Notes:
①A set of automatic power transfer system comes standard with two GTW1 universal circuit breakers, one automatic transfer controller one set of control cables, and one set of interlocking mechanism. Among them, the voltage of the universal circuit breaker controller power supply, shunt release, closing electromagnet, and energy storage motor should all be AC230V.
②When the user orders without any requirements, the controller is selected as M-type, and the default setting value at the factory is:
a)Set the long delay Ir to 1.0 In and the action time of 1.5 Ir to 15 seconds
b)Set the short delay Is to the value of 8lr and the timing limit to 0.4s
c) Instantaneous li set at 12In
d) Ground fault lg set at 0.4ln, action time 0.4s
