all power is off to prevent accidental contact with high energy and
injury to personnel.

There are cables connected at the rear of the Site Controller. Slide out the Site
Controller carefully, tag and disconnect ribbon cables at the rear.
Remove the Site Controller cover. Unscrew 19 screws securing the cover and slide it off gently
to avoid damage to components installed on the board (the cover can harm the springs on the
