2. Wiring

REQUIRED

•Always perform grounding (FE terminal).

If grounding is not performed, there is a risk of an electric shock or malfunction.

CAUTION

•Connect a power supply that meets the rating.

If a power supply that does not meet the rating is connected, it may result in a fire.

•Any wiring operation should only be performed by a qualified technician.

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

3.Precautions When Using the Unit

DANGER

•Never touch the terminals while the power is on. There is a risk of an electric shock.

•Configure the emergency stop circuit, interlock circuit and other related circuits external to the programmable controller (referred to as the PLC in this document).

Otherwise, a failure in the PLC may damage the equipment or result in a serious accident.

Never interlock the unit with the external load via the relay drive power supply of the relay output module.

CAUTION

•Before performing program change, forced output, run, stop and other operations while the unit is in operation, be sure to check the validity of the applicable operation and safety.

An operation error may damage the equipment or result in a serious accident.

•Be sure to power on the unit according to the designated power-on sequence.

Otherwise, an erroneous operation may damage the equipment or result in a serious accident.
