How To Wire A Battery Backup UPS To A 120/240 Split Phase Residential Electrical Panel

Single Phase Wiring Diagram

Battery Backup UPS (uninterruptible power supply) systems in the following table can be directly wired to either a 120/240 split phase panel (6k & 10k single phase models) or a 120/208Y 3 phase panel (10k, 15k, 20k, 30k, & 40k 3 phase models). The 6k & 10k single phase models have built in isolation transformers that create their own neutral. This allows for the installer to select and wire one of a multitude of output voltage options.

If battery power reserves will not provide sufficient backup time, the UPS can be paired with either an ATS (automatic transfer switch) or a manual transfer switch which allows the UPS to provide seamless uninterrupted bridge power to the connected loads while a generator or secondary power source comes online after utility power or the primary source fails. The above models have either "Generator Mode", "CVCF (Constant Voltage Constant Frequency) Mode", or "Wide Frequency Input", so that they will accept either grid power or generator power as the input power source depending if the optional transfer switch and generator/secondary power source is added.   

No matter what the input power source is, the critical loads (servers, computers, workstations, phones, network stack, lab instruments, etc.) will be unaffected because they are always on real-time conditioned backup power provided by the UPS.
