Safety Precautions

	 In order to prevent invasion of noise, MODBUS RTU communication cables, auxiliary
	power supply cables, and other signal cables must not be placed close to or bound
	together with power lines or high voltage lines. When lying parallel to the power lines or
	high voltage lines, refer to the following table for the separation distance. (Except the
CAUTION	input part of the terminal block)
		Conditions	Distance
		Power lines of 600 V or less	300 mm or more
		Other power lines	600 mm or more

■Precautions on preparation before use

Observe the use conditions and environment requirements for installation place.

You must set up the instrument before use. Read the manual carefully to set it up correctly. If the setup is incorrectly done, the instrument will not be properly operated.

Check the power rating of the instrument and then apply proper voltage.

■Precautions on how to use

When operating the instrument, check that active bare wires do not exist around it. If any bare wire existed, stop the operation immediately and then take appropriate action such as insulation protection.

If a power outage occurred during the setup, the instrument would not be set up correctly. Set it up again after power recovery.

Do not disassemble or modify the instrument to use. Otherwise, a failure, an electric shock, or a fire can be caused.

Use the instrument within the rating specified in the manual. If you used it outside the rating, it might cause not only a malfunction or failure of the instrument but also ignition or burnout.

Do not open the CT secondary side while the primary current is energized. When the CT

secondary side circuit is open, the primary current flows. However, the secondary CAUTION current does not flow. Therefore, a high voltage is generated at the CT secondary side and the temperature rises, resulting in insulation breakdown in the CT secondary

winding. It may lead to burnout.

When external equipment is connected to the external terminals, the instrument and external equipment must not be powered and be used after the definitive assembly on a cabinet door.

The rating of the terminal of external equipment should satisfy that of the external terminal of the instrument.
