Wiring Diagram
1. Set the rated voltage range control knob.
The position of this knob is only taken into account on energisation of
the device.If the switch position is changed while the device is opera-
ting, all the LEDs fl ash, but the product continues to operate normally
with the vol tage selected at the time of energisation preceding the ch-
ange of position.
The LED's return to their normal state if the switch is returned to the o-
rigin al position selected prior to the last energisation.
2. Set operation threshold value.
3. Set the time delay interval to 0.1s...10s so as to prevent operation in
case of transient fault.
4. In case of voltage failure, the relay would be disconnected at the exp-
iration of set time delay interval.
5. If the relay detects voltage failure during electrification, the output re-
lay would be kept in off-state.
6. The measured voltage U <Un*70% indicates open phase fault, and
the minimum open phase voltage is 165V.
7. When ZHRV5-03 phase sequence is correct, the output relay wouldcl-
ose and the R/T LED would go ON at input voltage (>176V);when ZH-
RV5-03 detects phase sequence error and the failure of one or m-
ore phases,the output relay would be disconnected,and the R/T
LED does not go ON.
8. In case of open phase fault at power input terminals L1 and L2, the fu-
nction LED would not make indication.

1. This product shall be installed, operated and maintained by professional personnel.
2. Whether or not the product functions normally, user shall not dismantle or repair the said product without permission, and we shall not assume any respon-
sibility for the accident as a result thereof.
3. Please refer to the wiring diagram in Operation Instructions when arranging wires.
4. Never place power input line in the same conduit with other wires with heavy current. Please use shielded wire if necessary so as not to bring about interfer-
ence that may influence the normal operation of relay.
5. Do not use this product in areas with dust, corrosive gases and with exposure to direct sunlight and rain.
6. Never use this product in medium with explosion hazard and with gases that may corrode metals and destroy the insulation, and do not use this product in a space
with conductive dust.
7. Please store and use this product at rated supply voltage and stated temperature, height above sea level and humidity.
8. Failure to follow these instructions can result in death, serious injury, or equipment damage.
9. The warranty period of this product shall be 18 months under normal use.
