Preparing your uninterruptible power supply environment
This topic provides information you need to ensure that your physical site meets
the installation requirements for the uninterruptible power supply.
Attention: Ensure that you comply with the following requirements for
uninterruptible power supplies:
v
Each uninterruptible power supply should be connected to a separate branch
circuit.
v
A UL listed 15 A circuit breaker must be installed in each branch circuit that
supplies power to the uninterruptible power supply.
v
If a rack power distribution unit is used, each uninterruptible power supply
must be connected to a separate power distribution unit.
v
The voltage supplied to the uninterruptible power supply must be 200–240 V
single phase.
v The frequency supplied must be between 50 and 60 Hz.
Note: If the uninterruptible power supply is cascaded from another
uninterruptible power supply, the source uninterruptible power supply must
have at least 3 times the capacity per phase and the total harmonic
distortion must be less than 5% with any single harmonic being less than
1%. The uninterruptible power supply must also have input voltage capture
that has a slew rate faster than 3 Hz per second and 1 msec glitch rejection.
