Dress the wires as slack as possible. This keeps the noise signal on these wires from
bypassing built-in suppression. Also, do not bundle any low level signal wires with the power
wires. Refer to Table 2-10 for permissible wire bundling.
Refer to document 51-52-05-01 for additional information concerning noise interference
prevention.
