Indicators
Item
Meaning
Power indicator
(PWR: Green)
Lit when power is being supplied (see note).
Relay status indicator Lit when relay is operating (normally lit).
(RY: Yellow)
Alarm Overvoltage:
indicator Red
Lit when there is an overvoltage.
The indicator flashes to indicate the error status after
the overvoltage has exceeded the threshold value
while the operating time is being clocked.
Undervoltage: • Lit when there is an undervoltage or phase loss.
Red
The indicator flashes to indicate the error status
after the undervoltage has exceeded the threshold
value while the operating time is being clocked.
• Lit when there is a phase sequence error.
Note: The input across L1 and L2 is used for the internal power
supply. Therefore, the power indicator will not be lit if there is no
input across L1 and L2.
Setting Knobs
Item
Usage
Overvoltage knob
(OVER)
Can be set between −30% and 25% of the rated
input.
Undervoltage knob
(UNDER)
Can be set between −30% and 25% of the rated
input.
Operating time knob (T) Used to set the operating time to 0.1 to 30 s.
Note: 1. Use either a solid wire of 2.5 mm2 maximum or a ferrule with
insulating sleeve for the terminal connection.
The length of the exposed current-carrying part inserted
into the terminal must be 8 mm or less to maintain dielectric
strength after connection.
For 2.5 mm2 or
smaller solid wires
For ferrules with
insulating sleeves
8 mm max.
Recommended ferrules
Phoenix Contact
• Al 1,5-8BK (for AWG16)
• Al 1-8RD (for AWG18)
• Al 0,75-8GY (for AWG18)
2. Tightening torque
Recommended: 0.49 N·m
Maximum:
0.54 N·m
