FAQ

• Q: What is the rated voltage of the SGMA800-3200A Series Dual Power Automatic Transfer Switch?
  • A: The rated voltage of the switch is AC400V.
• Q: In which industries can the SGMA800-3200A Series Dual Power ATS be used?
  • A: The switch can be used in various industries such as high-rise buildings, medical facilities, post and telecommunications, coal mines, ships, rail traffic, military, and fire facilities.

OVERVIEW

SGMA800~3200A series dual power ATS applies to the system which requires AC400V 50/60Hz below, rated working current 800A~3200A. Its structure is motor driven type, and there are three positions for the switch: normal (Ⅰ), spare (Ⅱ) and off (0). It can be used in the occasions where power failure is not allowed, such as high-rise buildings, medical heath, post and telecommunications, coal mine and ships, rail traffic, military and fire facilities.

This series products comply with the standard of GB GB/T 14048.11 ”Low-voltage switchgear and controlgear — part 6-1: Multiple function equipment —-Transfer switching equipment”.

STRUCTURE AND CHARACTERISTICS

SGMA800~3200A series dual power ATS adopts two-in and one-out structure, with electric key lock and mechanical padlock. Electric key lock: control the internal power supply of the switch, when the electric lock is open, the switch acts the automatic and remote operations; when the electric lock is closed, the switch only acts the manual operation. Mechanical padlock: during maintenance, pulling up the mechanical padlock to cut off the internal power supply of the switch, so the electric and manual operations of the switch will be disabled, which ensures the personal safety.

INSTALLATION AND DEBUGGING

The installation and debugging of ATS should be carried out by professionals and person who knows the switchgear, the related protections and preventive measures must be considered during operating. The wirings of main circuit must be in a way that the leads are not subjected to any pressure or force. Before installation and debugging, firstly check if the switch is damaged or has any harmful effects, meanwhile, check for loose wires may be caused in transportation; clean up the dirt, especially the dirt on the surface of insulation parts, which may be caused by package materials during transportation or storage.

When connecting the primary circuit, pay attention to the phase sequence of the two power supplies that should be consistent, while connecting the secondary circuit, it should be strictly in accordance with the wiring diagram listed on the user manual, at the same time, notice that the voltage level of power supply; switch must be well grounded during installation. Considering in personal safety and the quickness of transferring, the handle is only used for debugging, users should not use the handle to operate with load. During debugging, firstly use handle to operate, then perform the electrical operation by manual button if there is nothing abnormal, finally go to the formal running.
