    Hello Guys, not sure if any1 of u have experienced but i need your inputs...i am t-shooting the powerware plus18 ups...the prolem is evey time i power-up the CB1 (main input circuit breaker), the CB1 itself trips...but when i tried disconnecting the shunt trip cable from the pcb board (dont know board's name) to the CB1, then it'll not trip. The "board" might have some problem or this board act like a system monitor...This is like a tough job to me but to those who have experience, please share some tips..thanks.
