Operating the UPS in this configuration is NOTrecommended and could result in unintended upstream breaker tripping and overheating ofthe 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 onUPS operation. The UPS reads the position of the switch only when powering on.13. Replace the input and output terminal block covers.14.
