Assembly Instructions
1. Place the two connection lines with a minimum
cross-section of Cu 1.5 mm² between the RKW and
the operating module (max. 50 m).
2. Connect the operating module electrically.
3. Switch the RKW so that it is neutral (i.e. no current)
and connect the 250 mm long bus-interface line to
the additional module.
4. Connect the line of the data transfer to the terminal
strips 23 and 24 (pay attention to polarity) of the ad-
ditional module and the terminal strips on the trans-
former for the current supply.
