The first six paragraphs of clause 5.12 in the tender (page 49-50) have been annulled and replaced

with the clauses below

5.12.0. Battery system general requirements

h) The battery voltage and capacity shall be such as to fulfil the

inverter input power requirements when the inverter is delivering

its rated output (VA), for an autonomy time of 4hours.

i) The battery system shall consist of two battery banks each with its

own battery cabinet. Each battery bank shall consist of valve

regulated, lead acid batteries (VLRA), with each battery rated at

12V. Batteries shall be connected in series to form a batteries string

one or more parallel battery strings shall be connected to form a

battery bank of a high DC voltage suitable for the UPS rating.

j) Each battery bank shall offer an autonomy of two hours at rated

UPS output giving a total of 4 hours for both battery banks. The

nominal ampere-hour (Ah) capacity of the battery system supplied

with the UPSs shall be for 4hr autonomy at full load The Nominal

Ampere-hour capacity of the battery shall be calculated in line

with a battery manufacturer’s approved battery sizing tool and

shall include all necessary allowances as specified in the datasheet,

required to compensate ageing effects that result in the progressive

loss of capacity

k) Each battery bank shall have a fused isolator for connecting the

battery bank to the UPS.

l) A cable shall be provided for connecting each battery bank to the

UPS. Cable shall be armoured and rated for 120% of maximum
