The primary wiring diagram to see the picture. The control power is derived from normal power，emergency power cand N phases. Ⅰ and Ⅱ line control power AC220V connected with terminal 102~103,104~105respectively,102 and 104 are normal power and emergency power live line respective. Terminal 101,106 are acting as a signal lamp to control the power supply. Note:101 and 106 couldn’t be connected with any other lines. When above(under) input line, under(above)terminal Ⅰ and Ⅱ line A, B, C phases will be connected with copper lines or lines acting as output.
