2. About wiring

REQUIRED

•Always perform grounding (FE terminal).

If grounding is not performed, there is a risk of electric shocks and malfunctions.

CAUTION

•Connect power supply that meets rating.

If a power supply that does not meet rating is connected, fire may be caused.

•The wiring operation should be performed by a qualified personnel.

If wiring is performed incorrectly, it may result in fire, damage, or electric shock.

3. Precautions when using the unit

DANGER

•Do not touch the terminals while the power is on. There is risk of electric shock.

•Structure the emergency stop circuit, interlock circuit, etc. outside the programmable controller (hereinafter referred to as PC).

Damage to the equipment or accidents may occur due to failure of the PC.

However, do not interlock the unit to external load via relay drive power supply of the relay output module.

CAUTION

•When performing program change, forced output, RUN, STOP, etc., while the unit is running, be sure to verify safety.

Damage to the equipment or accidents may occur due to operation error.

•Supply power according to the power-up order.

Damage to the equipment or accidents may occur due to malfunctions.
