10.3 Installation
Warning
(1) The controller and its peripheral devices should be installed on a fire-proof material.
A direct installation on or near a flammable material may cause fire.
(2) Do not install this product in a place subject to vibrations and impacts.
It may cause an electric shock, fire, or injury.
(3) Take measure so that the operating temperature of this controller and its peripheral devices are
within the range of the specifications. Also, this controller should be installed with 50mm or larger
spaces between each side of it and the other structures or components.
It may cause a malfunction of the controller and its peripheral devices and a fire.
(4) Do not mount this controller and its peripheral devices together with a large-sized electromagnetic
contactor or no-fuse breaker, which generates vibration, on the same panel. Mount them on
different panels, or keep the controller and its peripheral devices away from such a vibration
supply.
(5) This controller and its peripheral devices should be installed on a flat surface.
If the mounting surface is distorted or not flat, an unacceptable force may be added to the housing, etc. to
cause troubles.
10.4 Wiring
Warning
(1) Do not apply any excessive force to cables by repeated bending, tensioning or placing a heavy
object on the cables.
It may cause an electric shock, fire, or breaking of wire.
(2) Connect wires and cables correctly.
Incorrect wiring could break he controller or its peripheral devices depending on the seriousness.
(3) Do not connect wires while the power is supplied.
It can break the controller or its peripheral devices could be damaged to cause a malfunction.
(4) Do not carry this product by holding its cables.
It may cause an injury or damage to the product.
(5) Do not connect power cable or high-voltage cable in the same wiring route as the unit.
The wires to the controller or its peripheral devices can be interrupted with noise or induced surge voltage
from power lines or high-voltage lines and malfunction could be caused.
Separate the wiring of the controller and its peripheral device from that of power line and high voltage line.
(6) Verify the insulation of wiring.
Insulation failure (interference with other circuit, poor insulation between terminals and etc.) could
introduce excessive voltage or current to the controller or its peripheral devices and damage them.
10.5 Power supply
Warning
(1) Use a power supply that has low noise between lines and between power and ground.
In cases where noise is high, an isolation transformer should be used.
(2) The power supplys should be separated between the controller power and the I/O signal power and
both of them do not use the power supply of “rush-current restraining type”.
If the power supply is “rush-current restraining type”, a voltage drop may be caused during the
acceleration of the electric actuator.
(3) To prevent surges from lightning, an appropriate measure should be taken. Ground the surge
absorber for lightning separately from the grounding of the controller and its peripheral devices.
