A maximum of four UPS5000-E-200K-SM/FMs and UPS5000-E-300K-SM/SMTs can be
connected in parallel. Cable connection principles for two UPSs connected in parallel are the
same as those for four UPSs connected in parallel. The following describes how to connect
cables for four UPSs connected in parallel.
Procedure
Step 1 Connect the parallel ports on the UPSs using parallel cables.

Figure 3-86 shows the topology diagram for the N+X parallel system and Figure 3-87
