Vertiv MP2-115A Bypass Switch

Overview

The Vertiv MP2-115A is a 2U rackmount bypass switch designed to facilitate maintenance or replacement of compatible Liebert 120V UPS units without disrupting connected equipment. It features a standard NEMA 5-15P input plug and provides eight NEMA 5-15R outlets, allowing you to directly power critical loads from utility power when the UPS is taken offline. This unit is essential for environments requiring continuous uptime, such as data centers or server rooms, where UPS servicing must occur without interruption. The MP2-115A model specifically supports all Liebert PSI5 models up to 1500VA.

Compatibility

This bypass switch is engineered exclusively for use with Vertiv Liebert PSI5 series UPS models up to 1500VA. It is not compatible with other UPS brands or different Vertiv UPS series. Ensure your UPS model is within the specified capacity and series to guarantee proper function and safety.

Installation Notes

The MP2-115A requires a standard 120V utility power source via its NEMA 5-15P input plug. The eight NEMA 5-15R output receptacles are designed to accept standard 120V equipment power cords. Installation involves physically disconnecting the UPS from the load and utility, connecting the MP2-115A's input to utility power, connecting the UPS output to the MP2-115A's input (if applicable, depending on UPS model configuration), and connecting the critical loads to the MP2-115A's output receptacles. Always follow proper electrical safety procedures and consult the UPS manufacturer's documentation for specific bypass procedures.
