[Design Precautions]

WARNING●Configure safety circuits externally to ensure that the entire system operates safely even when a fault occurs in the external power
supply, the programmable controller, or the FA Goods products. Failure to do so may result in an accident due to an incorrect
output or malfunction.
(1) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting operations (such as
forward/reverse rotations or upper/lower limit positioning) must be configured externally.
(2) Outputs may remain on or off due to a failure of a component such as a relay, transistor, and triac in an output terminal
module. Configure an external circuit for monitoring output signals that could cause a serious accident.
●In an output circuit of an output terminal module, when a load current exceeding the rated current or an overcurrent caused by aload short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such asa fuse.
●Configure a circuit so that the programmable controller is turned on first and then the external power supply. If the external power
supply is turned on first, an accident may occur due to an incorrect output or malfunction.

[Design Precautions]

CAUTION●Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of100mm (3.94 inches) or more between them. Failure to do so may result in malfunction or failure due to noise.
●When using a terminal block conversion module for a high-speed counter module, do not install the control lines or communication
cables together with the main circuit lines or power cables. Keep a distance of 150mm (5.91 inches) or more between them.
Failure to do so may result in malfunction or failure due to noise.
●Keep a distance of 100mm (3.94 inches) or more between a thermocouple or RTD (Resistance Temperature Detector) and themain circuit line or AC control lines. Also, keep the thermocouple or RTD away from a circuit that includes harmonics, such as ahigh-voltage circuit and a load circuit of an inverter. If not, the thermocouple or RTD is more likely to be affected by noise, surges,
and induction.
●At power-on or power-off, a voltage may occur or a current may flow between output terminals for a moment. To use an analog
signal converter or analog terminal block conversion module, start the control after analog outputs become stable.
●Do not place an analog signal converter or analog terminal block conversion module near a device that generates magnetic noise.
●When a device such as a lamp, heater, or solenoid valve is controlled through an output terminal module, a large current(approximately 10 times greater than normal) may flow when the output is turned from off to on. Therefore, use an output terminal
module that has a sufficient current rating.

[Installation Precautions]

WARNING●Shut off the external power supply (all phases) used in the system before installation. Failure to do so may result in electric shock
or damage to the products.
