Logical input	Impedance 1.8 KΩ, power supply +24V
Start frequency	Frequent or infrequent start available, start is advised not to exceed 10 times each other
Protective function	Phase failure, overcurrent, short circuit, SCR protection, overheat, phase current unbalance, wiring and inner fault
IP	IP00, IP20
Cooling type	Natural cooling or forced air cooling
Installation type	Wall mounted
Environmental condition	When sea altitude is above 2,000m, soft starter should be derated for use. Ambient temperature: -25-+45°C Relative humidity: less than 95%(20°C±5°C) Free of flammable, explosive and corrosive gas or conductive dust. Good ventilation for indoor installation and vibration is less than 0.5G

2.Installation direction
To ensure that soft starter has good ventilation and heat dissipation conditions during operation, soft starter should be vertically mounted.

3.Basic wiring diagram
Soft starter's terminals 1L1, 3L2 and 5L3 are connected to three-phase power supply and terminals 2T1, 4T2 and 6T3 connected to electric motor.
Soft starter's detection of phase sequence can be determined by parameter setting. When bypass contactor is used, one end of contactor is connected to terminals 1L1, 3L2, 5L3 of soft starter and the other end connected to terminals B1, B2, B3
