REMOTE ON/OFF TERMINALS:
Use a switch to remotely toggle ON/OFF state. Non-Polarized terminals.
No external voltage is required
. We recommend using stranded UTP (Unshielded Twisted Pair) wire for
connections.
Remote ON/OFF is grounded to the UPS internal signal ground so it should be isolated from
the chassis ground to prevent any ground potentials that may cause a unit malfunction or
damage. In addition, isolate the Remote ON/OFF wiring away from high current, high
voltage, and high frequency components to prevent any magnetically coupled noise on the
Remote On/Off connections.
