CAUTION: Equipment Damage
The termination points of the AC power conductors at S1 include a captive nut and plastic
insulator between the terminals and the panel. Ensure the length of the connection
hardware used to attach the AC power conductors at S1-2T1-, S1-4T2, and S1-6T3, does
not "bottom-out" to the plastic insulator. The depth of the hole at terminals of S1 is ½"
from the top of the tab. Failure to observe this may result in failure of the plastic insulator
and may cause a direct short to ground.
