Uninterruptible power-supply requirements

Ensure that you comply with the requirements for the uninterruptible power supply.

The following list describes requirements for the 2145 UPS:
  • Each uninterruptible power supply must be connected to a separate branch circuit.
  • A UL listed 15 A circuit breaker must be installed in each branch circuit that supplies power to the uninterruptible power supply.
  • The voltage that is supplied to the uninterruptible power supply must be 200–240 V single phase.
  • The frequency that is supplied must be 50 or 60 Hz.
The following list describes requirements for the 2145 UPS-1U:
  • The voltage that is supplied to the 2145 UPS-1U must be 200-240 V single phase.
  • The frequency that is supplied must be 50 or 60 Hz.
Note: The 2145 UPS-1U has an integrated circuit breaker and does not need external protection.
Attention:
  • If the uninterruptible power supply is cascaded from another uninterruptible power supply, the source uninterruptible power supply must have at least three times the capacity per phase and the total harmonic distortion must be less than 5%.
  • The uninterruptible power supply also must have input voltage capture that has a slew rate of no more than 3 Hz per second.
