Control System Design
DANGER
◆Design a safety circuit to ensure that the control system operates safely upon power or
controller failure.
◆Do not apply this product to machines that may cause personal injuries or death,
equipment damage, or system shutdown.
CAUTION
◆When an output unit such as a relay or transistor of the controller is damaged, its
output cannot be controlled in the ON or OFF state. To ensure proper operating of
the equipment, design an external protection circuit and a safety mechanism for the
output signals related to critical incidents.
◆The controller is designed for indoor electrical environments complying with the
Class II overcurrent rating. Install a lightning protection device for the power system
to prevent lightning overvoltage on the power input terminal, signal input terminal, or
control output terminal of the controller and avoid equipment damage.
Installation
DANGER
◆Equipment installation must be performed only by professional maintenance
personnel who have been trained on necessary electrical knowledge.
◆The controller adopts the microcomputer design. Keep the controller clean and
prevent metal scraps, conductors, water, and corrosive gases or liquids from entering
it. Any noncompliance may result in a 󶍾re, a malfunction, or a misoperation. Cut o󶍽
all external power supplies of the system before you install or remove a module. Any
noncompliance may result in an electric shock, a malfunction, or a misoperation.
◆Do not install this product on a 󶍿ammable object or in an environment with overhigh
temperature. Any noncompliance may result in a 󶍾re, a malfunction, or damage.
WARNING
◆Ensure that the ventilation plane of the controller is unblocked after installation.
Any noncompliance may result in poor heat dissipation, a 󶍾re, a malfunction, or a
misoperation.
◆During installation, connect the modules to corresponding connectors reliably and
secure the hooks. Improper installation of a module may result in a misoperation, a
malfunction, or falling o󶍽.

4
Wiring
DANGER
◆Equipment wiring must be performed only by professional maintenance personnel
who have been trained on necessary electrical knowledge.
◆Before assembly, ensure that the controller and peripherals (such as the machine tool)
are properly grounded for lightning and leakage protection.
◆Cut o󶍽 all external power supplies of the system before wiring. Any noncompliance
may result in an electric shock, a malfunction, or a misoperation.
◆The rated voltage of the power system for the controller must comply with the
speci󶍾cations. If the voltage is unstable, install a voltage regulator to ensure proper
operating of the controller.
◆Take insulation measures for cable terminals to avoid a decrease in the insulation
distance after cables are connected to the terminals. Any noncompliance may result in
an electric shock or equipment damage.
WARNING
◆The speci󶍾cations and installation methods for external wiring of the equipment must
comply with local power distribution regulations. A cable with a su󶎀cient diameter
must be used for reliable grounding. For details, see the wiring descriptions in the user
guide.
◆Verify the connector type before you connect a cable. Connection to a wrong connector
or a wiring mistake may result in a malfunction of a module or external equipment.
◆Tighten the bolt on the terminal block within the speci󶍾ed torque range. Any
noncompliance may result in a short circuit, a 󶍾re, or a misoperation.
◆Do not bundle the control and communication cables with the main circuit or power
cable; instead, keep them at least 100 mm apart. Any noncompliance may result in
noise and a misoperation.
◆Use a shielded cable for input or output of high-frequency signals in application
scenarios with serious interference, to improve the interference immunity of the
system.
Maintenance
DANGER
◆Equipment maintenance must be performed only by professional maintenance
personnel who have been trained on necessary electrical knowledge.
◆Before 󶍾rst power-on, cut o󶍽 the loads of all external equipment to avoid internal
testing with the PLC and a danger to persons nearby because the motor may
immediately start upon power input.

5
WARNING
◆As a precision instrument, the controller must be installed or removed only by
maintenance personnel of the manufacturer or electrical control personnel of related
machinery factories. Familiarize yourself with the user guide to ensure safety during
operations such as running or stopping the equipment, modi󶍾cation during operating,
or forcible output.
◆Disconnect the power cable from the socket before you clean the equipment with a
wet cloth. Do not clean the equipment with liquids or detergent sprays.
◆If the equipment is unused for a long time, disconnect the power cable from the socket
to avoid equipment damage caused by excessive voltage 󶍿uctuation.
Disposal
WARNING
◆The computer is con󶍾gured with a real-time clock circuit powered by batteries.
Improper installation of the batteries may result in explosion. Therefore, use the same
or a similar type of batteries recommended by the manufacturer for replacement.
◆Dispose of retired batteries by following the instructions of the manufacturer. According
to the IEC 704-1:1982, the sound pressure in the place where an operator is located
must be less than or equal to 70 dB(A).
◆Disclaimer: The safety instructions comply with the IEC 704-1. Inovance assumes no
legal liability for the accuracy of the content.
CAUTION
◆Dispose of retired equipment as industrial waste and dispose of retired batteries by
following local directives.

6
Safety Signs
For safe equipment operation and maintenance, comply with safety signs on the
equipment, and do not damage or remove the safety labels. The following table
describes the safety signs.
Safety Sign Description
◆Read the user guide before installation and operation.
Failure to comply will result in an electric shock.
◆Do not remove the cover at power-on or within 10 minutes
after power-o󶍽.
◆Before maintenance, inspection, and wiring, cut o󶍽 input
and output power, and wait at least 10 minutes until the
power indicator is o󶍽.

1 ） Electric shock protection when using inductive load
Since no internal protection circuit for relays is designed, when the inductive load is
applied, large back EMF will be produced between contacts and arc discharge is also
caused when the inductive load stops. This may result in contact failure or contact
sag, shortening the contact lifetime. Therefore, it is recommended to use the products
with built-in relay protection circuit. For the products without built-in relay protection
circuit, an external electric shock protection circuit can be used to reduce noises and
prolong the lifetime of product.
Relay DC circuit： Connect a freewheel diode in parallel with the load. The freewheel
diode must satisfy:
① The reverse voltage is 5 to 10 times of load voltage.
② The forward current is larger than load current.
The following 󶍾gure shows the DC circuit electric shock protection when using
inductive load.
