master IP, then click “OK” to setup iSmart network
connection
>IP ADDRESS
SUBNET MASK
GETEWAY
MASTER IP
For example, edit IP address
Please click “OK” to enter interface, move the cursor to "Set IP address" and click "SEL" to enter setting mode.
IP ADDRESS
255.255.255.255
When cursor becomes to “_”, please use "Up" and "Down" button to set correct value then click "OK" to save new IP
address, then click "ESC" to return to main menu.
IP ADDRESS
255.255.255.255
#The maximum default value is 255, if setting value is higher than 255, default value will be 255 also.

Chapter 1: Getting Started 8
2. Set IP address on PC
Click “Properties” to select your Internet protocol version
Set IP address, subnet net, gateway address
For example：
PC setup：
IP address：192.168.0.5
Subnet mask：255.255.255.0
Default gateway address：192.168.0.1

Chapter 1: Getting Started 9
Establish Communication
a. Open the iSmart Client software and select “New LAD” as shown below left.
b. Select “Operation/Link Com Port…” as shown below right.
c.
c.Select the correct Com Port number where the programming cable is connected to the computer then press the
