We are going to replace CDQ2B50-30DC-A73 during maintenance. What should we do to attach a D-A73 aut?

Please order the part no.CDQ2B50-30DCZ-BQ. A refreshed cylinder and two pieces of autoswitch brackets for A73 will be packaged together for shipment. If CDQ2B50-30DCZ has already been purchased, please order 2 pieces of 'BQ5-032' , which are mounting brackets for D-A73.
