NOTE The UPS will not operate if the input is wired for single-phase and the selector switch is set for
three-phase.
NOTE If the input is wired for three-phase and the selector switch is set for single-phase, the UPS will
operate on single-phase. Operating the UPS in this configuration is NOT recommended and could result in
unintended upstream breaker tripping and overheating of the input wiring, if the breaker and wiring are
sized for three-phase input.
NOTE Resetting the phase input selector switch while the UPS is running has no effect on UPS
operation. The UPS reads the position of the switch only when powering on.
