20.Emergency Stop - housed beneath a safety cover to prevent inadvertent operation.

When the emergency stop switch is pressed it disables the static switch block entirely (so removing load power). It also disables the rectifier and inverter, and trips the battery circuit breaker. Under normal circumstances it does not remove UPS input power since this applied through a manually controlled external isolator; however, if the UPS input supply is connected via a circuit breaker having an electrical trip facility, another section of emergency power off can be used to drive the external circuit breaker’s trip.
