Issue:
Can I use the IO (Input Output) Wiring Block of my Symmetra LX on my Smart UPS Modular Ultra UPS

Product Line:
Smart UPS Ultra Modular UPS Offering - 208/240 North American Region

Answer:

The Symmetra LX input/output wiring block SYAFSU14 is only compatible with a 15K Smart UPS Ultra Modular UPS Frame SRYLF15KRMT. A Symmetra 16K frame is rated at 100 amps to the upstream breaker like a Smart UPS Ultra Modular 15k Frame SRYLF15KRMT. However, the Symmetra 8K frame is only rated at 50 amps at its upstream. To follow all regulations and safety standards, we must assure that we follow the correct wire gauge and breaker ratings for the target UPS to be installed. Electrical installation of the unit must be done by an electrician or qualified personnel.

Please note on the images below, that the 20k frame of the Smart UPS Ultra Modular is rated for 125 A.

Also, the wiring block of the Smart UPS Ultra Modular 20K frame SRYLFSU7 is completely different from the 15K counterpart. The 15K frame has the exact lug size from a Symmetra LX I/O Tray.
