4. Punch the required conduit holes in the bottom of the enclosure for
the power supply cable, coil cables, control wiring, communications
cable(s), and any additional signal wires and conduit.
5. Locate the holes in the appropriate areas of the enclosure to separate
high (greater than 30 V) and low (less than 30 V) voltages (see
Figure 2-2).
6. Install conduit.
