Ac/Dc Input Isconnect Evice - Ametek Elgar ReFlex Power Operation Manual

ReFlex Power™
AC/DC I
3.4.7
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. In
multi-Mainframe systems, each Mainframe has an independent AC/DC input, so
the input disconnect device should simultaneously open/close the input
connection to all assets comprising the system.
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.
