What is the Vertiv MPL lithium-ion battery cabinet?

The Vertiv™ MPL Lithium-Ion Battery Cabinet provides the benefits of lithium-ion to the Vertiv™ Liebert® ITA2 UPS from 5kVA to 30kVA. It is a 2U rack-mountable solution ideal for small spaces, providing the runtime capabilities and reliability you need.

Can a VLA battery be mounted on a rack?

Battery technology Vented lead-acid (VLA) (frequently referred to as “flooded” or “wet cell”) batteries, which are sometimes used on very large UPS systems, are ALWAYS rack-mounted. Valve-regulated lead-acid (VRLA) batteries can be mounted on racks or in cabinets. The remainder of this paper will address considerations for VRLA placement. Size

Is room lighting safe for VRLA batteries?

For vented batteries, room lighting should be intrinsically safe to avoid explosions caused by sparks igniting hydrogen gas. For VRLA batteries normal lighting may be used. This does assume that the correct battery charging characteristics are used and correct ventilation has been provided.

Are VRLA batteries flammable?

Because even VRLA batteries can vent hydrogen gas (which is flammable and possibly explosive), ventilation (i.e., air exchanges per hour) must be sufficient to ensure that no pockets of gas can collect at the lower flammability limit (LFL). Local codes will dictate the safety margin, which is usually at least 50% below the LFL.

How do you protect a VRLA battery?

For VRLA batteries the simplest of protection is normally acceptable but rooms housing vented battery types need to be impermeable for battery acid or alkaline for nickel cadmium types. An alternative to having a complete floor treated is a bunded floor lip, which prevents any spillage from spreading beyond the immediate vicinity of the battery.

How far should a VRLA battery be from a monobloc?

Looking specifically at cell or monobloc spacing to allow a flow of air between the units, it is reasonable to allow a minimum gap between VRLA cells and monoblocs of 5mm. It would also be prudent to increase this distance where the battery is housed in an enclosure. Batteries in enclosures are best mounted on rails rather than a solid shelf.
