desired equipment against phase failure, asymmetry and phase sequence fallure on

Utilisation and Working Principle
By using the asymmetry adjustment

PROTECTION FEATURES :
1- Voltage Unbalance (Can be Adjusted
Unbalanced voltage(asymmetry) may occur when;
The mains are loaded with unbalanced
One of the 3 phases of the motor has lost In this case, some amount of voltage
which is produced by other phases wi be induced
voltage depends on both the motor type and amount of load
Output relay is making contact when a phase has been ost or an unbalanced
Phase voltage value, which is occured for any reason, is smal er than the user defined
asymetrical value If this unbalanced

Voltage asymmetry limit values can be adjusted between 5% 15% by the user or can
be disabled. Hysteresis is 30% of the adjusted asymmetry value

Precautions For Installation and
Failure to follow those instructions
Disconnect all power before working
When the device is connected to the network,
Do not try to clean the device with solvent or the like. Only clean the device
with a dried cloth.
Verify correct terminal connections
Mount device to the panel.
Electrical equipment should be serviced
