ROTECTION
The modules have internal overcurrent protection to provide fault
isolation in case failure occurs of internal components or wiring.
However, overcurrent 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.
