safety ground connection is 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.

ROTECTION
The module has internal over-current protection to provide fault isolation in case
failure occurs of internal components or wiring. However, over-current protection
must also be provided externally, within the system installation, for the AC/DC
input of the Mainframe. Refer to the Mainframe manual for recommendations.

EVICE
The ReFlex Power™ system does not have any means to disconnect it from the
AC/DC input service. The front panel POWER switch of the Controller module in
the Mainframe does not disconnect the AC/DC input line from the modules or
Mainframe. Ensure that a suitable disconnecting device is incorporated into the
system installation, so that isolation will be provided when it is opened. The
switch or circuit breaker must be located close to the ReFlex Power™ system,
within reach of the operator, and clearly labeled as the disconnection device.
WARNING
To prevent a shock hazard, ensure that the AC/DC input disconnect device
is open, and that the safety ground conductor is connected to the rear panel
ground stud, before removing/inserting modules from/into the Mainframe.
The Mainframe backplane input power distribution remains energized
whenever the AC/DC input is connected.
