UPS maintenance bypass cabinet integrates three functions
This UPS bypass cabinet system enables IT and facility managers to integrate power transformation, power distribution and maintenance bypass into a single cabinet. This three-in-one cabinet complements a rack-based 60 kVA UPS parallel system, and is designed to allow the transfer of power to full system bypass to perform service, testing and maintenance on up to a full rack of UPS units without interrupting power to the critical load.
The Powerware BladeUPS Maintenance Bypass Cabinet (MBC) enables IT and facility managers to integrate power transformation, power distribution and maintenance bypass into a single cabinet. This three-in-one cabinet complements a rack-based 60 kVA Powerware BladeUPS parallel system, and is designed to allow the transfer of power to full system bypass to perform service, testing and maintenance on up to a full rack of Powerware BladeUPS without interrupting power to the critical load.
Instead of having a separate power distribution unit or step-down transformer, distribution cabinet and bypass cabinet, this system combines the convenience and simplicity of all three functions in one factory-tested box. The integral maintenance bypass is a mechanical way to bypass the internal components of the UPS while still sending utility power to the load. If the UPS must be repaired internally, it can be completely isolated from utility power and a technician can safely perform service without voltage present.
The unit uses a TP-1 transformer, which meets the U.S. Department of Energy standard for the Energy Star program, to step down utility power from 480 V to 208/120 V to provide electrical isolation and appropriate input voltage for the UPS modules. With high efficiency, even at low loads, the transformer yields significant savings in utility costs.
Additional features include:
• Integrated power distribution with two 42-pole Cutler Hammer panelboards for easy installation of additional breakers in the field
• Multi-function design that integrates electrical isolation, voltage transformation, electrical distribution and maintenance bypass; simplifies the data center architecture and conserves floor space, compared to separate maintenance bypass and power distribution systems
• Free-standing design that harmonizes with other data center equipment and easy installation and use with flexible access and deployment options.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
