Removing the Knockouts
All S300 expansion enclosures have metal knockouts around the outside edge. Use
the knockouts to run your wiring to external devices and other S300 expansion
enclosures. Prior to mounting the panel, determine which side or sides of the cabinet
to run the wiring through. Remove the knockouts using a hammer and a punch.
Remove only the knockouts required for wiring.
