The UPS is now in bypass. To return to normal operation, reverse the process.
The 30M/40M/60M sux in the distribution center part number indicates an integral 3
breaker maintenance bypass in the bottom of the cabinet. The feature enables make-
before-break isolation of the UPS from the critical load for maintenance of the UPS.

The drawing below shows bypass utility input A, UPS isolation input B
, and UPS isolation output C termination points. The bypass output Dis
prewired to the distribution panel, which reduces installation time. Use
the attached table as a wiring guideline subject to NEC and local codes.
Flexible cable and conduit is recommended for ease of installation.
Access panels are located on the side and rear of the bypass enclosure for
access to termination points.
