SAFETY PRECAUTIONS
1. The device must be installed by a qualified person,
2. Disconnect all power before working on the device. Don’t touch any terminal
when the power is ON.
3. Verify correct terminal connection when wiring.
4. Don’t dismantle or repair the device whether it operates normally, otherwise

:Synchronous mode;
:Asynchronous mode
:Synchronous mode; In this mode the
device works as a three phase voltage
protector with N,L1,L2,L3 as single
circuit
:Asynchronous mode : In this mode the
device works as three Individual single
phase protectors which can be
connected to three separate circuits.
Also the device can identify & stop/trip/
reset each of the three circuits
independently
i.e "N - L1" & "N - L2" & "N - L3"

FUNCTION DIAGRAMS
If a voltage fault was detected when the reset/start delay of relay is
counting, the output relay opens and faults indication LED lights up.
Voltage faults: if input voltage was detected to have returned to Hys
after tripped for voltage faults, the relay will reset automatically and
begin the counting of reset/start delay.
Current faults: After the relay tripped for current faults, it will reset
automatically begin the counting of reset/start delay.
The operating voltage and current values will be displayed on screen
when the relay is operating normally. If a voltage or current fault was
detected, the output relay opens and faults code display.
