All operations about ATS installation and debugging shall be conducted by professionals or persons
knowing the switch device and protection and precaution measures must be considered during the
operation. Wiring connection of main loop must make sure leading wire is not taking any pressure or
force. Before installation and debugging please check firstly whether switch is damaged or whether
there is harmful environment effect on it. At the same time please check whether there is loose wire
resulting from transportation; clear the smudge, especially the smudge on the surface of insulating
parts. The smudge probably is caused by the packing materials in the transportation process or in the
storage process. Please make sure the phase sequences are in accordance at connecting the first
circuit; please observe the wiring connection diagram of user manual strictly at connecting the second
circuit and pay attention to control power voltage class at the same time. Ground must be well
connected on switch installation. Considering personal safety and switch changeover rapidity,
debugging handle can only be used for debugging and users are prohibited to operate on-load with
debugging handle. First use the handle to operate switch, and if nothing unusual occurs, then operate
button manually. If nothing unusual happens, then normal running can start.
