Remove the copper bars between the mains and bypass input wiring terminals. (Perform this
step only when the mains input and bypass input use different power sources.)
Properly keep the removed copper bars and bolts.

covers and then the connecting copper bars. The protective covers need to be reinstalled after the
connecting copper bars are removed.
