Input currents
Currents and measurement conditions
N.B. Currents are measured at:
- full rated load, PF = 0.8
- rated voltage of normal AC source is
400 V
- battery float charging.
For normal AC-source rated voltages of
380 and 415 V, multiply the I1 and Iu
values by 1.05 and 0.96 respectively.

(1) Protection devices for single-UPS units, supplied with 400 V, 50 to 60 Hz, confirmation required.
Check compliance with local standards and suitability for specific installation conditions, notably:
 withstand for short-circuit current at point of installation
 protection of static-switch semiconductors with respect to maximum permissible currents
 discrimination with UPS output protection devices in case of operation via the bypass.
(2) Depending on the installation short-circuit current.
