(9) Do not install the Product close contact with the heating element.
(10) Use a power supply that will reach the rated voltage within 1 second after the power is turned ON.
(11) Do not install the Product near equipment that generates high frequencies or surges.
(12) Make sure that the setting values registered in the Product match the specifications of the load and
special CT that are actually used.

• To use the Product, install it as an embedded device within a control panel.
• To use the special CT, install it in the same control panel as the Product with a sufficient clearance
from other devices.
• For the special CT, use one with –C suffixed to the model.
• For the operation power supply and voltage inputs, use recommended fuses that are externally
installed.
• Use the voltage and CT inputs under conditions specified for the measurement category.
• The maximum temperature of the terminal block is 65°C. Therefore, use wires with a rated
temperature of 65°C or higher.
• Select wires in accordance with Table 2 so that the case temperature of the special CT will be
65°C or less.
• For the wire passing through the primary side of the special CT, use an insulated wire with basic
insulation or higher degree of insulation that conforms to the rated voltage and size of the AWM
(Appliance Wiring Material) wire in Table 1.
• Table 1 below shows the nominal voltage and measurement circuit connections available for each
measurement category in the Main Power Supply System Configurations. Do not use the device
under conditions that exceed this category and conditions.
