Run the AC power wires through the “high voltage” conduit described earlier in this chapter.
Bring the wires for AC power, the emergency stop, and top stop circuits, and for the input
check circuit through the top right knockout. No. 16 wire (No. 14, if local codes require it)
with a minimum 75°C temperature rating is recommended for these circuits. To wire AC
input terminal block, follow these steps.
1. Find the AC terminal block at top right corner of the back wall of the enclosure (see
