Re: WA6-30N High Voltage Enable

Are you you enabling (shorting) the safety interlock before plugging in the AC power?

Section 3-1 in the manual shows the steps you need to follow.
Section 4-4 states that if the interlock is opened the output is cut off until the AC power is removed and turned on again.
