Some machines may already have a PL321 installed. If the PL321 is installed, the existing Product Link system must
be removed prior to installing the PL522/523 .
If the machine is PL321 ready, then the mounting space and hardware that is provided will be appropriate. The
PL522/523 footprint is identical to the PL300 footprint. Therefore, the PL300 location should adequately accommodate
the PL522/523. When considering the existing PL300 mounting location, keep in mind that the PL522/523 is 12.7 mm
(0.500 inch) taller than the PL300. The height of the PL522/523 should not pose a problem for most installations.
