Consider both the operating state of the UPS and the BPM when protecting your critical loads. Failure to understand the correct bypass sequence and position may cause the critical load to be dropped. The BPM has three operating positions (see Table 1). Please refer to the installation chapter of your UPS manual for the BPM wiring diagram. Installation for models requiring hardwire connections should be performed by a qualified electrician following local electrical codes. The BPM should only be operated by an experienced user, familiar with UPS behavior and functionality. The BPM also offers output distribution in order to simplify wiring in a rackmount IT environment, potentially removing the need for a panelboard, breakers, and conduit for distribution.Īlthough the BPM is designed to be safe, the bypass can carry high levels of voltage and current. The BPM provides added reliability to Eaton uninterruptable power supply (UPS) systems by ensuring seamless, uninterrupted, no-break transfer as well as a lock-out/tag-out (LOTO) feature to ensure the greatest safety for UPS technicians and electricians.
