Nomenclature
Front
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.
Indicators
*
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.

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.

Power indicator
(PWR: Green)
Lit when power is being supplied.*
Output status indicator
(OUT: Yellow)
Lights for output (lit for normal operation)
Alarm
indicator
OVER: Red
• Lights for overvoltage error.
When the input exceeds the overvoltage
value, the indicator flashes for the operating
time to indicate the error status.
• Flashes for phase loss.
UNDR: Red
• Lights for undervoltage error.
When the input exceeds the undervoltage
value, the indicator flashes for the operating
time to indicate the error status.
• Flashes for phase loss.
• Flashes for reversed phase error.
Item
