Parallel/Series Connection
More than one unit of the same model can be connected in a parallel or series configuration.
Table 3.2 below shows the total number of units that can be connected in each configuration.
The power supplies can be set up in master/slave mode so that the master unit can control all
other power supplies in the parallel or series connection.
Note: Master/slave configurations and RS-485 connections must be properly set up prior
to controlling the power supplies in parallel/series connection. However, RS-485
does not have to be set as the Communication interface for master/slave operation
to function.

9115 and 9115-AT 3 units (240 V Max) 3 units (180 A Max)

Connecting more units in series/parallel than specified in the table above can cause
damage to the power supplies and void the manufacturer’s warranty.
