An external maintenance bypass switch permits the seamless transfer of the critical load from the UPS output directly to the main power source. This allows the UPS system to be entirely disconnected, enabling specialized engineers to perform comprehensive servicing.
The Cutler-HammerT Maintenance Bypass Switch is a UL 1008 listed device that provides a simple and effective means for bypass- T. ing uninterruptible power supplies (UPS) while maintaining continuity of power to the critical computer loads.
Maintenance bypass switches allow for servicing or maintenance of the UPS system without interrupting power to the critical loads. Choosing the right type of switch depends on your specific application and requirements.
A static bypass switch automatically and instantaneously transfers the load to the mains electricity supply when there''s an internal fault or failure with the UPS system. It is a common characteristic of an Online UPS.
A UPS bypass switch is a non-essential addition to an uninterruptible power supply system that, while not integral to UPS operation, is definitely useful in the event of maintenance or repair.
What is a Manual Hard Bypass Switch and why are they necessary? UPS installations often include a manual wrap-around hard bypass switch, also referred to as maintenance bypass switch, or MBS. The manual bypass switch allows the UPS to be de-energized without interrupting power to the critical load.
Internal Maintenance Bypass switches, or Static Bypass switches in online UPS systems, only allow for safe maintenance work in electrically isolated parts of a UPS system. In this instance, some of the UPS areas may
Internal static bypass switches should not be confused with an external maintenance bypass switch, which is an option that enables the UPS to be powered down manually for maintenance to be carried out while the critical load is
With a maintenance bypass (MBP), utility power runs through the MBP via the UPS and then to the PDU and out to the rest of the equipment in the rack. Should the UPS need to be replaced, the power can be switched away from the
An external maintenance bypass unit consists of an NEMA-rated mechanical enclosure that has circuit breakers or rotary switches. This equipment allows for power to pass between it via the UPS and to a power distribution unit or critical loads.
