applied to the product.
It will cause failure of the controller or its peripheral devices.
13. Do not use the product in an environment subject to a temperature cycle.
It will cause failure of the controller or its peripheral devices.
14. Do not use in a place where surges are generated.
When there are units that generate a large amount of surge around the product (e.g., solenoid type
lifters, high frequency induction furnaces, motors, etc.), this may cause deterioration or damage to the
product’s' internal circuit. Avoid supplys of surge generation and crossed lines.
15. Do not install this product in an environment under the effect of vibrations and impacts.
It will cause failure or malfunction.
16. If this product is used with a relay or solenoid valve, they should be the surge absorbing
element built-in type.
15.3 Installation
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.
15.4 Wiring of cables/Common precautions
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.
Te 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.
