Series 7400 Single Phase 1+N UPS

Switch S7 - Inverter ON:

Pressing this switch activates the inverter and causes the load to be transferred to the inverter side of the static switch after the inverter voltage has had time to stabilise.

Switch S8- Emergency Stop:

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 is applied through a manually controller isolator; however, if the UPS input supply is connected via a circuit breaker having an electrical trip facility the emergency stop signal can be used to drive the external circuit breaker’s trip circuit.

There are two LEDs contained within the switch panel area:

LS7 Alarm:

This led accompanies the audible alarm warning when any alarm condition is initiated. The audible warning can be cancelled by the reset switch (S5) but LS7 will only extinguish after the alarmed condition has reverted to normal.

LS8 - Inverter status:

This green led situated near the inverter ON switch illuminates when the inverter is selected ON.
