Note: UPS power upgrading is possible only if the sizing of the external
cables is sufficient. Alternatively, the external cabling must be upgraded as
well. Fuses are of the type gG.
Cable sizing is based on the standard IEC 60364-5-52 table B.52.2 and IEC
60364-5-54 table B.54.2. Sizing is for 70 ºC rated copper cables.
