Connecting Braking Units in Parallel
When connecting two or more Braking Units in parallel, use the wiring and connectors shown in Figure
3.16. There are connectors for selecting whether each Braking Unit is to be a Master or Slave. Select "Mas-
ter" for the first Braking Unit only, and select "Slave" for all other Braking Units (i.e., from the second
Unit onwards).
