You can install an optional REPO circuit that shuts down the entire parallel system using a single switch. To
install a REPO switch for a parallel system, the selected REPO command (NO or NC) contacts from each UPS
in the system must be in parallel.
To install a REPO switch for a parallel system:
1.
Verify that the UPS system is powered down and all power sources are removed. For more information,
see "Powering down the parallel system (on page
73
)."
2.
Mount the remote REPO switch. HP recommends mounting the REPO switch near the operator's
consoles or near the exit doors. For enclosure dimensions and wiring knockouts, see the REPO switch
manufacturer's installation instructions.
