CLE Three Phase Voltage and Current Protector Instruction Manual
SAFETY PRECAUTIONS
- The device must be installed by a qualified person.
- Disconnect all power before working on the device. Don’t touch any terminal when the power is ON.
- Verify correct terminal connection when wiling.
- Don’t dismantle or repair the device whether it operates normally, otherwise no responsibility is assumed by producer and seller.
- Never use the device at the site which can be invaded by corrode gas. strong sunshine light and rain.
- Clean the device with a dry cloth.
- Fail to follow these instructions will result in serious injury or death.

OPERATING RANGE
3 PHASE VOLTAGE AND CURRENT PROTECTOR
Please read complete instructions prior to installation and operation of the device.
FRONT-FACE PANEL
RESET/START delay display
When the voltage is higher than the set value, the protector will automatically reset, and the set value must be more than the under-voltage protection value by more than 5V.
Switch on/off manually
Indication for incorrect phase sequence
Display L-1L3-L-2 on the phase sequence protection function.
lndrcat1on of continuous over current fuels
Display for continuous over rnrrenl faults after reset/stay’s delay is owe. Over current faults times is mora than preset times.
- Disconnect the overload device
- Start the really after reset manually
OPERATING INSTRUCTIONS
- If a village fault was detected when the reset/start delay of relay Is couching, the output relay opens and faults Indication LED lights up.
- 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 fault Indication LEDs light up
- Voltage faults: input voltage was detected to have returned to His after tripped for voltage faults. the relay will reset automatically. During the counting of reset/start delay faults indication LEDs go out and the operating Voltage and cement values flash on screen.
- Current faults: Alter the relay tripped for current faults will reset automatically. During the counting of reset/start delay. Fault indication LED goo’s out. The operatizing voltage and current values flash on screen.
