ONNECTION
The AC/DC input connector provides a safety ground termination. The input
power cable should include a safety ground wire to connect the chassis of the
Mainframe to the safety ground of the AC/DC power source. Depending on the
installed modules, and operating voltage/frequency, the AC input leakage current
could exceed 3.5mA; therefore, a second safety ground connection is also
required. It should be connected to the safety ground stud on the rear panel of
the Mainframe.
WARNING
A separate, dedicated safety ground wire must be
connected to the Mainframe rear panel safety ground stud.
Operating the ReFlex Power™ system with the safety
ground wire disconnected could result in a shock hazard.

The ReFlex Power™ Mainframe rear panel (Figure 2-6) has connectors for
connecting to the AC/DC input service and for interconnecting multiple
Mainframes into extended systems. Connections for individual module output
power and control interface are available on the front panels of the modules.
Refer to Figure 2-6 for a rear panel view of the Mainframe.
