1.5The protector should be installed in a dry, ventilated, dust-free, and free of harmful gases, away from magnetic fields and vibrations. It should be vertically fixed on the distribution box or wall for easy operation.

2.Usage

2.1 Power transmission

Place the power switch of the protector in the 'ON' position, and the 'Close' indicator light will start flashing (indicating a waiting state for closing). The electric closing mechanism of the protector will operate. When the closing is in place, it will be in the normal closing state, and the 'Close' indicator light will remain on.

2.2 close electricity

Set the power switch of the protector to the off position, trip the protector, and turn off the main circuit.

2.3Leakage over limit tripping test:

Press the 'Leakage Test' button,protectorIt should be able to trip, the leakage indicator light is on, the closing indicator light is off, and it exceeds the limit5In seconds, the [Close] indicator light starts flashing (the electric closing mechanism is running and in a closed waiting state), indicating that the electric closing mechanism is in operation20～60The automatic closing is completed in seconds. After the closing is in place, the leakage indicator light goes out and the closing indicator light remains on.

2.4 Setting of leakage action value:

Manual adjustment and automatic adjustment can be selected as needed

According to the magnitude of the leakage current in the circuit, the leakage action value level of the protector can be manually set, or the leakage action value can be automatically set to levels I, II, and III; According to different specifications,The leakage current of each gear corresponds to: gear I:200mA Grade II:500mA Grade III:800mA. (Optional upon request)

Press the 'Leakage Setting' button to set the gear, and continuously press the 'Leakage Setting' button to set the gearI gear → II gear → III gear → cyclic conversion; Press and hold【 Leakage setting 】 Enter automatic gear setting within 3 seconds.(When)The gear indicator light is always on for a certain gear, indicating a manually set fixed gear. When the gear indicator light flashes, it indicates an automatic gear. If the gear is fixed, the power protection device has a gear memory function when turned off and turned on after power failure, and the gear remains the same as the original gear; If the automatic gear is turned off and then turned on, or if there is a power outage, the power protection device will automatically set the gear based on the leakage of the power line.

2.5This protector cannot automatically close due to overload or short circuit tripping. The power switch of the leakage protector needs to be turned off and reconnected before power can be restored.

2.6 The auxiliary power supply used in the internal electronic circuit of this protector isNPile and1Pile, if used for three-phase power protection or specifically for single-phase protection,NThe pile must be connected to the neutral wire,1The pile must be connected to the phase line, otherwise it cannot be powered on or manually closed without leakage protection.

2.7Press and hold the 'Alarm Start' button when power outages are not allowed or when power must be supplied due to leakage faults at inspection stations5In seconds, the alarm function is activated, and the [Alarm] light is on. At this time, only the [Leakage] indicator light is on when the leakage exceeds the limit, without tripping. The use of this feature must be approved by the local power department. After entering the alarm state, press and hold the 'Alarm Start' button again5Restore the leakage tripping function in seconds.

2.8The opening and closing indicator block is used to indicate the opening and closing status of the protector.

2.9 When the leakage tripping does not require automatic reclosing function, or when the internal closing motor is damaged, manual closing can be used, and an Allen wrench can be used to press the orderTurn the device clockwise to the closed state and stop (when the indicator block is "closed"). If manual opening is required, turn the device clockwise again to the open state and stop. If manual closing is required again, the protector must be turned on[Power switch]Re open and close once, then turn the device clockwise until it is in the closed position and stop.

2.11When the circuit breaker trips, the digital display will flash to show fault information

aLeakage fault tripping

Display fault current and tripping phase alternately, whileThe leakage indicator light is on, and the closing indicator light is off.

Example: If L345 → - AA - is displayed, it indicates that this trip is a leakage trip, with a fault current of 345mA and A-phase leakage. If - Cd - is displayed, it indicates a surge leakage trip.

bUnder overvoltage tripping

Trip display -9Y - indicates undervoltage tripping, and the [closing] light is off at the same time. After the power supply voltage returns to normal, the circuit breaker automatically closes and supplies power.

cLoad control tripping

The digital display flashes and alternately displays the load current values of each phase before tripping, while the overcurrent indicator light is on.

2.17Load control current regulation method

Continuously pressing the 'Function Selection' button will display 'FXXX' on the monitor”At this time, "XXX" represents the negative control current value. First, press and hold the "Function Selection" button, then press the "Leakage Setting" button. Each time you press the "Leakage Setting" button, the load control value changes once until it reaches the desired value. Release both buttons and wait for a period of time before automatically confirming.
