Most smaller drives have knock-outs for conduit entry. Larger drives provide a
removable conduit entry plate. It is important to remove this plate before drilling or
punching it.
When a drive is supplied with an auxiliary enclosure, it generally is necessary to drill
or punch conduit entry holes in the auxiliary enclosure. It is important to ensure
that metal chips or filings don't get into any of the devices which are housed in the
auxiliary enclosure.
