Note: Use solid wires, stranded wires, or ferrules to connect to the
terminals.
To maintain the withstand voltage after connecting the
terminals, insert 8 mm of exposed conductor into the terminal.

Operation Methods

Connections
Input
Wire the input to the L1, L2, and L3 terminals (3-phase, 3-wire).
Make sure the phase sequence is wired correctly. The Unit will not operate normally if the phase
sequence is incorrect.
Outputs
For a relay output, the SPDT contacts are output on terminals 11, 12, and 14. For a transistor output,
the NPN output is on terminals 11 and 14.
Do not use the transistor output for control applications. It is designed only to output a signal when an
error is detected.

Indicators
Item
Power indicator
Lit when power is being supplied. *
(PWR: Green)
Output status indicator
Lights for output (lit for normal operation)
(Output: Yellow)
• Lights for overvoltage/undervoltage error.
When the voltage exceeds the set value, the
indicator flashes for the operating time to
Alarm
indicate the error status.
indicator
• Lights for asymmetry error.
• Lights for phase loss.
• Flashes for phase sequence error.
* This indicator uses the input across L1 and L2 as the internal power
supply. It will not light unless there is an input across L1 and L2.
Setting Knobs
Item
Asymmetry rate knob
Used to set from 5% to 22%.
(ASY)
Overvoltage/undervoltage
Used to set from 2% to 30% of the rated input.
knob (OV/UV)
Operating time knob (T) Used to set the operating time to 0.1 to 30 s.
