The terminals EPO stand for emergency power off These mushroom switches are sometimes a little tricky to get right as not many people understand control terminology well. make sure you use deep and large boxes as the mechanical parts to these switches tend to be rather large. It may pay to use a 2 gand deep with a cover punched with a keyed 1" trade size hole for the actuator button check to see if you need momentary contact or maintained contacts. The grounding central bar was under the table in the pit so leave the grounds a little long so you can work on them outside of the pi t then place it back and anchor it with 2 bolts
