Technical FAQs 4

Can a parallel redundant system use a separate battery cabinet?

There are two possible configurations for battery connection of the parallel redundant system. The two UPS modules may share the same battery cabinet(s), or each module may use a separate battery cabinet(s). Figure 7 shows a diagram of the parallel redundant system with UPS modules utilizing separate battery cabinets.

How many UPS modules can be paralleled?

A parallel configuration is not limited to two UPS modules. It frequently includes up to four modules. With some Eaton three-phase UPSs, you can parallel as many as eight modules. a single system.

Why do I need to connect UPS (uninterruptible power supplies) in parallel?

There are several reasons why you would need to connect UPSs (Uninterruptible Power Supplies) in parallel: Increased reliability: Connecting UPSs in parallel provides a redundant power source, ensuring that if one UPS fails or needs maintenance, the other UPS units can continue to provide power without interruption.

What is a parallel redundant UPS system?

For a more detailed description of UPS operation, refer to Powerware 9315 Operation manual supplied with the UPS system. The parallel redundant system consists of two identical UPS modules, a parallel cabinet, and one or two battery racks or cabinets. The parallel cabinet consists of two module output breakers designated MOB 1 and MOB 2.
