INVERTER

This is the output stage, the function of which is to convert the DC voltage from the RECTIFIER or from the
BATTERY into stabilized sinusoidal AC voltage. The inverter output is isolated from the input and from the batteries
by a galvanic isolation transformer. The inverter is always working; since the load connected to the UPS output is
always powered by the INVERTER (in NORMAL OPERATION)

STATIC SWITCH

This device allows in synchro transferring, automatic or manual, and in zero time, the load from a protected source
(inverter output) to a non protected source (bypass line) or vice versa.

The UPS is provided with “

BACKFEED PROTECTION”

a redundant device to prevent the backfeed of voltage to the

by-pass input line in case of an internal fault.

Maintenance BYPASS (SWMB) (Optional)

This is a Maintenance bypass switch. The UPS can be bypassed by closing SWMB and opening switches (SWIN,
SWBY and SWOUT) while keeping the load on the output powered. This operation is necessary when maintenance
operations must be carried out inside the equipment without interrupting the power supply to the load.
The Maintenance bypass switch is sized for the rated power of the UPS.

CAUTION – When the Maintenance bypass switch SWMB is closed dangerous voltages are present inside the UPS.
Great care must be taken when performing maintenance on a UPS with mains voltage present and the SWMB closed.
RPS recommends only using the Maintenance bypass for keeping your load powered if the UPS has failed. For
maintenance we recommend the use of a RPS external maintenance bypass switch. Consult the factory for more details.

follows the phase sequence

Phase L1 of the mains source must be connected to input phase L1 on all the UPS’s; all the output phases
L1 must be connected together and with phase L1 of the load. This convention must be followed for
phases L2, L3 and for the input and output neutral.
