Wiring precautions
• Before starting the wiring work, carefully check the label on the side panel of this
unit to understand the model No. and terminal No. to carry out the wiring properly.
• For panel mount type, use an appropriate crimp type terminal lug suitable for the
M3 screw to connect the terminals. The tightening torque of the terminal screw
must be 0.4 to 0.6 N·m.
• For socket mount type, use an appropriate crimp type terminal lug suitable for
the M3.5 screw to connect the terminals. The tightening torque of the terminal
screw must be 0.78 to 0.98 N·m.
• Pay special attention so that no crimp terminals are in contact with adjacent terminals.
• For the C15T (panel-mount type), to connect 2 crimp terminals
to the same terminal screw, bend the crimp terminals before use.
• For the C15T (panel-mount type), connect wires to terminals 1-6 and 13-18 from
the left (when viewing the terminal block).

• Keep the input/output signal cables 50 cm or more away from the drive power cable
and/or power cable. Additionally, do not pass the input/output signal cables and the
drive power cable and/or power cable together through the same conduit or duct.
• When connecting this unit and other measuring instrument in parallel,
carefully check the conditions necessary for other instrument before starting the
instrumentation.
• The digital input is so designed that it is non-voltage input. A contact for micro
current must be used.
• Pass the conductor, to which the heater current flows, through the current
transformer. Additionally, carefully check that the heater current does not
exceed the allowable current level stated in the specification. If the heater current
exceeds the allowable current level, this might cause damage to this unit.
• The input of the current transformer cannot be used for the phase angle control.
• For panel mounting type (C15T), an optional terminal cover is available to
prevent electric shock. (Model No.: 81446898-001)
