Page 8: System Overview
2 System Overview 2.1 Description A Static Transfer Switch (STS) provides seamless switching between two power sources to provide interrupted power to a critical load. The STS continuously monitors the supply sources for failure or degeneration and switches automatically to the alternate source if the load will be affected. The break in the supply transition is so short that it is not seen by the critical load. -

Page 21: Settings
The settings should not be changed unless the user has a full understanding of the consequences. Consult Static Power prior to changing any settings. All STS settings always must be wider than the source that is supplying the STS otherwise the STS will become unstable and the load could be compromised. -

Page 39: Maintenance Bypass
7 Maintenance Bypass 7.1 Overview Maintenance bypass mode allows the load to be connected to one supply without going through the power circuit of the STS. In this mode, transferring the load to an alternate supply is not possible. The maintenance bypass mode should only be used to select the presently operating source. -

Page 44: Load Fault
8.2 Load Fault In case of sustained high current output load faults, the STS will inhibit a transfer to the alternate supply even if this means degradation or loss of source supply. It is therefore imperative that you ensure that the discrimination with downstream and upstream protective devices ensures that the downstream protective device always clears the fault first. -

• Inspect cable / plug connections for overheating. • Units with fans need their fans changed every 3-5 years. This may need to be sooner if the environment is bad. Please contact Static Power for help with troubleshooting and parts replacement. -
