The remote ON/OFF is grounded to the UPS internal signal ground and 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.
