Safety This manual contains following safety marks, which indicate the potential dangers. Please read carefully to learn when the dangers occur so as to take necessary method to protect the personnel and equipment. Indicates the direct injury that can lead serious injury or even death. Indicates the dangerous and unsafe operation that can lead serious injury or even death. Indicates the dangerous and unsafe operation that can lead personal injury or product/property damage. Electric shock may cause serious personal injury or even death. There is possible electric shock that may cause serious personal injury or even death upon the high voltage of transfer switch components. Please read and observe the following advices. Keep the transfer switch cabinet closed and locked. Make sure only the authorized personnel can have the key. High voltage in the cabinet may cause serious shock injury, so all the maintenance and repair concerning the transfer switch should only be done by electrician or authorized personnel. If it is necessary to open the cabinet: 1. Turn the operation selection switch of generator set to “OFF”. 2. Power off the battery charger. 3. Power off the generator or its starting battery. (Remove the negative grounding lead firstly.) 4. Power off the ATS AC power supply. If it is required by operation guide to switch off AC power on ATS, special caution for electric shock should be exercised. General precautions When operating electrical equipment, place a rubber insulation mat upon the dry wooden platform on the metal or cement base. Forbid wet dress (especially wet shoes) or wet skin surface exposed in electrical equipment operation. Jewelries are good conductors of electricity. Remove them when operating the electrical equipment. Do wear the safety glasses when maintaining the ATS. Forbid smoking around the battery. 3

1. ATS general introduction 1.1 Definition and working principle ATS is short for automatic transfer switch. It is mostly used in emergency power supply system, automatically switching the load circuit from one power supply to another (standby power supply) and insuring the continuous and reliable running of important load.

1.2 Applications (1) Switch between the grid and standby power supply (i.e. generator set) Applicable to the system of standby power supply (i.e. generator set) or one-way power grid. The transfer switch can automatically detect power fault of the grid, send start signal to standby generator set and switch the load. (2) Switch between generators Applicable to the system with several generator sets as the main power supply. If the main generator set goes wrong, the transfer switch will send start signal to the second generator set and switch the load. (3) Switch between the grids Applicable to the multiple power grids without a standby generator set. If one grid goes wrong, the transfer switch will automatically connect the load to the second one. (4) Triplicate power supply A. Applicable to the single standby power supply and dual grid system. The grid transfer switch controls the power supplied by dual grid according to the predetermined order. If power supply of both the grids goes wrong, the transfer switch will send start signal to standby generator set and switch the load. B. Applicable to the single grid and dual standby power supply system. If the grid goes wrong, the transfer switch will send start signal to the main standby generator set and switch the load. If the main standby generator set goes wrong, the transfer switch will send start signal to the second standby generator set and switch the load.

1.3 ATS switching mode (1) Open-loop switching (in-phase switching, power-off switching) Off after On is the basic switching mode: Firstly switch off the first power supply, and then switch on the second power supply. Users can monitor both the power supplies and start switch with the in-phase monitor (or sync check function) in the controller, so as to avoid the problem of out-of-phase. Application: emergency power system, regulation specified power system and optional standby power system; resistive load; small motor load. 5

(2) Delayed switching (program controlled switching) Similar to the open-loop switching. Firstly switch off the first power supply, and then switch on the second power supply after an adjustable delayed period. This adjustable period is enough for the residual voltage to attenuate before connecting to the second power supply. Application: Inductive (motor) load, recommendation of some UPS and VFD manufacturer. (3) Closed-loop switching (parallel switching) Off after On switching can make continuous power supply. Through the instant parallel of power supply (
