Frequency: 50Hz, 60Hz ± 2%
Applicable motor: Squirrel-cage asynchronous motor and synchronous motor
Starting frequency: Started frequently, recommended frequency less than 10 times per hour.
Protection rating: IP4X
Cooling mode: air cooled
Installation position: Indoor
Service environment: derated if used in places 1500 meters above sea level
Ambient temperature: -25~ + 45° C
Relative humidity: Below 95% (20 ° C ± 5 ° C), without condensation
Free of flammable, explosive, corrosive gas, conductive dust, properly ventilated, with vibration less than 0.6G
Working principal:
CPU controls the SCR to conduct phase angle trigger control, lowering the voltage on motor, then controls the voltage on motor and increases the motor torque of the smooth current until motor runs in full speed. The above way of starting can lower the inrush current of motor, reducing the impact on power grid and motor itself. Meanwhile, it also reduces the mechanical impacts on motor loading device, prolonging device service life and reducing motor breakdown.

Protection level of thermal overload of motor
The thermal overload protection of electric motor is reverse time limit overload protection. It is used to protect the motor by estimating the internal heat generated by the motor in the process of starting or running with a scientific calculation method. The mathematical model is established referring to IEC60947-4-2 standard, JB/T 10613-2006 standard and the performance characteristics of AC asynchronous motor in China. The overload protection curve of the starting power motor is drawn in the coordinate system according to this mathematical model, which is divided into 20 protection levels, as shown in the figure below. Level 1~8 is used in the thermal
overload protection of motor operation and the factory default value is 3; Level 9~16 is used in the thermal overload protection of motor start and the factory default value is 0 (close protection; no matter what kind of start mode, there is already protection on startup time); Level 17~20 is standby. When the thermal overload of motor does not reach the protection threshold at the start and operation process, and the working current recovers to the rated current, the heat integral constant can be restored to its initial state within 3 minutes. If the thermal overload of the motor exceeds the protection threshold, the soft start enters the protection state.

Installation Instructions
Installation of HV soft starter
4.1 Precautions for installation
on the base of the trench;
4.1.5
The reasonable installation can ensure the normal operation and service life of the equipment under the
conditions as follows:
4.1.1 Avoid installation in places with corrosive gases and metal dust;
4.1.2 Avoid installation in direct sunlight;
4.1.3 Take measures to prevent liquid from entering the inside of the device;
4.1.4 To obtain desirable ventilation and heat dissipation conditions, HV soft starter should be installed vertically
There is enough space for heat dissipation around the HV soft starter. The front and rear doors of the cabinet
can be opened for maintenance; keep the rear door of the cabinet and the wall at a fixed distance.
