Usage Method

Switch Function

1.Automatic function: when normal power supply is of, the switch transfers the circuit to Backup power supply; when normal power supply is recovery,the switch would transfer circuit to Normal power supply.

2.Forced recovery "0" function: start "0" button, the switch would cut two power supplies.

3.Remote control function: remote control, push "Ⅰ" button to start the normal power supply, Push "Ⅱ" button to start back up power supply; Push "0"button to cut off two power supplies.

4.Please choose the switch function,and connect according to needs.

5.Please mention the model No..Specification and needed functions.

Switch Control Type and Relevant Function

1.Ⅰ type:Automatic type.

2.Ⅱ type: Automatic, Forced "O",remote control, With generator.

3.Ⅲ type: Phase loss detection protection,automatic, Forced "O", remote control, With generator.

4.Automation: Self-throwing and self-reset, when normal power supply stops or defaults phase, switch transfers circuit to standby power supply.And when normal power recovers, switch transfers circuit return to normal power supply.

5.Forced "0":when there is an emergency or device detection, start Forced "0" self-lock button,switch turns to "0" position and cut two circuits.

6.Remote control: press "Ⅰ" position button,then normal power supply starts working;press "Ⅱ"position button,then standby power supply starts working.

7.With generator:when normal power supply stops or defaults phase,then it gives the signal to start generator. When the power is turned on, the switch will automatically switch to the power supply.And when normal power supply recovers, switch returns the circuit to normal power supply,and stops the generator.

8.Phase loss protection:detect and protect normal power supply phase-loss.

Using Instruction

1.Nonprofessional installation and Unauthorized opening is forbidden;

2.Please read this instruction to avoid improper using.

3.Switch interior control power supply rated voltage is 220V, from c1 of normal power supply,N1 and C2,N2 of standby power supply .0nly it is between 85% to 110% of rated control voltage, it could work normally.

4.Switch input terminal power supply should have overload protection for interior circuit board and control motor to avoid high voltage damage.

5.Switch output terminal should have short-circuit protection against high circuit damage.

6.When installing,please turn off Electrical key lock, and turn the switch to "0" position.

7.When connecting, please distinguish A, B, C, N of power supply input line, and connect to relative poles.

8.Before powering on, please check whether C.N voltage is in the 85% to 110% rated control voltage range,then turn on the electrical lock

9.Please keep the electrical key and handle separately in case of accident.
