Slide the expansion unit that is to be detached. Detach it individually from the DIN rail. Note 1: When connecting several amplifiers, be sure to use a DIN rail and the end units. Note 2: Be sure to turn the power off before connecting/disconnecting amplifiers. Note 3: Do not remove the protective cover on the expansion connector from the outermost unit. Note 4: Do not detach several units from the DIN rail while they are connected to each other. Note 5: When several units are connected, confirm that the ambient temperature is appropriate.
