SPECIFICATIONS
The following are electrical and environmental specifications for the HA32A UPS.
AC Input (MAINS1) Ratings
Refer to Table B–1 for nominal voltage (Vac) values available.
Voltage:
As specified, n10%, -15%
Frequency:
Nominal, ±5%
Phases:
Three-phase, phase rotation A, B, C
Wires:
Three, plus equipment ground
Current: See Table B–2
Power Factor: 0.82 lagging minimum at full load output, nominal input voltage, and
normal float voltage on the battery
Bypass AC Input (MAINS2) Ratings
Voltage: Must match UPS nominal output voltage ±10%
Frequency Window:
Nominal, ± 0.25, 0.50, 0.75, or 1.0 Hz. Standard setting for bypass
input frequency window is ±0.50 Hz, unless otherwise specified when
ordered. The frequency window can be changed after the unit is
installed, but only an authorized Digital Services representative can
modify the equipment.
Phases: Three-phase, phase rotation A, B, C
Wires: Four-wire Wye (the HA32A-Cx models do not require a Wye source or
a neutral conductor)
Current: See Table B–2
Power Factor: Load-dependent
