The EMC Customer Engineer must select the proper AC power connection procedure
There are three possible scenarios at the installation site regarding the connection of
customer AC power to the EMC array. The EMC Customer Engineer (CE) must select
the proper AC power connection procedure for the scenario.
1. Refer to table below which summarizes the three possible scenarios at the
installation site when you are about to connect external AC power to the EMC
array.
2. Select the procedure that applies to your situation and follow the instructions for
that procedure.
