The lower ground was then fed via a new Vertiv 200kVA UPS in an N+1 arrangement located within the New purpose built UPS area on the Lower Ground floor. The remainder of the building was supplied by a Vertiv 160KVA UPS in an N+1 arrangement located within the new purpose built UPS area on the lower ground floor.

Each of the new UPS systems includes rack mounted batteries to give a minimum of 10 mins end-of-life battery autonomy at full load capacity.

The units were enclosed within separate, fire-rated, rooms to maintain full resilience.

Each new dedicated UPS room was configured to house 1 of the Vertiv 200 kVA UPS units 1 of the 160kVA) UPS unit.

All sub main cabling from the UPS Systems to the downstream distribution boards was replaced as part of these works.

New essential distribution boards were installed, served by the new UPS systems. A new mechanical plant distribution board was also installed as part of the works.
